My 40 breeder will be here next week and i'm starting to get equiptment together for it.I'm gonna put my old 30 underneath and use it for a sump so i'm guessing i should have close to 55 gallons system water.The tank is gonna be BB with minimal LR and SPS only.So what kind of skimmer would you buy?I'm trying not to spend more than $250 so keep that in mind.
