DIY Foam Sheets

A high-quality filtration system is essential for any pond and aquarium to ensure your fish stay healthy. Filter foam sheets are an important part of this as they will contribute to an optimal environment for your fish. Ready to say goodbye to algae and other toxins and contaminants? Learn more about our different filter sheets.

Finest Filters’ foam sheets provide excellent biological and mechanical filtration in both aquarium filters and pond filters. The foam allows bacteria to colonise to break down ammonia and nitrate, whilst also catching particulate waste out of the water. Like the activated carbon sheets below, they are a perfect choice for filters requiring a custom shaped filter pad. Simply cut the foam to size to fit within your external and internal filter. The sheets are also available in coarse and fine grade, and should be used depending on application. 

We also stock activated carbon impregnated foam sheets. These sheets offer excellent chemical filtration in your pond or aquarium, by removing dissolved organic compounds from the water. This filter sheet is large, meaning you can cut it into several pads to fit your filter, depending on the model. Activated carbon is proven to improve the water quality by removing odors, discolouration, and other contaminants from the water by trapping the particles in the foam sheet.

Ready to keep your ecosystem in perfect condition? Browse our range of filter foam sheets below. The filter foam we offer is completely aquatic safe, and is not treated with any chemicals, so it is guaranteed to be safe for your fish. We have been using this in our tanks for many years with great results.
