DIY Fine Foam Sheet (18" x 12")

Finest-Filters fine foam provides excellent biological and mechanical filtration in aquarium and pond filters alike. The beige fine foam allows bacteria to colonise, and break down ammonia, whilst also catching particulate waste out of the water. This sheet is large - meaning you can cut several pads to fit your filter - depending on model.

Our filter foam is totally aquatic safe, and is not treated with any chemicals, so it is guaranteed to not harm your fish. We have been using this in our tanks for many years with great results.
