theotheragentm Posted July 26, 2021 Share Posted July 26, 2021 I have my goldfish barrel clocking in at approximately 100 gallons. It does fine with no filtration as it's heavily planted with water lilies. Currently it has a solar-powered air stone, which runs 8-10 hours a day. I was thinking of trying to build some mechanical filtration with more flow than sponge filter could provide. Does anyone have a recommendation for a submersible solar pump? I wouldn't need the typical turnover rate people look for in a filter, so I'm thinking I could go with a smaller pump/panel. Link to comment Share on other sites More sharing options...
