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.

Scratch and Dent Black Easy Flow Sponge Filter (fine) - Aquarium Co - Op

1

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.

2

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.

3

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.

4

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.

5

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.

6

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.

7

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 filter, love the color. Nano has some kinks to work through

Overall, these are the best sponge filters on the market. Love the new black color, they assemble easily, and the flow they create is awesome.
After owning ~15 of these, I’ve run into only 2 problems. 1) the ring where the air is released clogged faster than i would’ve hoped. Maybe this has to do with my water chemistry, I honestly couldn’t say. But I was a little disappointed that it didn’t last as long as I thought it should. And 2) the uplift tube on the nano seems to not be as good of a fit as the others. Specifically, the connection point between the straight and curved pieces of the uplift tube leaks a small but substantial amount of air. While this is a small inconvenience, it slows the flow coming out of the end of the tube significantly, which negates the whole flow aspect of this filter. I’ve tried swapping parts with some of the extra pieces from other filters, and haven’t been able to solve the issue, so I think it’s the connector between the tubes having too much tolerance. I’ve only owned one nano filter, so could just be a one-off.
Despite these two issues, I’ll happily buy more of these if I needed more sponge filters. They are the best on the market!

Great Filter

Well made & very thorough cleaning of my tank. Highly recommend.

Very easy to find what you need . I have never tried to order an item only to find that was out of stock. Great job Aquarium Co-Op

So far it has been an excellent experience ordering from aquarium co op. Fast shipping, and everything as described on the website. I just hooked up this sponge filter and the results after running for 30 min is quite an improvement. I highly recommend these guys!!

perfect size and coarseness

The website is super intuitive, the products are always top-notch well thought out and extremely well designed. It's always really gratifying to see how many YouTubers I respect in the hobby, use aquarium co-op products and have done for quite some time.
