How many sponges can 1 co op air pump run.

Like the title says do you think on co op air pump could run 3 small co op sponge filters in 2 ten gal tanks side by side and get enough flow?

It's doable if you are referring to the black Aquarium Co-Op Air Pump (with backup battery) and not the nano USB pump. I have mine attached to a gang valve, and it is supplying air to three tanks with small and nano sponge filters (one in a 10 gallon, one in a mini tub/pond...about the same depth as a 10 gallon, maybe a bit deeper), and a nano 4 gallon tank. You will have to adjust the valves to get the flow equal to all three sponges. The flow that I am getting to all 3 is just right.

Get I already have the gang valve. I want to supply to  shrimp tank and back up filter for my guppy grow out tank. Yes the black co op pump. Thanks Zenzo I appreciate it

I am running two medium sponge filters with one USB nano pump. Although it does work, it's just not enough flow. I just ordered another USB so that I can run each sponge with its own pump. I don't know what I was thinking except to say I hoped it would work with just one. Wrong.
