Hey guys. Well, to make a long story short I purchased a full setup used. It came with a sump filter with a filter pad and activated carbon chamber and a protein skimmer. I have been reading a book and it seems that for what I am doing, for now at least, the sump may be overkill. Being a new aquarist I am only starting small. The tank is a 75 gallon and I am looking to start with a few clown fish and a few others when i do some research. Is the sump too much?
