So after going through a very recent debacle of purchasing a used 175 bowfront and deciding to not use it, I’m going to upgrade my 72 bowfront with either a brand new 180 or 210. I know the internal overflows on the reef ready tanks take up a lot of space but I can’t decide if I should get that or standard tank to drill myself. Also, if I drill it, I’d appreciate opinions on which overflow to buy. Thanks
