Ive been writting this a lot recently...but I feel that skimmers are the most important part of a reef tank other than the lights. I run a 75g reef, and other than bi weekly water changes, I have no filtration other than my skimmer. All my nitrogenous wastes and ammonia come out at zero. I think thats enough said.
thats interesting...
how do you take care of macro filtration? ie. filter pads
