Aquarium Co-Op Power Head

It works great for large tanks, but for anything nano (less than 20gal) it's overkill on the flow. I wish I could adjust the rate in half to make it more suitable for my slow fish. But if you have fish that love fast water, this is perfect. This is great for tossing my marimo moss balls around too. I'll have to take if off because it'll demolish my floating plants, but I'll put in a different tank instead :)

After trying out 2 of these power heads for nearly 3 months, I must say they are definitely worth the value and I know I would pay more than $20. The outflow nozzle that can be moved side-to-side and extra-long cord are perks I wouldn't expect to see at this price. I recommend giving it a try. Their customer service is second to none if it doesn't work out.

For anyone concerned about the noise level, in my opinion, it comes down to how sensitive you are to noise. Compared to an air conditioner, refrigerator, air purifier, running water, etc., this is definitely quiet. However, If I am near my aquarium with absolutely no other noise, it surprisingly does not run on magic and has a small motor that I can hear mildly humming away. I've gotten used to it in my 22 gallon long that I work beside. The added flow has been so beneficial to my plants and fish that I can't go back to only air-driven sponge filters.

(For hypersensitive people, I recommend getting a couple of the mini USB air pumps and replacing them when the diaphragm starts to wear out. They are incredibly quiet!)

To summarize, it's been a good purchase. 9/10 because they couldn't make it run on magic. ;)

Great option to place this on the sponge filter. Provides nice flow and filtration.

I love that it hooks up to the sponge filters to draw water through. My fish and shrimp on my river tank love the movement it makes. Aquarium co-op items are the best!

I have this pump in my 40 breeder hooked up with a mini sponge filter for added filtration and I really love it!

This power head keeps the water moving in my aquarium so well. Paired with the easy flow sponge filter, it's perfect.

Aquarium Co-Op Power Head

Built really well. Extra long power cord so there's always an outlet in reach and easily out performs my aquaclear 20...

I purchased multiple. I use these for a lot of tasks (on sponge filter, to increase flow, for utility pump). I appreciate their relatively simplistic design with fewer potential modes of failure. Note that they do not fit on most undergravel filters without finagling or 3d printed parts. The long cord is especially useful. The flow is not adjustable, but this can be macgyvered to some degree. The improvement that I would find most useful is if the outflow was barbed to better secure a hose/tubing when I use it as a utility pump for water changes or with an overhead sump.

A bit larger than I was expecting but it works well in my 60 gal
