Please help me choose a new skimmer. I have been putting this off for to long and a little coralife superskimmer 220 is no where near what I need for my system setup and bioload. I have been doning alot of research over the past three months on this. I would rather not have to spend over a 1000, but aiming for the 500-600 range. I know that both these skimmer require a good strong higher watt pump, but also for that price range they the best and most trouble free skimmers without having to mod them in anyway. I aiming trying to decided bettween the my reefcreations MR or MRC -2 or 3 or ETSS 600 ot 800. My tank is a 220 with 75 gallon sump/refug.
