Foam Sheet for Aquarium Fish Tank Filter Pond Sponge 18"x12"x2" Coarse 25ppi or Fine 40ppi (Fine 40ppi)

Our foam sheets provides excellent biological and mechanical filtration in aquarium and pond filters alike. The foam allows beneficial bacteria to colonise to break down ammonia and nitrate, whilst also catching particulate waste out of the water. These foam sheets measure 18 inch x 12 inch x 2 inch thick. These foams are ideal for Hambug matten filters, and we have them in a choice of foam density: Coarse Foam (25ppi) or Fine Foam (40ppi). Please select the required specification from the drop down menu when ordering. 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. This is suitable for all makes and models of aquarium and pond filter - simply cut to size.
