Jolly Gel, which works with sand, Zeoclere and glass filter media, are small translucent 5cm x 5cm cubes which are placed in the pump (not the skimmer). The cubes dissolve slowly as water passes over them on the journey to the filter. Jolly Gel places a porous, clear glutinous membrane screen over the filter media, and penetrates the bed to an average depth of some 15cm (6”). The glutinous structure will remove the finest particles of dust along with algae spores.

During backwashing the filter, as the bed lifts, the Jolly Gel formulation washes the collected debris and spores to waste.

When using Jolly Gel for the first time, it is important that the user observes the pressure reading within the first six hours, or dependent on the filter cycle. The product has a far faster collection capability than all known flocculents, so the user may be unaware that the pressure in the filter could build unnoticed. Once the water has been cleaned by Jolly Gel, normal maintenance can be resumed.

Jolly Gel has not been formulated for cartridge and DE filters and should not be used in these filters.
