Overflow plumbing poll

[jsweir]

Trying to figure out how to plumb my 240 gallon overflow it has a center overflow with 4 holes - 1" x 1 1/2" x 1 1/2" x 1". My initial thought is do a herbie style with one 1 1/2" full siphon and the other 1 1/2" as emergency. I would use one 1" for return and cap the other.

Let me know what you think

With a tank that size, I would want the redundancy of a bean animal.

Seems obvious to me ..... One of the 1” for the main siphon, the other for the return. One of the 1 1/2” for the bean secondary, the other for the emergency.

Appreciate the advice, think I will go with that. Never had a tank with 4 holes in one overflow
