Good evening you all, I'm trying to figure out what to do. I had a 2.5 inch hole drilled in the left Corner of my 40 gallon breeder for the glass holes over flow kit. However, the glass shop's placement is a bit low. Roughly 3.5 inches from the black trim. This means my water level is going to be extremely low. I figure I can some how implement a loc line for the return & redrill another hole on the opposite side at the right height for the desired water level. So, what are you alls recommendations? Should I try this water level or developer a loc line system and add another hole for the overflow?
