I was just curious about something? I was at the local fish store the other day and noticed in their tanks they had a sponge filter in the middle of the tank with an airling running into it? I saw NO other type of filtration on the tanks other than these setups?
How do they work? Are they efficient? Can you make them?
I am thinking if they do work, for a fry tank maybe? That way you can't suck any up in the intake of a powerfilter? Fry that is.....
Thanks for the info???
