IPG Phos Defence is the best and safest phosphate remover on the market. Phosphates are one of the biggest nutrients causing algae to grow. Often phosphate enters pool water from sunscreen, rain runoff, and fertilizer.
IPG Phos Defence is an eco-friendly product. The best part is, due to its natural formula, there is no waiting period after usage.
We recommend, for optimal results, to use IPD Phos Defence in conjunction with a natural clarifier. An entire bottle of IPG Phos Defence 1L is able to remove 3,000ppb of phosphates per 80,000L of pool water.
