I am currently getting my 75 gallon tank ready so that I can move my 50 gallon corals and fish into it. I did all the plumbing and filled it with water to test it. I have a check valve in the line for the return pump, and I marked how much overflow room I need in the sump in case of a power failure. My problem right now- I used my gate valve on my return line to set the water level and to equalize the water coming down from my main tank into my sump and what my return pump is pumping up into my display. I let it run all day, it stayed equal. I went to bed, confident that it would continue to keep the water level equal. When I got up in the morning, my display tank was about to overflow. I have searched the internet, I am having a hard time finding something that will shut my pump off when the water in the display tank gets too high. I was wondering what other people do so they don't have a flood.
