Overflow came without Holes.

I'd go ahead and glue the overflow on, then drill the tank at the same time you drill the overflow.

a diamond coated bit would work for acrylic?

The purple attachment on your return line.

oh thats the Loc-Line i was talking about, it looks purple because of the light and my phone camera sensor lol. you can attach a Loc-Line fitting to the bulkhead so you can aim the return flow anywhere you want, you can also add special nozzles to create turbulent flow.

Oh okay does that help with surface skimming?

i think a normal hole saw is preferred over diamond for acrylic, because acrylic is plastic, it will heat up and melt, which would gum up the diamond bit. you can still use the diamond saw but i think a bit of water and going slow would help.

your overflow box does the surface skimming, and the Loc-Line can be used to aim water at the surface for more water agitation.

Do you agree with him then, saying I shoukd glue overflow on and drill through both?

you can certainly do that, provided you really like that overflow. cant really change your mind after you put a hole through your glass lol.

nope, I'd have to get a different overflow, but I don't see any reason I'd want to change.

i really wouldnt rush through this step, as it will be something you will be looking at every time you look at your tank, if you like that box then what wesman42 said would be how i'd do it, if you arent completely sold on that box then you should shop around and see if you like any other styles before you put drill to glass

well appearance isnt something im completely ignoring, my main focus is performance.

another point to consider is how thick the box is front to back. if your tank isnt very deep (front to back) to begin with, you may want to consider a lower profile overflow as a deeper one like yours may block a bit too much area for future coral placement and growth, but if your tank is very deep then it may not be as much of a concern.

My overflow is 4 inches deep, tank is 30 inches. Not planning on putting in coral. Predator tank if anything.

ofc is all up to you and what you would like. as wesman42 said, gluing the box on then drilling would be the best way to make sure that the holes line up for the bulkheads. just make sure you let the silicone cure and use some clamps so the box doesnt move around on ya

Actually, if you're lubricating with water like you'd need to in order to cut the glass, the diamond bit will work just fine. After all, it's covered in diamond dust. It will cut through granite if you'd let it.

Okay, sounds good. Tank goes on its side for the drill correct?

Yes! Make sure you let the weight of the drill do the work and run a hose over it.

Yeah im using a gasket with water in it, a ryobi hammer drill (hammer mode off obviously)

1 3/4 inch bit

Sounds good!!

Should I just silicone the overflow into the spot I want it permanently when I drill it?
