this is a 75 gallon "reef ready tank" (hardly) in the overflow there are 2 holes. 1 for the return that is 3/4 inch and one for the filtration that is 1 inch. Before going further let me say that I wont be drilling this tank. It isn't mine and I don't want to replace it should it break.
So what ive done is plumbed the return over the back, and i have 2 full siphon drains in the overflow. 1 that is 3/4 to use all the time and 1 that is 1 inch for emergencies. They are going to be made slightly shorter than the pic. Anything I can do better?
