Natural Chemistry PHOSfloc For Pools with Extremely High Phosphate Levels.
Initial dosing with PHOSfloc will drop phosphate ppb to more manageable levels for use of PHOSfree and Pool Perfect+Phosfree. Clear, Perfect Water...Unconditionally Guaranteed! PHOSfloc reduces high phosphate levels to more manageable levels, inexpensively. One bottle of PHOSfloc will reduce 4,000 ppb of phosphates to approximately 600ppb in a 10,000 gallon pool. At this point phosphate levels can be reduced to near zero levels with regular PHOSfree or Pool Magic+PHOSfree. Note: PHOSfloc must be vacuumed to waste or removed from the pool with a separate vacuum pump. PH must be adjusted to 7.2 before applying. Follow directions for product application closely.
