PR-10000, Phosphate Remover Concentrate, for Swimming Pools, 1 Gal - 2 Pack ORE-50-227-2

use this for my pool company. since all the price increases, they are now a competitor.

the phosphate level in my pool was >600 ppb (very high) and 2 doses of this product over 5 days reduced it to 110 ppb, which is an acceptable level. it clouds your pool water, but it is temporary and it's still safe to swim.

Very high quality works great.

There was a marked decrease in algae in my pool because the algae is not getting the phosphates it needs to live and reproduce, so it dies. I was using many bottles of algaecide every year to try to keep the pool water clear. My pool would turn green very quickly after a good rain or just from sunny skies over a week's time. Reducing the phosphates in the pool water has reduced the number of times I have to treat it for algae from every week to less than once a month, and even then the treatments are usually just a few ounces of PR-10000 and perhaps a few ounces of algaecide to keep it clear. Used according to label directions.

I've bought this product before. Great product at a great price.

Used for 2 years.... keeps pool clean and clear....I use weekly.... keeps me from having problems.

Excelente producto !

Used to prevent algae. Followed instructions and it’s working extremely well! Very pricey but so far it is worth it.
