- 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.
Have hard water works great for awhile then clogs up
I am very happy with my sponge filters. It’s not been very long but every great breeder I meet uses them exclusively. They are so much easier.
I actually purchased these Sponge Filter Upgrade Kits to upgrade a bunch of older sponge filters from a competitor brand. They're a little tight, but they do fit! I highly recommend.
I got this for my 55g that I set up to mimic a stream sort of look. As if looking from the center of the stream at one of the banks. So I wanted flow going along in the front. This is working perfect and I love it! The fish seem to love playing in the current too!
First time using sponge filter, I am very impressed.
These are really great the added flow is very useful for many things. They also fit well on black base sponge filters. It is much better not to have to attach an air stone and still get the finer bubbles.
The Easy Flow is an amazing product. This will enhance any sponge filter. They even work well for Matten filters. The amount of water movement you get from these is amazing. They also move more water with less air, For those of us who run many tanks on a central air system, this will allow you to have more filters with less air, in my experience. I run a small aquatic business and we run these in every tank!
Upgrade kit came well packaged and is straight forward to use. It added and improved flow to surface water. I really enjoy the product and will buy again.
Gave some flow for my planted tank
