Hey guys I grabbed a sponge filter to handle the bio filtration on my new grow out tank with a small HOB running strictly for mechanical. How small of an air pump can I run on the sponge being that all I need it for is aerating bacteria? It's in my office and the airpump thats on there is driving me crazy after the first day. I want to run something as small as a whisper 10 if that's enough.
