The tank is 190 US Gallons and measures 60" long x 24" wide x 30" tall. The wet/dry sump is 50 gallons. This is my fist really large tank and my first wet/dry sump setup. I did enough research (and got lucky enough, lol) to get it plumbed properly and everything works as it should.
I have two drain lines and one return line. Each line has a ball valve so they can be shut off. With the valves open and the pump shut off, the water that drains from the tank only adds a couple of inches of water to the sump, so there's some room to play with. So, how full should my sump be? See the picture below to see how it is right now. Should there be more water or less?
