Natural Chemistry's Phosfloc provides pool owners with a way to combat extremely high levels of phosphates in their pools which other phosphate-removers are unable to remove. Using this powerful treatment, phosphate levels can be drastically cut down to manageable levels, allowing other pool products to become effective again. To ensure maximum efficiency of Phosfloc, you should adjust pool pH to as close to 7.2 as possible before application. This treatment requires pools to be able to vacuum to waste or removed with a separate vacuum pump to be properly cleaned up.
