Just sold my new 125 RR, and I'm buying a 150 AGA (not RR). The dimensions are 72 x 28 Tall x 18 deep. BTW, please I don't want to hear I should buy a bigger tank! And, 150 is big to me

The tank is not drilled. My LFS is drilling it for me.

Question #1 - What size holes should I have him drill? I was thinking of the same size AGA drills on their reef ready tanks. 1.5" and 1.75" in each corner. Should I go bigger?

Question #2 - I'm planning on using a 55G as my sump/refuge, and I don't want 2000GPH running through it. Any ideas on plumbing it so I can get the most out of the tank? Ie, closed loop, 2 pumps, 1 pump, etc...

Any ideas or suggestions are greatly appreciated. Since the tank is not drilled, the options are limitless!
