im going to start my 55 gallon reef soon. do you really HAVE to have a sump tank. i have talked to 100 different people and gotten 100 different opinions. some say you have to have one and others say you dont. i have seen reef tanks without them that were great. i really dont want to go through the hastle of building one it just means more money. i have a nice remora aqua c skimmer that the store tested in their reef tank and it pulled alot of gunk out. i have 2 powerheads and will run a 325gph power filter until the tank it more established then will remove it. i plan to have at least 75 lbs of liverock. isnt it true that alot of good live rock and water circulation aids the tank with good filtration? how am i doing?
