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.
Works great, amazing upgrade for the sponge filter!!!

Fintastic upgrade
This is a must have to upgrade any of your existing coop sponge filters. They can be cut down and customized for any tank

Breathed new life into old filters!
I hate to throw things away -- these upgrade tubes can be used to replace the tubes in certain other well-known brand of fishroom sponge filters whose uplift tubes tend to break over time! Breathed new life into old equipment! Also found it works with virtually every small powerhead I own... yet more old gear saved from the dump by this inexpensive kit.

Great idea but my hard water says no
I was very excited about the flow deflection that the design provides, however mine have clogged due to the liquid rocks we call water in Ohio. Back to the ziss airstones.

Easy Flow, Indeed!
At first I didn't understand how this worked, but after watching a YouTube video with Irene, it all made sense. I no longer use a HOB filter, so I angle this flow toward a basket hanging on the tank with filter floss inside. Works like a charm. Creates surface flow and the floss catches all the muck.

Filter upgrade kit
Perfect addition to the sponge filter for easy use and to add some flow. My fish are digging it.
