Easy Flow Sponge Filter Upgrade Kit

• Not compatible with Nano sponge filters sold BEFORE December 2023
  
• Increases flow in the aquarium
  
• Comes with an air collar to make smaller bubbles

If you already own an Aquarium Co-Op sponge filter but wish you had greater water circulation, get the Easy Flow Upgrade Kit. By lengthening and curving the uplift tube, water flows out of the sponge filter horizontally across the water surface, increasing the current and oxygenation in the fish tank. No need for an air stone because it also comes with an air collar that creates smaller bubbles for quieter sound and optimized sponge filter performance. It works with the Aquarium Co-Op small, medium, and large sponge filters, as well as our nano sponge filters made after 2023.

Tips and Tricks:

— When cleaning your sponge filter, don't forget to scrub the air collar and clear out any debris or algae that has covered the holes.
