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.
Increase Circulation in Your Aquarium
The Easy Flow Sponge Filter Upgrade Kit creates a directional current in your aquarium. This is good for delivering nutrients to plants and sweeping debris back to the filter. It also benefits fish by giving them something to swim against.
No Air Stone Needed
Our air collar replaces the need for an air stone. Uniform bubbles with the airline on the outside delivers better even flow, which increases the flow rate and reduces noise. No more glug, glug, glug sound. Use a small pipe brush to clean the collar during monthly maintenance.
Blends in With Plants
The green color blends in with plants and helps hide any green algae on the tubing. But it's still transparent enough to see the uniform flow and ensure your filter is working properly at a glance.
Been able to adapt these to the various heights of my tanks. Love the increased surface movement.

Didn’t know what I was missing…
The flow and filtration efficiency is hands down the best I’ve had. I’m definitely replacing all my sponge filters with these! Great job aquarium co-op!

Answer to many prayers.
I've used the stone fore a few years now and I hated having to clean it constantly. This thing is quieter than the sone ever was and works great.

Easy Flow Sponge Filter Upgrade Kit
Aquarium Co-op is absolutely tops in my book! The items were packed securely, they arrived in a timely manner, which is really saying something for someone who lives in Alaska! I really appreciated the email updates; I could see where the shipment was and didn't have to go to different sites and set up some new password.
The Easy Flow Sponge Filter Upgrade Kit works like a charm, just what I needed! The filter and upgrade kit was simple to set up and I couldn't be happier with the results. The water in my tank is clear without needing to use any chemicals or additives. In closing, I would be remiss if I didn't mention the extremely reasonable price. No need for boxes of replacement filters, carbon, or other filtering agents. I will recommend you to anyone who has an interest in aquariums, and any future aquarium needs I may have, I'll check your site first!
