  • 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.

Fantastic affordable gear

I use these for my porch ponds (30g or less) and a couple of tanks.
It has enough ummpphh to create a little cascade in my "porch ponds".
Love it👍👍

Easy Flow Is A Major Upgrade

I purchased 4 Easy Flow's two for my shorter 40 gallon, and two for my 120 gallon. The directional flow, the removal of the pain in the butt/forever needing adjustment airstone, and the adjustable heights with the side adapters for the air tubing are great. Plus the kit is cheap.

Easy flow

This an amazing upgrade for my sponge filters. It reminds me of the undergravel filters back in my early days of fish keeping.

easily adjustable height

It was easy to customize the height to fit my aquarium. I think the fish enjoy the new water flow pattern.
