yes 48x18x24 is a standard size but im looking at them because all the package tanks that i have seen in the colour i want are ####e and i want decent quality tank. and to be honest the filter lights etc that came with it would of been changed anyway so may as well just get a good tank and get my own equipment . have been speaking to a fella from these forums in harlow who had his tanks built in his home by nd and he had nothing but praise for them . plus i can have the rear panel black if i want and have either black or clear silicone and choose my cabinet style . so instead of paying 425 for a crap package tank and then well over 100 on new equipment i may as well just go for the good quality tank and get the equipment i would of got anyway. after all its going in my living room so i want it spot on
