PR-10,000 is a highly concentrated, all-natural rare earth phosphate remover. It is formulated to react with phosphates in water, allowing for them to be removed from solution. It reacts with all known types of phosphates on contact, and hardens them into a fine precipitate, which falls out of solution. The inert phosphates then floc out, to be vacuumed or filtered out of the pool. PR-10,000 causes cloudiness, which can last anywhere from a few hours to a few days. Use as needed, and do not exceed the recommended dosage unless otherwise specified (see below).
1oz per 1,000 Gallons – Treat no more than once a week, until phosphates read .3ppm or lower.
