Sponge filters offer reliability and hassle-free operation. With no moving parts, all you need is an air pump with some airline tubing, and you've got a filter that is fully contained within your aquarium. Sponge filters are completely reusable, don't need any replacement cartridges, and last for several years. Plus, they are gentle enough for betta fish, baby fry, shrimp, and other slow-moving species. Trusted by fish farms and wholesalers, they are an excellent choice for aquarium filtration that you can set and forget.

Increase Circulation in Your Aquarium

The Easy Flow Sponge Filter 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.

Adjustable Height for Different Tank Sizes

The Easy Flow curved uplift tube has an adjustable height, allowing you to use it for both small and big tanks. Use our sizing chart to find the perfect sponge filter for your aquarium. Ideally, the tube opening should sit 1/3 out of the water and 2/3 in the water.

No Air Stone Needed

Our air collar replaces the need for an air stone. Uniform bubbles with the airline tubing 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 or toothbrush 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.

Extra Heavy Base

Our extra heavy weighted base helps the sponge filter sinks right away. Give the sponge a squeeze when you put it in the water to remove any extra air. The heavy base also helps it stay in place when fish might try and move it.

Coarse Sponge

Our coarse sponge allows for extra time between cleaning. It's also able to hold more debris. This is a great place for baby shrimp and fry to forage for food. Baby shrimp even use the sponge as a cave system to hide from fish that may try to eat them while growing. We recommend servicing sponge filters once a month.

Cleaning Is Easy

We recommend cleaning your sponge filter once a month. Removing the debris from the sponge ensures it won't clog up unexpectedly. While our sponge filters can often go many months between service, it's a best practice to service monthly. Also, clean the air collar with a small pipe brush or toothbrush to remove any debris buildup.

Bonus Tip: Pour the brown water on your houseplants to make them very happy.

Great sponge filter

Great sponge filter that was easy to set up. No issues with delivery.

Best sponge filter

After two weeks of running the aquarium co op filter it still looks new and the water is crystal clear. Thank you aquarium co op!!! And thank you Cory!

Love these!

So I purchased these for two of my tanks. They look great and being weighed down made them easy to place after rinsing them out and assembling them. They work great and they definitely help with circulation. Highly recommend them.

Excellent for Scrubbing Water in 65G Tank

I was very excited to try out this new fine pore sponge filter attached to a powerhead to see if I could scrub the water in my 65 gallon tank and make it extra crystal clear. GREAT SUCCESS!! Absolutely would recommend this sponge filter for that purpose!

Love This Product In Black!

I have run the green coarse sponges for years and have really enjoyed them. I feel that the black version looks great on tanks with black backgrounds. The included Easy flow kit makes the filters very quiet as well.

Great Product! Glad they came out with the Fine Sponge as well!

I have run the green coarse sponges for years and have really enjoyed them. I feel that the black version looks great on tanks with black backgrounds. I have used the fine sponges in the place of box filter in some of my mulmier tanks. The included Easy flow kit makes the filters very quiet as well.

Best sponge filter I’ve used

This is the best sponge filter I have used. Changed over all old sponge filters to these. Very pleased with the easy flow uplift! Highly recommended

Functional & Easy to Clean

I really like these sponge filters. I do wish that we could purchase additional sponges without having to buy the entire kit (base & tubing).
These still work when they haven't been cleaned in a while, which is great, and they are very satisfying to clean (also very gross when you think about it).

Love!
