  • Not compatible with Nano sponge filters sold BEFORE December, 2023
  • Increases flow in the aquarium
  • Comes with an air collar to make smaller bubbles
  • Attaches to Aquarium Co-Op sponge filters 

If you need greater water circulation from your Aquarium Co-Op sponge filter, try the Easy Flow accessory. By lengthening and curving the uplift tube, water flows out of the sponge filter horizontally across the water surface, increasing the current in the fish tank.

The Easy Flow sponge filter upgrade kit also comes with an air collar that attaches to the base of the uplift tube. The airline tubing connects to this air collar, which creates smaller bubbles much like an air stone. These little bubbles help to create more continuous flow and optimize the sponge filter's performance.

If you already own an Aquarium Co-Op sponge filter, use the Easy Flow attachments to improve circulation in your tanks. It works with our small, medium, and large sponge filters, as well as nano sponge filters made after 2023.

Easy Flow Sponge Filter Upgrade Kit

I have been using COOP products for several years now. It just made sense to give this upgrade a try. Besides the gentle but increased flow this provides I am not going to have to clean mineral deposits from the inside of the tank lid near as often! The tank I used this on is in my bedroom and it has reduced the noise as well. I really appreciate the fact that they make and improve products for the hobbyist based on what they learn from their own tanks. Very happy with Cory, the COOP and this product. As long as I have tanks I will be a customer.

Best bang for $

Simple, effective, tried and true filter. Thousands of aquarium store owners can’t be wrong. Upgrade makes it great for simulating current as well.

Convenient upgrade for legacy sponge filters

I'd recommend this upgrade to anyone running the legacy models of Aquarium Coop's sponge filters. My favorite part is the air collar with the side mounted airline. It makes cleaning much easier compared to the traditional centerline airstone which can get detached when cleaning the filter. Some additional notes:
-I currently run a Small sponge filter with the easy flow upgrade kit in a 10 gallon tank. I have used the upgrade kit for a few weeks now
-Personally, the air collar sounds *very slightly* louder than the old Ziss airstone, but the airflow and bubbles are a lot better with no bubbles coming through the sponge, so I don't mind the difference.
-I had to trim a bit of the old airline tubing (which had hardened) to properly connect it to the new air collar--Not a negative, but just a heads-up for others.
-I have not used the curved easy-flow component yet as I wanted the gentler flow up the straight uplift tube for the time being, but I will experiment with it soon.
Overall 5/5
