When combined with "Filter Wadding," high-quality sheet foam may be cut to any size and provides a big, affordable filter surface for sparkling water.
There are three-piece foam packs that can fit almost all sizes and types of biological box filters.
Each pack has three types of foam: fine, medium, and coarse.
Various Foam Sizes
Foam Sets Measuring 11" x 17," 18" x 25," and 21" x 42"
This will ensure that the dimples in the foam capture and trap the waste particles. Place the foams in your filter in the following order: coarse, medium, and fine.
