stain treatments on the market today, the METALTRAP™ STAIN
REVERSAL KIT includes the revolutionary, patent-pending POOL
REFRESH product, specifically designed to remove the metals
permanently from your water so staining is likely to re-occur.
Here’s how it works:
Step 1: Test your stain. (see directions below)
Step 2: METALTRAP™ STAIN REMOVER removes stains, pulling
the metals off the finish and back into the water. Basically,
this step converts the metals from their solid form back into
their dissolved liquid form.
Step 3: POOL REFRESH safely reacts with the newly
dissolved metals to increase their particle size large enough to
be removed by your standard filter.
Step 4: When rebalancing water chemistry, add LIQUID
METALTRAP™ to deactivate any lingering metals or new metals
introduced into the pool water to prevent future staining.
Step 5: Use METALTRAP™ quick-connect hose filters every
time you add new water to your pool or spa so no new metals are
introduced to your clean, stain-free pool.
STEP 1—STAIN TEST: Metal stains can be many colors:
green, black, red, brown, gray, purple and many variations of
each. Can the stain be brushed off? If yes, then the area may be
organic debris or algae. Have you tried Chlorine? If yes and
stain persists, it’s likely to be metallic in origin (Iron if
light brown, Copper if bluish green, Silver if dark gray,
Manganese if dark brown or purple).
No expensive Stain ID Kit is needed. Simply do our “lemon test”
to be sure it’s metals before proceeding with a stain reversal
Lemon Test Directions: Cut a lemon in half. Rub the lemon on a
small section of the stain. For stubborn stains, squeeze the
lemon gently and leave the lemon on the stain for 2-3 minutes.
If the stain lightens or lifts in any way, you know it’s metals
and our METALTRAP™ STAIN REMOVER will remove the stain
METALTRAP™ Stain Remover is an all-natural, metal removing
formula that chemically pulls iron, copper and manganese stains
off pool and spa surfaces such as fiberglass, vinyl liners,
plaster finishes, plastic returns, main drains, and also from
tile grouts. Metal stains are less likely to re-occur when this
product is used in combination with our POOL REFRESH and
METALTRAP™ Pre-Filter products.
For best results, clean your filter and adjust your water
chemistry as follows: Chlorine Level (0-0.5 ppm), pH (7.0-7.2),
total alkalinity (50-90) and phosphates (below 100 ppb). The
pool water should be clear, residue and algae free. If stains
are especially heavy on a plaster surface, lower the pH to 6.8
before applying. It is always preferred to bypass all
chlorinators and heaters before adding chemicals, if possible.
NOTE FOR CUSTOMERS WITH COPPER HEAT EXCHANGERS: If no bypass is
available, be careful not to allow your pH levels to drop below
STEP 2—METALTRAP™ STAIN REMOVER: Turn your filter system
off. Add 1 lb. of METALTRAP™ Stain Remover for every 10,000
gallons of water. Walk around the pool perimeter, sprinkling
this powder evenly to distribute throughout. Apply more heavily
over darker stained areas. Do not add any new chlorine to the
water until the complete Stain Reversal Process has been
completed. Leave the filter off for 1 hour.
Turn the filter system back on, leaving the chlorinator and
heaters off and bypassed. Let the filter run continuously for
24-48 hours, or until the stain is completely gone. During this
time, brush the entire surface of the pool and spa at least
twice per day to help remove the stain. NOTE: A combination
brush (part stainless steel and part nylon) is recommended on
plaster pools, and a nylon only brush is recommended for
fiberglass and vinyl liners. After stains are removed, vacuum to
waste any residue, if needed. You may also use a filter aid in
sand and cartridge filters to remove heavy residue.
STEP 3—POOL REFRESH: To remove the newly dissolved metals
from the water, follow immediately with POOL REFRESH A & B. POOL
REFRESH acts similarly to a "floc" agent to safely react with
these dissolved metals, cloud the pool, and enlarge the
particles so they can be trapped in the filter and removed
permanently. You should see the metals brought out of suspension
and cloud the pool within 24 hrs. After the pool is cloudy, add
DE filter-aid powder through your skimmer to increase the
efficiency of your current filter system. Immediately turn the
filters back on and start filtering the metals out continually.
Keep a close eye on your filter pressure at all times and
backwash as needed, adding new DE filter-aid each time. The time
needed for this final cleanout process will vary from pool to
pool depending on the size of the pool, the levels of metal and
staining present in the water, and the efficiency of your
circulation and filtration systems. Typically, this process will
take 2-5 days. (Please see the POOL REFRESH label for complete
STEP 4—REBALANCING WATER CHEMISTRY: Once stains are
completely removed, thoroughly clean the filter to remove any
trapped metals. Before reintroducing chlorine, add 1 quart of
LIQUID METALTRAP™ for every 10,000 gallons of water. LIQUID
METALTRAP™ is designed to safely bond with dissolved metals in
your water, deactivate their staining potential, and keep those
metals safely in suspension in your pool. (Please see the LIQUID
METALTRAP™ label for complete details.)
Gradually bring total chlorine levels to 1.0 ppm over a 3-5 day
period. WARNING: Shocking a pool is never recommended
immediately after a metal stain treatment as it increases the
risk of re-staining. (If algae appears at any time during this
process, use a Poly-60 algaecide as a chlorine shock
alternative.) Gradually bring pH levels up to 7.2. Open bypass.
Turn equipment back on. Continue balancing your water chemistry
STEP 5—FILTER METALS OUT BEFORE ADDING NEW WATER: Always
use a METALTRAP™ Pre-Filter to remove metals from source water
every time you add new water to your pool or spa. Continue with
maintenance levels of LIQUID METALTRAP™ according to its
directions to protect against future staining.
