Phosphate remover dosage for pools

Phosphate remover dosage depends on your pool's phosphate level and volume. Generally, use 5 ounces per 10,000 gallons for every 5,000 parts per billion (ppb) of phosphates. For a typical pool with 1,000 ppb phosphates, this equals 1 ounce per 10,000 gallons. Always test water first and follow product instructions.
