POLY-FILTER INSTALLATION:

A) Conventional Power Filters

Place the POLY-FILTER on the bottom plate or surface of the power filter. It can be covered with regular polyester pads and/or gravel. DO NOT COMPLETELY COVER THE BOTTOM PLATE WITH THE POLY-FILTER. The POLY-FILTER should have water flow over and around it to function effectively.

B) Plastic Undergravel Filters

Push aside gravel covering the filter plate and place the POLY-FILTER on top of the undergravel filter plate. Cover both the undergravel filter and the POLY-FILTER with gravel.

C) Canister-Type Power Filters

Place conventional filtration materials on the bottom of the canister. Then place several POLY-FILTERS in layers on top of these materials.

Do not install the POLY-FILTER so as to restrict water flow. It is essential to have water flow over and around the POLY-FILTER. You may trim the POLY-FILTER with a scissors to fit any situation without losing any of its effectiveness. Finally, cover the POLY-FILTER with a layer of material, the more porous the better, or use non-rusting screen material to prevent the POLY-FILTER from floating to the surface.
