*edit*
Ok really sorry about the poor info on the last post lol, here is the deal i havent bought my tank and these are the ones im interested in, and yes, a few of them dont have a drilled overflow. And it will be a reef tank with softies, and a few reef safe fish here and there

, im also looking into fragging and propogation once the tank is established and i learn a little more about fragging and propogation, also i already have a catilina 1000
canister filter, and a seaclone 100 skimmer, which im looking to replace for a nicer one, i also have the lighting covered, (metal halides) what do you guys recommend for the filtiration on these particular tanks i picked out which correspond with my budget, (looking to spend 800-900 on tank and stand, and 500 on the filtiration, (already have good lighting)
