both of those skimmers are total crap, dont waste the money!!!
the 26' "wadu" body and "sedra 5000" pump combo i showed you on customaquatic will kick both of those skimmers butts up one side and down the other.
berlin skimmers just make me laugh, because they are a total joke. dont get suckered!!
at least the tubofloater is half way decent if you upgrade the pump, but why bother when you can spend the same money for a real skimmer.
also check out asmskimmer.com $243.00 for an A.S.M. G-3, it would eat those 2 skimmers for breakfast.
