I have plans in the future to build a fish room and want a decent head pressure so that’s why I haven’t pulled a trigger on the varios. I would love an Abyzz but can’t justify the price when I can get 2 rd3 for the same price./QUOTE]
Keep in mind that most DC pumps (notably excluding Abyzz) really struggle with head pressure. If your fish room is going to be in the basement, or really on any other floor than the tank is, then you might want to factor that in to your decision-making process. I don't really see the advantage to a DC pump, but a cheap/reliable one like the VarioS, or a good AC pump like the Fluval SP, could probably be shelved for later use without blowing your budget once the fish room goes in and you need a pressure-rated pump.
