I really want to get max flow and have decided to add a closed loop to an existing tank. The tank is 72-36-24 and has only a few SPS frags and fish in it at this time. Is it easy to drill the tank without draining it all the way? The Acrylic is 1/2 inch if that makes a difference.

I am planning for three penductors running on a Pnworld 200PS pump.

I was thinking of one 1.5 inch intake for this set up.


Thoughts and suggestion please.
