Shark Pond Foam 17"x11" M-F Egg Box

The Eggbox (profiled) Foam Sets are high quality sheet foam, giving a large economical filter surface and can be used in conjunction with filter wadding for sparkling water quality.

These 3-piece foam packs are available to fit virtually all types and sizes of biological box filters. Normally supplied in three different grades of dimpled foam per set.

It is recommended that the coarse foam is positioned on top (Black), the medium foam is positioned in the middle (Blue) and the fine foam (Green) is positioned at the bottom. This will allow for maximum particle removal and cleaner, clearer water.
