• What is Pool Stain
Pool Stain Treat is a sequestrant & a chelator. Those are fancy words for a
metal holding, stain remover and prevention chemical.
• Why do I need a stain
A fact not generally known by the pool business is that all water has
metal in it. We get 25,000 calls per year on staining and over half showed
no metals when tested. Staining is the number 1 problem and it's the hardest
to fix. Algae is easy for us to get rid of.
• Does Pool Stain Treat
remove metals from the water?
A little metal will be removed from the water but no product is effective in
eliminating all metals from the water. Many of our calls are complaints
about competitor's products that didn't work. Since metals come from dust,
rain, fertilizers, city and well water and other chemicals, it's ridiculous to
believe that you don't have metals in your pool. United's position is that
you always treat for metals and that will protect you from a bad surprise.
It's like wearing your seat belt always when you drive.
• How effective is Pool
Pool Stain Treat is the most powerful stain product in the market today. It
is recommended by most of the fiberglass companies, the largest vinyl pool
company (Doughboy) and plasterers from coast to coast. Thousands of pool
professionals use Pool Stain Treat.
• What can I expect from
using Pool Stain Treat?
First, you should know that stain removal is very difficult in many cases.
Our normal dose rate is a 85,000 to 1 dilution. That's like doing the
laundry with a drop of detergent. Your pool may clean-up in hours or take
months to clean-up. Be patient. United makes other products that can
accelerate the cleanup process but unfortunately they are more expensive.
• Is Pool Stain Treat
No! When diluted in the pool water, the oxalic acid in the formula is below
the level of oxalic acid in spinach and rhubarb. We calculated that you
would have to drink over 1900 gallons of pool water to get enough oxalic to
be toxic. Of course, you wouldn't have survived the water. We do have some
competitors trying to scare our customers but that's their fear of a better
• Do I run the pump when I
add Pool Stain Treat?
It doesn't matter whether you run the pump or not. Some people like to dump
the product directly on the stain with the pump off. It's faster and more
dramatic but can cause temporary streaking. Follow the instructions, it's
• Will Pool Stain Treat
affect my pool chemistry?
Yes. The product is acidic and can lower the pH. You may also witness a
temporary loss of chlorine residual. Don't shock. Just gently chlorinate.
Pool Stain Treat is unique in that it performs in any pH range and is not
super susceptible to chlorine damage.
• Do I have to drop my
chlorine or bromine residual before using it?
No. Don't shock the pool and up to 3ppm of oxidizer is OK.
• What is the #1 cause of
After 200,000 calls, United now knows that high oxidizer (chlorine, bromine,
peroxide) is by far the most significant cause of pool/spa staining. As
little as 3ppm is enough to cause staining. Shocking causes levels way above
• My dealer says that I
have to hold my chlorine / bromine residual above 3 ppm. Is this true?
That was before No Mor Problems® was around. United has made high
residuals a thing of the past. As we said before, algae is easy for United.
We've eliminated shocking, also. Remember these are the #1 causes of
staining. With us, a 1 ppm residual is plenty, even in Florida.
• I have clear green
water, is this algae?
NO! That's classic symptoms of metal contamination. The pool is already
trying to stain. When the water turns clear green, it's a sign of lots of
metal and you should put in double the normal dose of United's Pool Stain
Treat to counteract the metal.
• What metals is Pool
Stain Treat good for?
All heavy metals. That includes copper, iron, manganese, silver, and others.
Typical metal colors are:
• green, blue, gray = copper
• brown, gray = silver
• pink, gray, brown = manganese
• brown = iron
• brown (Fiberglass) = iron/copper
• I just plastered my
pool, is Pool Stain Treat the best for it?
Yes! Yes! Yes! For some strange reason, the pool business doesn't relate to
the fact that the best stain removal product should be used as a stain
prevention product. If it's the best for removal, it's the best for
prevention. Stain removal is much tougher than prevention. DON'T SHOCK!
It's good for any just filled pool/spa.
• Is Pool Stain Treat ok
for my pool surface?
Yes. It is used on all pool/spa surfaces. We haven't found a surface that
it can't be used on. Paint and color (marcite) are unique and be sure to
follow the instructions.
