    Direct replacement. We clean them 3 or 4 times then we replace them with these. Makes cleaning the tank and filter a lot faster.

    Good. Buy it for your fish and they will be happy. Good for filter too. Put 2 pads together for better filtering

    Ive used several different filter systems on my various aquariums. I love this underwater one the most. No constant running water. It keeps the tank clean and the filter elements last a long time.

    Ive used these filters for years on my aquarium. I used to pay so much more when I bought them at the pet store. Now I cant even find them in the pet store. So glad I found a reasonably priced source.

    This review is for the foam pad component to the Fluval U3 reptile filter. We have had an aquatic turtle for aost 21 years. We have tried other filters and were quite happy with them. When they went out of business, we decided to try Fluval U3; we are beyond delighted with this system. The water is always clear, no algae, no smell, and it is quiet. Highly recommend Fluval U3; and its components of which this foam pad is one. Of

Fluval Poly/Carbon Cartridges features two sides for effective chemical filtration, the crucial second stage in the filtration process. The polyester filter pad side filters out fine debris and contaminants. The carbon side filters out harmful liquid substances, colorants and odors. The Fluval Poly/Carbon Cartridge works in part with the Fluval Filter Foam Pad to help keep your aquarium healthy and clean.
