Im sure some of you have seen me around the forum here and there but mostly in the DIY threads. Thats because I consider myself kinda handy and would love to one day build a crazy MOnster tank of some sort or other currently i have only a 30 gallon and a twenty gallon breeder . anyway and a ten gallon in my gf's sons room . anyway I want to know if there is any way to create an overflow for my tank without drilling into the side of the tank.
