I have 2 overflows that are built in on my 200 gallon acrylic tank.
I had standard bulkheads but one cracked so i bought some heavy duty ones.
The heavy duty ones are about 1/4" wider in diameter and will not fit into the holes on the tank.
What is my best course of action to make these holes larger?
the acrylic is 1/2" thick.
tank is currently all drained out.
