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.

Best sponge filler!!

Doesn’t get clogged and stops working after a week like the amazon one’s super simple to set with nice flow and affordable

Really elevated my tank circulation

I love this filter. It has done wonders for my tank and keeps the water moving without overwhelming my fish. Highly recommend this to bring movement and oxygen into the tank.

Wayyy Easy Flow

I have been a fan follower and customer for years now. I’ve Always been 100% satisfied. I had to write a review for this sponge filter. From set up to placement only took a couple of minutes. My shrimp were immediately like “Heyy check this out!” LoL
Thank you Aquarium Co-Op team for all the help. You answered my product question email expeditiously so I could place my order. You’ve provided countless videos. I’ve watched most. I stumbled across Cory years ago. He bridged my love of plants and being an Aquarist.

Minor Noise Complaints

I used to use the sponge filter from Hikari which works fine and just wanted to give a try on this one. It is unexpected that this sponge filter slightly nosier than my Hikari sponge filter.

Hikari filter doesn’t need the air stone to make the bubble smaller and reduce the bubble noise. But this product making minor buzzing/crackly noise from the air collar. I can make the noise less by taking off the pipe on the top, just using the air collar.

Noise itself is minor issue, I don’t notice during the day time while other noise, TV, music or people talking are present. Only time it bothers me just at night when I’m alone reading/studying. Wish I have the choice to buy without airflow kit, but overall very satisfied my purchase. Additionally I’m proud of myself that I invested on small business rather than franchises or Amazon😉

Sponge filter

It works but bubbles coming out the side of tube. Is that normal ? Overall good product .

Love this filter!

Easy flow sponge filter

Works good but it needs enough air pressure to get through those tiny holes in the collar!

Updated review

Just received the small filter which is supposed to fit a 5 gal tank (mine is 6) and it’s waaaayyy too big. Will cost me more to return so I’ll keep it for potentially a future tank. Sticking with my HOB for now. NOTE: everything else I’ve ordered from this site is great 🐠

Update: customer service immediately contacted me and discussed ways to work with this filter and assured me sizing is correct. Without my asking, nor with any expectations whatsoever, Customer Service took care of me. Based on this alone, I have given the product 5 stars. In retrospect, I should have contacted AC with questions before purchasing but that is on me. Lesson learned and I will continue to buy from this site.

great product. love it

if you haven't got one of these, you're missing iut. great product

Great Filter!

Great filter! Did what it said it would do, simple design but works great! Plastic tubing felt a little cheap, but I expected that. For the price this is the best bang for the buck! Especially if a bunch are needed for a fish room! Thanks Coop! Excellent product!
