ViaAqua Aquarium Bio Sponge Filter Media Pad, 23.6" x 17" x 2", Open Cell Foam Cut-to-fit Matten Filter Fish Tank Sump Divider

Works great

Like the thickness, easy to cut to size. Value for the money.

Easy to cut and clean. Holds lots of beneficial bacteria

This is a great product. It is everything is should be and has proved also to be durable and long-lasting. Easy to clean, with a very functional thinckness. My only complaint is price. It should be lower, as it is a bit expensive as compared to similar products. On the alternative, if the seller is not willing to lower the price, then a bigger pad for the same price would make customers very happy. All thinsgs considered I highly recommend this product.

This is great. The filter replacement for my petsafe drinkwell cost the same as this whole filter did. I just cut with kitchen scisors a copy I will get like 30 out of this sheet. Saves me 30x the cost of buying the same from drinkwell.

I replaced the OEM filter media in our Big Dog PetSafe water fountain, this does a nice job keeping the pump from getting clogged. It also seems to keep the algae down a bit. I have enough to last for many years, probably longer than the plastic that the fountain was made from. I would imagine this would be good for other uses where you don't need fine filtration.

A lot of people use upholstery foam for costumes, but this is firm and helps with heating issues.

Works as an aquarium filter and can be easily cut to fit. A little expensive for what it is.
