Administrators Cory Posted October 11, 2020 Administrators Share Posted October 11, 2020 I'd use two "small" size sponge filters, 2 usb air pumps. If you hang the air pumps above the tank, no check valves needed. Don't forget the airstones to put inside. Link to comment Share on other sites More sharing options...
