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.

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😉

Much better design than the original sponge filter.
No air stone needed unless you prefer to use one.

Much better flow rate.
Love it.

Good Product

This product is as advertised and effective. Better to buy from one of our guys than from people we don't know on the other side of the world. We want our guys to be suucesful because they know us and our fish.

Simple and looks good

Simple and I love the green tube. Easier to blend in my small tank! Good, slower water current for sensitive fish like Bettas. Thank you!

Easy to Install and Maintain and Effective

I have acquired a couple of these easy flow sponge filters for our two 20 Gallon aquariums and they work great! Perhaps less effective than an HOB or canister filter system, but very easy to maintain.
