Do you guys think a tunze nano 9002 would be big enough for a 46 gallon bowfront tank containing soft corals and lps (no sps). I like the look and size of these skimmers and have heard they are extremely quite, and have no chance of overflowing into the floor like a hang on back. If they did overflow it would go back into the tank. I am paranoid about having an overflow into my floor? Also does anyone know how hard they are to get skimming good? Are they worth the extra money, or would I be better with an octopus (which has been recomended to me) or an aqua C? I want something fairly quiet, easy to adjust and with little chance of having water in my floor? Please input.
