How to
choose an Alternative Spa, Swim Spa or Hot Tub
Sanitizer? The phrase "Alternative Sanitizer" usually refers to
something other than conventional forms of
chlorine: the most popular sanitizing product.
Alternative Spa Sanitizers include: salt
chlorine generators, ionization-oxidation,
ionizers, mineral sanitizers, ozone generators,
ultraviolet sanitizers, biguanide (Trades names
such as Baquacil, Baqua-Spa, Soft-Swim and
Revacil) and bromine. Some alternatives perform
best by being used in combination, while others
can be stand alone. Some alternatives are other
chemicals and others are generating or releasing
devices. The quest for perfect spa and hot tub
sanitizing is ongoing. The goal is better
sanitizing, more convenience, less chemical
sensations and safety. What is right for any spa
or hot tub will depend on how it is used, by
whom it is used, bather demand, importance of
convenience and cost considerations. No matter
which sanitizer is used, it is a good practice
to shock the spa at least once a week, after
periods of heavy usage and at distinct signs of
a loss of water quality. This will help to rid
the water of organic buildups and prevent the
development of resistant microorganisms. If

► The Right Tester &
Sanitizer?
I have invested in nearly a year's
supply of biguanide chemistry with the purchase of my new
spa. My wife has sensitive skin and I thought biguanide
would be the answer, I hope I have not just fallen for the
biguanide hype. I spoke to the manufacturer about clarity,
slippery walls and foaming and they suggested that I have
the water analyzed at a professional pool store. They said
that the slipperiness was probably caused by the hardness
not being high enough and the foaming could be cause by the
water not being hard enough or too much chemistry in the
water. I have been chasing this for a while so there is a
lot of chemistry in the water even though it is only a
couple weeks old. I took both spa water and unaltered supply
water in for analysis and they used the same test strips I
have at home, but put them into a computerized reader and it
printed out the results. I have a 485 gallon spa. The
analysis showed the pH was 8.1 and they recommended 2 oz. pH
Down; the Biguanide was 25 and they suggested 2 oz. of
biguanide sanitizer and the hardness was 160, the dealer did
not recommend hardening the water, but I added the
recommended 10 oz of Hardness Increaser because biguanide
manufacturer said this could be part of the foaming problem.
I added the chemistry last night and this morning my spa is
still slightly cloudy and is still foaming. I added some
Foam Disperser and that helped a lot. I also added some
biguanide water clarifier to see if this might help by
tomorrow. I got the analysis of the supply water and if the
spa does not sparkle up and the foaming go down I may drain,
clean the filter and start over. I didn't use to have a
foaming problem so it may be a build up of chemistry. The
water is not that old but I have been chasing this problem
for a couple weeks now and have tried a lot of different
things. My question is, would it be a worthwhile investment
to purchase your ColorQ Biguanide PRO 5 Water Analyzer so I
could hopefully dial in the biguanide chemistry or should I
abandon biguanide and a couple hundred dollars of chemistry
to try another system? I would hate to buy the analyzer,
then abandon biguanide, that would cost a lot of money. Can
this analyzer be used for other systems too if I change
systems? I like the idea of biguanide being non-irritating
and we have been very happy with the results so far. except
for the clarity and foaming issues. I don't mind putting in
effort and expense to get the biguanide balanced and
effective, but if the time and money are wasted and I will
never get the results I want I might as well bite the bullet
and switch to another system. Should I buy the analyzer? Is
it accurate enough to get my spa dialed in with biguanide or
is it a losing battle?
Jim H. Temecula, CA, 7/4/2010
I wasn't planning on answering letters today, but yours hit
a chord. Although I do sell a
tester for biguanide, I
suggest that you not purchase it, even if it is a better
tester than what the dealer is using. The reason being, that
I suggest you permanently switch to another sanitizer. Test
strips, even the best, are not precise. In my opinion, using
a scanner and computer to read them, doesn't increase the
precision and may actually provide less reliable results.
Have them run the same sample twice and see what happens.
The slimy walls are a positive sign of inadequate
sanitation. It is not uncommon, for biguanide users to
develop sanitizer resistant microorganisms. Some dealers do
everything that they can, to keep you using the product, not
because it is chlorine free, but because it is profitable.
Foaming and biguanide go hand in hand, as the material is
known to foam, when agitated or aerated. Foam presents
another sanitizing issue, as proper sanitation demands that
the foam be eliminated, at some point. Otherwise, the
ecology of the foam will be different, from that of the spa
water. The problems you are experiencing will only get worse
and will continue to be a wasteful expense. I suggest that
you drain and clean the spa and prepare to use another
sanitizer. I realize that your wife has chemical sensitivity
issues, which drove you to biguanide, in the first place. I
agree that chlorine, as used in a spa, can be both odorous
and irritating and can detract from the experience. Bromine
would be a better choice in terms of both odor and
irritation. Instead of simply using bromine at the suggested
3-5 PPM, I suggest that you consider using alternative
sanitizers, that can be chemical-free or add only minimal
amounts of innocuous metallic ions. If this is done, the
bromine usage will be minimized, to the point that its
presence will go unnoticed. With the right equipment, almost
any measurable amount will be enough. You can use a
SPA
FROG Mineral Sanitizer and an
UltraPure Ozone Generator and
come close to only requiring a trace of bromine. If all that
is required is a small amount to maintain a low bromine
level, it acts as confirmation that everything is working up
to par. You could also add a
Delta UV Sanitizer, which adds
no chemicals at all and kills virtually all microorganisms
passing through the cell. It isn't used alone, but can be
combined with other alternative sanitizers, to help reduce
the chemical presence and afford real backup sanitizing. A
salt chlorine generator works very well. by itself, or in
combination with these alternative spa sanitizers. It is the
better way to do chlorine. I hope that this information
will prove helpful. Have a happy July 4th.
Sincerely. Alan Schuster, 7/4/2010
► Hot Tub
Chemicals?
I have a new hot tub, 1325 litres. The
company recommends a treatment program consisting of several
chemicals. This series of chemicals is used to treat hot tub
water and starts with a product which is a granular
chlorine. After addition, the water is let be for 12 hrs
before adding any other product. Assuming pH, alkalinity,
etc. are OK, then you add a product which is an Oxidizer and
a Clarifier. This procedure is supposed to last approx. one
week, with only having to keep the chlorine @ 3+ ppm. The pH
and alkalinity have to be maintained. My question is, having
gone thru a case of "folliculitis", is my tub receiving the
proper sanitation with this system and, if not, can you
recommend a proper type and procedure? I should mention also
that every time I use the tub I get itchy where the
"folliculitis" was. Please help.
Ken M., Chatham, Ontario, Canada, 1/14/2004
One of the consequences, of failing to maintain a proper 1-3
PPM level of Free Chlorine is the possibility of
folliculitis. The only chemical that you are adding, that is
a sanitizer, is the chlorine product. I suggest that you
test for Free Chlorine, before and after each use. If too
low, add more chlorine and allow 1/2 hour to sanitize before
retesting and using the spa. It is a good practice to shock
the spa at least once a week, after periods of heavy usage
and at distinct signs of a loss of water quality. This will
help to rid the water of organic buildups and prevent the
development of resistant microorganisms. It is a good
practice to shock the spa at least once a week, after
periods of heavy usage and at distinct signs of a loss of
water quality. This will help to rid the water of organic
buildups and prevent the development of resistant
microorganisms. The addition of an Ozone Generator will help
the chlorine sanitize better because ozone will do more of
the oxidation of wastes and byproducts. Please refer to the
archives for more information on chlorine alternatives and
related topics. I hope that I have been helpful.
Sincerely. Alan Schuster, 1/14/2004
► Can't Use
Chlorine Or Bromine?
I'll bet that this one will stump you.
My wife and I cannot use chlorine or bromine without
affecting our Iodine levels and our thyroid. Our doctor
suggested using Iodine as a sanitizer since it is a member
of the Halogen family (fluorine, chlorine, bromine, iodine).
I searched the web and found many sites referencing the use
of Iodine, but only one briefly mentioned the PPM of 7-10
for a wading pool. Do you know what the PPM should be and
what would be the best oxidizer to use. One site mentioned
Hypochlorite which reintroduces chlorine back into our spa.
We are currently using a non chlorine shock. The water is
reasonably clear; algae and odor free, and has the slight
greenish tinge that the web sites described for Iodine
sanitized spas. We do get foam, shortly after adding the
Iodine which de-foaming products easily take care of. pH is
7.8, when I add pH minus it comes down for a while then
creeps back up. Total alkalinity is about 120. Any advice or
tips for using Iodine would be appreciated. Of all the
information sites I have found yours is the best. Thank you.
Bruce M., 9/28/2006
Close but no prize. Unless this is an EPA registered
sanitizer, I don't feel that this is an area that I want to
venture into or that you should pursue. Instead, let's help
you maintain a spa without non-chlorine shock, chlorine or
bromine and with fewer chemicals. Add a
UV sanitizer. It
will kill virtually all of the microorganisms in the return
flow, without any chemicals. UV sanitizers require that an
oxidizer be added to the water, to destroy organic wastes
and accumulations. Instead of using non-chlorine shock,
chlorine or bromine, you can use an ozone generator. It only
adds a form of oxygen to the water. Because ozone does not
remain in the water for prolonged periods of time, you
should have a persistent sanitizer, that will prevent growth
in the spa water and on the underwater surfaces. Add the
SPA
FROG Mineral Sanitizer and all that you will be adding is a
trace amount of silver ions. Fewer chemicals will be
required and the water quality will be better. This regimen
will be easier to maintain and halogen free! I hope that
this information will prove helpful.
Sincerely. Alan Schuster, 9/28/2006
► Natural
Sanitizing?
Alan,
We're just about ready to have our hot tub installed. I've
been looking at the various ways to keep the water clean. I
came across this a natural enzyme based product. Is this for
real, what would be the shortfall using this method to keep
the hot tub water clean? Thanks for all your ideas, they are
very informative.
Rick B., Rochester, NY 4/8/2011
If you don't control infectious bacteria, such as
pseudomonas and e. coli, you can end up with a rash or
worse. This product is not a recognized sanitizer. I have
heard it described as being like lake water. Check the
label. Does it have the EPA Registration number that a
sanitizer must have? Evidently, this product, can under
certain circumstances, work. I suspect that it can be
overwhelmed due to high bather usage and that can lead to
problems. I would rather use a product that I can measure
and test and that works under virtually all properly
maintained conditions. I suggest that you consider a more
traditional spa water sanitizer. Bromine, Chlorine,
Salt
Chlorine Generators and a Mineral Sanitizer in conjunction
with an Ozonator or
Ultra-Violet Sanitizer will afford much
greater protection. I'm glad that you found the website
helpful. Good luck and enjoy the spa.
Sincerely. Alan Schuster, 4/8/201
► A Switch
From Chlorine?
For health reasons, my husband and I
have decided to change our method of cleaning our tub. We
are looking for something all natural, and have been advised
to investigate using a copper ionizing system. What do you
think of these systems, particularly the Copper-Zinc Core
Spa Filter? Thank you.
Kimberly M., Vandalia, Ohio, 9/1/2008
I suggest that you consider the use of ozone and a
Spa FROG mineral
sanitizer, along with a low level of bromine. The addition
of an ozone generator
and mineral sanitizer is something
that will make maintenance easier
and produce higher quality water.
I hope that I have been helpful. Copper is better in a pool
application, as it exhibits algaecidal properties. The
problem in a spa is primarily bacterial. The SPA FROG is
recognized and registered by the EPA, as both a spa
disinfectant and sanitizer. It is the only such product with
these designations. It uses silver ions to control
microorganisms. I hope that this information proves helpful.
Sincerely. Alan Schuster, 9/1/2008
► An
Algaecide In A Spa?
We have a spa that is located outside
and is used all year. In the summer, we don't use the heater
and more or less use it as a pool for the kids. Should I be
adding algaecide - like they do in pools?
T. S., Sarasota, FL, 12/6/2003
Most spas do not use an algaecide. Inasmuch as spas are
usually heated and, therefore, are covered when not in use,
the normal spa sanitizers are able to control algae. In your
case, especially, if the spa is left uncovered in the
summer, the addition of an algaecide might be worthwhile.
However, you cannot add just any algaecide. The only one
that I would recommend is the Polymer (polyquat) type. Other
algaecides could cause excessive foaming, in a spa, and
should not be used. The polymer types are non-foaming.
Follow the label directions and use an appropriate amount! I
hope that I have been helpful.
Sincerely. Alan Schuster, 12/6/2003
► Needs More
Than Just Hydrogen Peroxide?
Our sole water supply is lake water.
In our hot tub we use only hydrogen peroxide as a sanitizer
for health reasons We are finding that we must shock it
daily with at least a cup of hydrogen peroxide to get it up
to the required ppm. You mention adding a mineral sanitizer.
Will this make it ppm hold longer? Is a "mineral sanitizer"
a natural product?
Carol G., 1/6/2010

Hydrogen peroxide is not recognized as a spa sanitizer.
You could add a SPA FROG mineral sanitizer, as well,
since it will provide additional,
persistent sanitizing. It is EPA
registered as a spa sanitizer and
disinfectant. However, it must be
used with an oxidizer. While
hydrogen peroxide will fill the
oxidizer role, I am not sure if it
will suffice. In any case, it will
improve the current situation. All the SPA FROG
adds to the water are silver ions. You can reduce the
hydrogen peroxide requirements, by using a
METALTRAP 1
Micron Pre-Filter to treat all new water. It simply attracts
to a garden hose. You can also use it, with a small
submersible pump, to recirculate the hot tub water. This
will remove organic contaminants and even many
microorganisms, that have built up, due to bather usage. I hope that this
information proves helpful.
Sincerely. Alan Schuster, 1/6/2010
►
Copper-Containing Product?
Thank you for taking a question! I
have read on your site that it is not recommended to use
copper sulfate primarily in a pool. Of course, our pool
installer is really pushing a copper sulfate product to use
instead of chlorine. I am guessing that this is a new
product that is not dangerous in large quantities. as normal
copper sulfate would be. Are you familiar with this new way
of keeping a spa clean? Any advice would be greatly
appreciated. Thanks.
Catherine, 3/19/2008
Copper sulfate cannot replace chlorine! Chlorine is a
sanitizer and an oxidizing agent. Copper acts, primarily, as
an algaecide. Copper can be useful as part of an overall
pool maintenance program, in conjunction with other
products. Copper sulfate must be used only at very low and
controlled levels: otherwise, staining and discoloration can
result. Virtually all of the copper containing products are
based on some chelated (stabilized) form of copper. Copper
is rarely used in spas. What spas need are active sanitizing
and oxidation: something best provided by the use of
ozonators,
mineral sanitizers,
salt chlorine generators,
chlorine and/or bromine. The product that you are referring
to is not copper sulfate, but is some complexed form of
copper. While it might provide some control of algae and
bacteria, it cannot be used as a stand alone water
treatment. It must be used with an oxidizer or shock. If you
want a spa that is less reliant on chemicals, consider an
ozonator! All you will need to do is maintain a low level of
a backup sanitizer, such as a mineral sanitizer chlorine,
bromine or possibly this copper product. Shock will not be
required on a regular basis, because of the ozonator. Water
maintenance will be easier and the quality will be better. I
hope that the information proves helpful.
Sincerely. Alan Schuster, 3/19/2008
► Hydrogen
Peroxide?
We have a hot tub and would like to
use hydrogen peroxide instead of the normal chemicals. My
husband is allergic to the chlorine and bromides. How much
Hydrogen peroxide do we use and what %. We were told that it
should be a 10% concentration but we can't find any hydrogen
peroxide above 3%. I thought maybe you could help us. Also
do we nee to use any kind of a shock at the first? Hope you
can help? Thanks.
Jo, 7/10/2005

I am not sure that using just hydrogen peroxide will provide
adequate sanitation. In pools and spas, it is used as a
shock treatment with biguanide. It is available in
concentrated form in many pool and spa outlets that offer
biguanide products. Have you considered the use of an
ozonator and a
mineral sanitizer or ionizer. This
combination would come close to being chlorine and bromine
free. The ozonator could negate the need for hydrogen
peroxide and a mineral sanitizer or ionizer would release
metallic ions and act as a persistent sanitizer. Hydrogen
peroxide can be used as a shock treatment, with a mineral
sanitizer or ionizer as the primary water sanitizer.
However, in most cases better results are obtained, if you
maintain a low level of chlorine or bromine, which you can
add during periods that the spa will not be used, along with
a mineral sanitizer and ozonator. I hope that I've been
helpful and given you some food for thought. Good luck with
your decision.
Sincerely. Alan Schuster, 7/10/2005
► Just
Hydrogen Peroxide?
I have started using Hydrogen Peroxide
in my hot tub and I need some help. I started with fresh
water (400 gallons) and added 1 cup of Hydrogen Peroxide.
This appeared to work great for the first couple of weeks.
Now, it has been about four days since we used our hot tub
and when I opened it up, the water was quite discolored
(greenish-brownish). What can I do? Do you use other
products in conjunction with Hydrogen Peroxide such as pH
products. My hot tub is outside. Thank you.
Shelley, 9/25/2009
Hydrogen peroxide is not recognized as a spa water
sanitizer. It has to be used in conjunction with a
persistent sanitizer and the overall spa water chemistry has
to be maintained. Your description of the water proves the
point! The addition of an ozonator is something that
you should consider, as it will make maintenance easier and
produce higher quality water. It will reduce the chemical
consumption. You might add a Spa FROG mineral sanitizer, as
well. The combination of the two work well together. All you
should need is a very low level of bromine, as it will act
as confirmation that proper conditions are being maintained.
Instead of the ozonator you could use the hydrogen peroxide.
I believe that you better off starting with a clean slate. I
would clean the spa and start anew. Have the source water
tested for metals. If present, you should use a
METALTRAP
Filter, to remove heavy metals, which can cause staining and
discoloration. I hope that this information helps get you
off to a better start.
Sincerely. Alan Schuster, 9/25/2009

Questionable Sanitizer Advice?
It looks like I have developed a skin
reaction/rash to Potassium Peroxymonosulfate that I have
been using in my hot tub. The product has 45.2% Potassium
Peroxymonosulfate that has 4.7% active oxygen). I am
wondering if I can use hydrogen peroxide (H202) instead and
what the differences are between these two compounds (eg:
will H202 cause the same skin reaction as Potassium
Peroxymonosulfate). Do you think the H202 products that
another web site mentions are OK to use? Here is what the
relevant sections says: "Hydrogen peroxide is available at
most spa stores, under the category of oxidizers or shock
treatments. Since it is sold as a cleaning agent, most spa
stores are unaware of its value as a sanitizer. Several
brands don't even indicate the contents on the bottle. (A
Federal MSDS Report can be requested from any manufacturer
for a list of ingredients and potential health hazards.)
Three brands are certified to contain 27% hydrogen peroxide:
Another web site says to get H202 test strips and maintain
the H202 level between 50 and 100 ppm. I am hoping that H202
will do the trick to allow me to sanitize my hot tub and not
have to use bromine tablets, which I used to use but don't
anymore due to their (or their by products) cancer causing
properties. Thanks in advance for your help.
Brad B. in California
27% Hydrogen peroxide is dangerous stuff. It is not
registered by the US EPA as a spa sanitizer - only as an
oxidizer. To suggest that it is a spa sanitizer would be a
violation of federal law. I have gotten numerous complaints
about rashes, due to excess MPS. I also have gotten letters
about bromine rashes. Bromine tablets contain something
(dimethyl hydantoin) not found in chlorine pools or spas, so
you may not have encountered this chemical before. I would
give them both up and go with dichlor chlorine, a Spa Frog
and Ozone. The ozonator will eliminate the odors, normally
associated with chlorine use. Chlorine has a long, safe
history of use. Free chlorine is the active sanitizing form
of chlorine and the recommended level is 1-3 PPM. Very much
higher levels can be irritating. As a backup to chlorine and
to allow good results, while maintain a lower chlorine
level, you give thought to adding the
SPA FROG Mineral
Sanitizer. It is an EPA registered spa sanitizer and
disinfectant and will help you maintain a free chlorine
level at 1/2 of the normal level and still maintain proper
sanitation. To further improve the water quality, an
ULTRAPURE Ozone Generator will make a big improvement and
reduce chemical usage. It will provide oxidation and reduce
chlorine usage. The ozone is short lived and adds nothing
else to the water. I hope this information will help make
the hot water experience more pleasant.
Sincerely. Alan Schuster, 1/8/2010
► Sensitive
To Chlorine?
We recently purchased a vinyl hot tub
and are running it inside in our bedroom. I just learned
about NTM and the dangers of inhaling the microorganisms
while soaking in the tub. Can you tell me if enzyme products
are effective against NTM (I am sensitive to chlorine so
that is not an option for me). We are currently using a
product, which the dealer said was approved for hot tub use.
My understanding is that it is a copper based product, which
is also used as a pesticide. Although it may be better than
chorine for me, I would prefer something more natural.
Anything we would use would have to be OK to use in this
type of tub. We look forward to your assistance.
M. M., Maine, 2/24/2004
Non Tuberculosis Mycobacteria (NTM), according to Center for
Disease Control (CDC) information, is not something unique
to spa or hot tub use. These are bacterium, that are found
in the environment, and can be opportunistic in their
growth. Bacterial growth can be the direct result of
inadequate sanitation. Although chlorine and bromine are
effective spa sanitizers, I can appreciate that you are
sensitive to chlorine (and probably bromine, as well) and
need to find an alternative spa sanitizer. However, you are
relying on products that are NOT bactericides! Enzyme
products are not approved spa sanitizing agents. I am
not familiar or knowledgeable about the specific product,
that you are referring to, but if it does not have an E.P.A.
registration number, it is not a registered spa water
sanitizer. The other product may be approved for use in your
tub, but it is NOT a bactericide. It functions as an
algaecide and that does make it a pesticide. However, not
all pesticides are bactericides! You have several good
choices, of alternative spa water sanitizers, including:
ozonators,
mineral sanitizers, ionizers,
uv sanitizers,
biguanide or a combination of more than one. An ozonator can
be used with either a mineral sanitizer or ionization
unit and can provide effective spa water sanitizing with a
minimum of chemicals. Biguanide can be used, in conjunction
with hydrogen peroxide, as a spa sanitizer. Please refer to
the archives on these products for information on their spa
usage. I hope that you will help this information helpful.
Sincerely. Alan Schuster, 2/24/2004
► No More
Bromine?
Over the past 12 years of enjoying my
spa, I have developed an extreme intolerance of bromine.
Even very low levels of 1 ppm or less are enough to trigger
an eczema rash. Last year, I tried switching to a copper ion
sanitizer system ,which immediately eliminated the rash
problem, but I have discovered that copper ion is banned in
Canada due to its effect on fish populations. My question:
Is there any reliable long-term sanitizer system that is
completely bromine and chlorine free? I have an ozonator,
which is an oxidizer only and must be backed up by a
sanitizer. Biguanide seems to be only a short term solution
only because of the tendency to build up resistant
organisms, and following the links to the mineral sanitizers
and UV sanitizers you mention suggest that they reduce, but
not eliminate the need for bromine.
Graeme S., British Columbia, 1/8/2008
Assuming that you're a typical person, you have been in
swimming pools that used chlorine. You may not like the
smell, but you should be able to virtually eliminate any
significant odor. The point is that you are probably not
sensitive to chlorine. Bromine tablets contain dimethyl
hydantoin. This chemical is only found in bromine-sanitized
pools and spas. The high spa temperatures make development
of a rash even more likely. The first thing you should do is
drain and clean the spa. That will get rid of the dimethyl
hydantoin. The ozonator will
provide all the oxidation the spa should require. The
problem is that it is short-lived and a persistent
sanitizer is required. The copper helped fill that role. It
is best to run the ozonator for
periods spread throughout the day. You still need a
persistent sanitizer and I suggest chlorine. Keep the level
at 0.5 to 1.5 PPM. Both the ozonator and oxidation units
will destroy the odorous, irritating forms of chlorine,
resulting in little or no odor. Because there is so much
oxidation, the chlorine will only be needed for sanitation
and not oxidation. It should take very little chlorine to
maintain this level, if the ozonator operating,
intermittently, throughout the day. Biguanide sounds like a possible choice, but
my mail suggests that you will encounter problems, within a
few years and have to make a switch. You seem to have
concluded the same. As for the rash and this regimen, please
discuss this with your doctor. Please let me know how this
works out.
Sincerely. Alan Schuster, 1/9/2008
► How Does A
Mineral Sanitizer Work?
I'm using a Mineral Sanitizer
Cartridge in my spa. I add some non-chlorine shock after
each use. I like it because there is very little odor, if
any. Exactly, how does this cartridge replace chlorine?
Dennis G., 2/22/2005
The cartridge contains silver, in a form that allows for
slow release into the spa water. This is done without the
use of electrical components, as is the case with Ionization
Units. The silver is released into the water in ionic form.
This is the most active form and allows the ions to function
as sanitizers, at very low concentrations. Chlorine is
normally used to provide this type of sanitizing
action. However, chlorine will also destroy and decompose
organic wastes and debris. Because metallic ions cannot
destroy the organic contamination or prevent further
buildups, it is necessary to add an oxidizer to do this job.
That is the reason for adding the non-chlorine shock.
Maintaining a free chlorine of that favors the low end of
1-3 PPM, helps assure proper sanitation, at all times. The
use of the Mineral Sanitizer should reduce the overall
chemical usage and make control of the water chemistry
easier. An ozone generator is the easiest and best way to
perform the oxidation of wastes and byproducts, without
contributing chemicals or odors. Enjoy the spa. I hope that
I have been helpful.
Sincerely. Alan Schuster, 1/15/2005
