Hey I'm gonna keep a positive look on this. Maybe you can use a faucet valve type thing to turn off the flow.

You CANNOT run a hole direct from the bottom of your tank to your sump. You can utilize these holes for a overflow though. You will need to run a length of pipe up to the desired water level and then have a T (for a siphon break and outlet) and then put a 90 degree elbow on the side of the T and run a hose from that to the sump. Let me see if I can find a diagram or make one.
i would personally just run pipe up and use them as overflows. i'd be a bit too nervous about your ugf type idea. but hey, that's just me.
Please do try to ignore my crappy paint diagram and try to imagine the plumbing. The goal is to basically run the hose up to where the water level should be and stick in a T and leave the end of the T facing up completely open and run the hose from the side down to your sump. In this you have essentially built an overflow but you ran your hose to a bulkhead rather than into your tank.
Without this or a similar device, you will constantly be balancing your inlet to your pump's flow and you will never achieve a true balance as your filter clogs, pump gathers debris and ages, and other variables that affect flow.
You cannot run an open system off a bulkhead below the waterline without an overflow (like I described above)!!!

I may be wrong, but I don't think that will work. Won't the water pressure from the water in the tank be enough to push water out the overflow and drain nearly all the tank?
nope, the drawing works. I have a very similar setup for mine. Water auto levels itself. However a much more simplistic way to solve his problem is a standard stand-pipe. I'm not sure why the OP would want to leave the holes in the bottom of the tank open and un utilized. However, if he goes with his original idea, he'll have a very empty tank and a very wet floor.

this will work I have seen this before a long time ago in a breeders setup using 20 30g on a same rack. he kept the t-fitting 1" below the tops of each tank and would never worry about draining the tanks down in a power failure.
well i already have a 180 with the same type of filtration on it. but it wasnt built by me. the 4 holes drain to a sump, lifted back up by a pump, had it for a year plus with no problems.
my 250 which is what im looking to set up has 3, 1 3/4 " holes and an overflow.
i see your all your points, so i have a revised plan, i just run the wet/dry thru the built in overflow, and connect all three holes together run it directly into the pipeline system and bypass any overflowing sump issues
wat is the consensus on that.
