How to help
make your spa, swim pa or hot tub kid
friendlier? Apart from the
obvious water safety factors, consideration
should be given to sanitizer choices, water
temperature and length of bathing time. Kids
tend to spend a lot of time in the water and,
ultimately, depend on the adults for the
important matters of pool safety and water
quality. If problems arise, refer to the

Problem-Solving Information, in a question and
We would like to allow our small child
to go into our spa with us at a temperature around 89-92°F
degrees. I have been told the best alternatives to using
straight chemicals are a Mineral Purifier then a
non-chlorine shock at exit. Do you have any opinion. Thank
Holli S, 5/9/2017
Mineral Sanitizers are products that sanitize by using
metallic ions, such as silver. Just using a mineral
sanitizer is not enough. To maintain proper spa water
quality, you need to use an oxidization, as well. That is
the purpose of the non-chlorine shock. So long as the
product choice includes both capabilities, I see no problem.
However, my own preference would be to use an
ozonator and a
mineral sanitizer. This way there's less shock treatment and
there is built-in backup sanitizing. Maintaining a low free
chlorine level, will help confirm that the ozonator and
mineral sanitizer are maintaining proper conditions. It
should take very little chlorine to maintain this low level.
I hope that this information proves helpful.

► Spa Use By
year old daughter loves to get in the hot tub with my
husband. I do not like it because he keeps it @ 105 degrees.
It does not seem to bother her at all. She says "I love it."
He is very careful not to let her stay in more than just a
couple of minutes at a time. Should I worry about these
brief moments with dad? Is it OK to let her stay longer if
she wants to, and she does. Thanks.

I share your concern. Firstly, 105°F is above the
recommended maximum of 104°F. Spa bathing recommendations
are not written with a 2 year old in mind. Given the low
body weight, the spa water can cause a fairly rapid rise in
body temperature. Short bathing times, with less than full
body immersion are probably a necessity. In any event, I
suggest that you discuss this with a pediatrician, inasmuch
as I am not really qualified to take part in this decision.
A child's skin is more likely to be sensitive to the water
chemistry and sanitizing. Make sure that you keep tabs on
both, before each use. Using a ColorQ Digital Water Analyzer
will give you reliable results, without any color-matching
or guesswork. Enjoy the spa.

I just purchased my first home it has a pool and a spa. I
let the pool guy take care of his end but I manage the spa
levels. When I moved in the spa was full, with a Bromine
Floater. I tested the water several times with a kit that
was here when I moved in, 5 drops of yellow stuff, 5 drops
of red stuff you know the kit. I always got very high
bromine levels. Not sure if I was testing correctly I took a
water sample to my local pool/spa supply "expert". I was
advised by the "expert" to drain the spa and switch to
chlorine, which I did. Now I filled the tub added the metal
gone and then later the granulated chlorine. Tested the
levels about 3 hours later and WAY too much chlorine. Took a
sample to the "expert" and was advised to let the chlorine
stabilize for a couple of days before adding any "spa-up or
spa-down". Two days later I tested the water, pH normal,
Chlorine, does not register. The chlorine side is as clear
as the original sample. Like I never added the yellow stuff.
Well I am not stupid. No yellow in the cylinder means MORE
chlorine. Added more chlorine. Tested 2 hours later, the
test results were way to much chlorine. Waited 2 days with
no use of the spa and tested again. NO CHLORINE! But the pH
is almost ideal. How often should I need to add chlorine to
a spa that is set to 103°F But is only used once or twice a
week? The spa is always covered and has minimal use. Should
I ignore the local expert and switch back to the Bromine
floater, or do I need to adjust my spa levels on a daily
basis even though I use it on a bi-daily basis? One more
question before I end this log winded, very confusing
e-mail. I have a nine year old daughter who wants to enjoy
the spa with me. I have been told by friends that have spa's
that 103°F is too hot for someone her age. Is this correct?
If so what is an ideal temperature for a child her age?
Thanks for any help, Cold and confused.
If your pool and spa are separate and do not share common
water supplies, I would prefer the use of bromine. It has
less odor and allows for easier addition. There is nothing
Houdini-like happening! The chlorine or bromine levels drop,
if there is organic wastes present, such as after bathing.
The test kit that you are using will suffice for bromine
use, but it provides inadequate information, when chlorine
is being used. I would prefer using a test strip, such as
LaMotte Insta-Test, as it furnishes truer data on the state
of the sanitizer level. Still better would be an
ColorQ Tester, which eliminates color-matching and
guesswork. You should test the water at least several times
weekly, even if it is not being used. You don't want the
sanitizer level to bottom-out, as it will made catch-up more
difficult. If you use the floater with bromine, all you
should require is pH increaser and, perhaps, a dose of shock
after each use of the spa. If you would like assure even
better water quality with less work and fewer chemicals,
consider adding an ozone generator. This will allow the
bromine to function in a back-up role and will reduce the
chemical sensation. The body mass of your 9-year old
daughter is far less than that of an adult. Immersion in
103°F water will cause the temperature of her internal
organs to rise more quickly, than that of an adult. Hence,
you should lower the temperature, reduce the bathing time
and the extent of immersion or all of the preceding. In any
case, I would defer to the good judgment of the family
doctor or pediatrician. I hope that the information proves
helpful. Enjoy the holidays.
