So this is 1 of the challanges im facing is a build up of detritus on my barebottom tank. Is it possible to keep the bottom 99% clean? Some of the things im doing to defeat this problem is Im running 1 Vortech MP40 and 1 Korelia4 behind the rocks I will be getting another Vortech for more flow to help solve this problem. I have a 90g 48x24x18 with corner overflow. Any Opinions to help the problem are most welcome thanks
