Flamenco, it sounds like I'm in a similar situation. I have designed but not yet built my drip system. I have a central sump running about 500gal of tanks in my basement. Being that the sump is on the floor in the basement, I don't really have anywhere to drain the water to. My plan is to set up the dripper so it drips 24/7, maybe 30 gallons per day. I'm on well water so I don't need to worry about dechlorinator, which is nice. I'm going to put a flaot valve in my sump with high (on) and low (off) level switches, so when the water in the sump rises to say 10", the pump will kick on and drain the sump to maybe 4".
Fishdance, how would you drain from one of the main tanks? Using overflows into the sump, the level increase will show up in the sump rather than the main tank. I guess you could adjust the height of the two overflows in the main tank so maybe 10% of water goes down the drainage overflow and the rest goes down the sump return overflow, but that sounds like it would be really finicky to adjust.
