  • Coarse Sponge (20ppi)
  • Green Plastic
  • Sinks right away
  • Can install an air stone inside

It's finally here! Our very own sponge filter. Having used sponge filters for over a decade, I've grown to love them and often dreamed about how I would improve them. We started out by using a coarse foam so it is easier to clean and won't get clogged up with debris it collects. It also sinks the first time! No longer do you have to keep squeezing to get the air out and keep it sunk. Next we made the plastic green. This blends into a planted aquarium and hides green algae that grows. Lastly we designed it so you can install an air stone inside. This helps quiet the sponge filter and give it an even up flow pattern.

Best Buy!

Sorry, I put the fish food review in wrong place. As for the filters bought 3 & they work great. Don't think I will use the standard sponge filter again.

Large filter

Ordered two of the large filters to check them out and compare to my existing ones. Definitely like these better and the green helps blend in a bit with planted tanks
