my reef tanks have 2-2" over flows and 2- 1" returns

But how much flow do you have??

I have heard that anything over 1.5 is a waste when it comes to they overflow outlined in the DIY sticky.

You are perpetuating a myth that just won't die

...bad nfored, bad...

Now go sit in time out

when it comes to tanks,or equipment, bigger IS better, ALLWAYS! to big is usually just right, no such thing as a waste.

Its hard to comment on something that you are not sure of

why is that?

It really depends on how strong is your pumps but its still better to have multiple ones than 1 big pipe coz you need to initially manually suck them or fill the whole pipe with water to start the flow

Your best bet will be to drill the tank. That's some serious flow.
I wont risk my tank
How big is the tank (out of curiosity)

I have personally drilled a tank before, its not that hard, really you could do it yourself. just make sure that the drill cuts the glass, your not trying to shove the bit through the glass. Just enough pressure to allow the teeth to grind the glass away, just make sure that you wear ear plugs and have water to pour over the glass as you cut. having someone else there is helpful.

Not really...

Those cracks that show up after a succesfull drill are due to heat stressing of the glass. Heat stressing is easily avoidable by simply keeping water flowing during the cutting process, keeping the cut groove flushed out, and not running the drill at high speed.

Any amature that can follow these three simple rules can drill like a pro (Ron Jeremy jokes withheld).
