The Water TechniX Floc is a powerful pool flocculant that's guaranteed to leave you with crystal clear waters after treatment. Your sand filters can only filter down to 20 microns, this leaves the tiniest particles to go through and once enough particles have gathered in your pool, the water will appear cloudy which is why a flocculant like the Water TechniX Floc Granules is needed. High potency granular flocculent for muddy, algae infested or severely cloudy pools. For use in pools where the floor of the pool can no longer be seen due to suspended particles or algae in the water. Ideally used in combination with a chlorine Shock to quickly fix very green or very muddy pools.
