Cobalt powerhead

I think this product works well it seems to move the water around my 75 gallon tank well I like the fact that you do not have to hook it up to a bubbler because it comes with an air release tube the package arrived in great condition and the product was brand new thank you again aquarium Co-op great job

Versatile reliable

I am using this powered in a large cichlid tank. I have it running a diy sponge filter. Works great picks up a lot of fines from the water and adds just the right amount of circulation. Very strong and reliable.
