Air collar makes smaller bubbles for improved performance
Easy Flow accessory increases water circulation
Coarse, anti-clogging sponge
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.
This coarse sponge filter is easy to clean and does a great job of filtering my low maintenance tanks. I have them in my 10gallon, 29 gallon and 75 gallon! Got the medium and larger sized sponge filters.

The best sponge filter
I am so happy with the easy flow sponge filter. I've ordered several for myself and convinced a friend to get some too for his tanks.
I love the design and how the curved top helps direct water flow around the aquarium. I love the larger pores in the sponge that help prevent clogs. I love the color that blends in with my aquarium plants. I love the fact that it gives off fine bubbles and is super quiet. And I love the low cost and overall high quality.
I highly recommend this product for anyone thinking about getting a sponge filter.

PERFECT for my 5 gallon tank
I tried this little one in my 2.5 gallon and it fit perfectly. But I’m using it in my 5 gallon. I have to say the size and the flow is just what I was looking for in this tank. I use the flow and not just the bubbles and it definitely makes a huge difference for me personally. It’s a filled planted tank with Java moss. More moss than I’m sure it needs. But I do have some very very amazing guppies that would not do well breeding due to spinal issues in there with some snails. And it works very well thus far. I have the biggest filters in my 20,30and 55 gallon tanks. This one was worth every penny to help filter my 5 gallon and keep it healthy longer. Would highly recommend this one for a 2-5 gallon tank!
