I have a 300g custom tank. two 1.5 inch holes drilled in the top of the left smaller panel of the tank to overflow into a custom sump on the side of the tank. I drilled two 1 inch holes on the bottom to filter into a 40 breeder, then back into my tank from the other side.
question is will the custom sump fill faster than the water can get out? again, two 1.5 inch holes gravity draining into it, two 1 inch holes coming out.
will I need to drill a third hole to have similar flow out of the sump and into the 40 breeder?
thank you!
