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.

To optimize the sponge filter’s performance, we’ve included an air collar that replaces the need for an air stone and minimizes bubbles coming out of the side of the sponge. The air collar produces smaller bubbles that lessen noise and create more continuous current. If you need greater water circulation, use the included Easy Flow accessory that curves the uplift tube so that water flows out of the sponge filter horizontally across the water surface and around the aquarium.

The Aquarium Co-Op sponge filter is designed using coarse foam so that it can go many weeks between cleanings. The weighted base will immediately sink to the bottom of your aquarium, so no more floating up after a water change or initial installation. Also, the green plastic helps hide algae and blend in with your live aquarium plants.

I love the new kit I dont personally mind the extra space it takes compared to the older models However it is much more effective for your tank and my fish are happy

Works well, ain't nuthin to it

Seems pretty strudy and I like the colors. My only complaint is that if you are using it with an airstone inside and the line gets brittle, when you snap back the upper and lower halves together the line inside will come loose, and then you have to start over... I just got one of the large filters with the easy flow kit, and it's pretty awesome. Just the right amount of flow in my 50 gal. along with the Aquaclear 50, and not needing an airstone is really convienent. The airline holders work great, and the adjustable height is just the right tightness so that it will hold while being easily adjustable.
