I would like to plumb in a grow out tank into my 30g in wall w/ 25g sump. The grow out system will me three to four feet below the sump. The tank I have has two bulkheads in the back top left and right corners. What is the best plumbing design to be careful of running a pump dry and overflowing. I was thinking about drilling a hole in the sump, with half the hole under the water line which is kept by a auto top off and have that gravity feed into the grow out tank. Then I was going to use a 90 degree elbow down about half way to the bottom of the tank and run a pump in line back up to the sump with a check valve so it does not siphon back into the grow out system. Does this sound good? So when I go to feed the tank, I just leave the pump of the grow out system on and then the water will just circulate between the sump and grow out tank. I would love some better or different ideas of how it can be done so I dont have water all over the floor if the power goes out.... Thanks Dave
