Jolly Gel is a fantastic gel based clarifier and flocculent used to remove the finest particles of dust and algae spores from the water passing through your filter.
To use just place the gel cube in the pump or strainer basket. The Jolly Gel slowly dissolves as the water passes over it on its journey to the filter. The Jolly Gel places a porous, clear membrane screen over the filter media, and penetrates the bed to an average depth of some 15cm (6 Inches). The membrane allows the sand to trap smaller particles than usual, resulting in fantastic clear water.
Jolly Gel is also proven to remove phosphates from your pool water.
4 x 70g Jolly Gel blocks per pack.
One Jolly Gel block can treat up to 12,500 gallons of water (56,000 litres)
