MickS77 Posted October 10, 2020 Share Posted October 10, 2020 I'm going out of town for the night tomorrow and plan on visiting some LFS. If they have something I can't leave without I wanted to give them a better chance to make it home. I made these using a small bag of biomedia from an established tank. I used the Aquarium Co-op Nano USB pump, Airline, and Ziss Airstone. I ran the airline through a small terracotta pot and reattached the Airstone. The weight of pot helps keep it all down. It works pretty good like an old box filter. 5 Link to comment Share on other sites More sharing options...
