Deciding between an overflow box with a Herbie set up or drilling 2 holes in the tank.
Ive always had an overflow box, but could I just drill 2 holes in the tank at separate heights? And the top one leave a slow trickle as an emergency?
I know I'll lose some surface skimming but it's going to be a display fuge connected to my main tank.
