After reading a bit on removing dead plant material from the tank, I seem to have reached a stalemate. Most people say that it should be done but then others say that you don't have to worry about vacuuming around plants because they like a bit of detris. I may be extrapolating too much but on the farm, the easiest way to reduce fertilizer cost is to not remove the straw after a crop because it is lost nutrients. So, my question is, other than for aesthetics, does rotting plant debris cause many problems or does the nutrient cycling outweigh the problems? I've been cleaning out some of the plant material but not being meticulous about it and my plants seem to be stalled. Now to decide whether I should slacken on the cleaning or be more meticulous....
