Need to pick everyone's brains.
I just picked up a 150 gallon 2x2x5 tank.
I am presently going to use it as a growout tank for a pleco breeding project.
I figured reefers would most likely have broached this subject and would be the most knowledgeable.
If it makes any difference the front glass is starphire.
It is eurobraced with 3" x 1/2" glas siliconed on top of tank walls coming out flush with the outer edge of the glass.

I want to use a monster eheim 2080 filter that I already have.
The issue I have is that the pickups and returns only bride a 2 1/2" rim whereas mine is 3"

Do you think I am asking for trouble if I were to drill 3 one inch holes thru the eurobracing on the short side?
