Is it possible to have too large of a skimmer on a tank? Just wodering as I'm looking at purchasing a SWC Xtreme 200 for my 75 gallon tank with 55 gallon sump. Only reason I'm looking at this skimmer is because if I do end up liking salt I may resetup my 220 gallon as SW. Let me know what you think or any recommendations on other skimmers!
