skimmer size VS tank size

[tgoeujon]

i remember now why i didnt like my coralife ss 65, its a piece of crap!!!!! unlike my coralife 220 which has always worked great ( since i got used to it ). im wondering since i have a spare 220 would it be too heavy to hang on a standard 55 gallon tank? opinions wanted since i would love to beat the sh@# out of the 65 and then light it on fire!!!
