• 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.

Easy setup. Airline tubing, air pump, check valve and an airstone. Put it all together and plop the sponge filter into your tank. The bacteria will be off to the denitrifying races!

Love these!

All of my tanks have sponge filters. So easy and reusable so I'm not throwing away used filters all the time.
