  • 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.

Such an innovative design. Huge game changer.

Added utility.

Added to medium sponge filter in 20 tall blue dream neocaridina tank. Aesthetically, for me, it's a compromise. You're trading a column of silvery air bubbles for a much taller bright green tube. Yes it blends in with plants, but you will always see it. It doesn't bother me, but something to consider. It definitely adds more flow and the ability to direct it is a real plus. I was able to easily dial it in to a rate that is gentle enough for the shrimp but providing more flow that the traditional airstone. It's definitely quiter than bubbles popping at the surface, but I have yet to see how water level changes with evaporationg influence that, like whether or not it will need frequent adjusting. I'm really hoping that the reduction in bubbling at the surface above the filter is going to slow the growth of algae on my tank lid. And there's always the option to go back to more traditional implementation by taking off the upper tubes and leaving the air collar, or adding back an airstone. I'm impressed with it so far.
