Hydro Sponge Filter
by Joe Hildreth
I have tried every type of filter available and these foam filters are the best. They are very easy to use and maintain. The results are excellent.

Super easy to set up & use. Very effective! For the money, sponge filters are the way to go!
Great sponge filter

Great filter, duraable sponge on the pro models, stackable. Works great witha powerhead. You can put multiples of these sponges together to customize the final size. Breaks apart for easy cleaning.
