I broke down my 29 gallon, and did a thorough cleaning because bryopsis got a good foothold. I had just got this tank all set the way that I wanted it with all acros, so had to shift it all to my frag tank during the cleanup. I decided to go back with a bare bottom, and wanted good flow around the rocks with no dead spots in the flow. I came up with this idea, and thought that I would share. Thanks for looking!
