Was wanting to make my tank reef ready and was only going to drill it if I could find an overlow kit that I can silicone to the back. Im not a big fan of the hang on back overflows, but will go that route if I HAVE too. I have looked around on salt water aquarium sites and cannot find nothing. Looks like they are going to be hard to locate, even harder finding one 31-1/2" tall :? Any help would be appreciated.
