- 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.

Customer Reviews
I have been using the Easy Flow Upgrade Kit for a little under a year now and am very happy with the flow they provide. The ability to adjust the length of the uplift tubing makes this a great product in my fish room for both my larger (largest 245 gallon) and smaller aquariums (smallest 20 gallon high). I would recommend upgrading your current sponge filters.
Very easy to assemble/adjust and create great flow. Only issue I have is being too tall for smaller aquariums. I have to cut some of the parts down to fit under lids. They require some regular cleaning if you have hard water. I made some parts to hook up to my under gravel filters and they work way better than the old air stones did. Next is to hang them through some matten filters.
Works great definitely seems like better flow I love that the coop made the upgrade an option instead of having to buy all new filters
Awesome upgrade and great value. The air collar alone is worth the money. It makes a significant difference in flow in the aquarium.
Great product. Love the flow
Highly recommend. I’ve noticed better filtration from my sponge filters since adding the upgrade kit.
Never had a sponge filter when I was a kid. I wish we had! Excellent filter. I will be buying more!
I believe all tanks require some current/water circulation, like all bodies of water in nature experience. This is a simple way to provide it using your existing filter as a base. It works like a power head without the bulk or additional electricity demand. Love it!
I use this to supplement a Fluval 307 cannister filter. It works great. My only wish was that it came in black black, but that is simply because I have a black background (and easily remedied with some black Plasti-Dip).
My second order and couldn't be happier. Fast delivery was a must/it happened, thank you.
I have 5 tanks set-up and have gone to using only Easy Flow Sponge Filters. These have improved each aquariums along with the fish immensely. I have clear water until I clean about every 2 weeks.
