I have a heavily planted 30 gallon tank and its hard to get the vacuum in all the densely planted areas without messing up the plants. Debris is coming off plants and needs to be cleaned somehow. I was wondering if getting a small powerhead to get some flow will help get the debris moving around so the filter can suck it up will help or if anyone has any ideas? I tried shrimp but something is eating them. I have a few mystery snails and bristle nose pleccos that don't seem to be doing the trick. All suggestions are welcome!
