Bought a pump yesterday from A.E. and right now I'm mixing up a batch of salt water to fill my sump. I am out of salt though, so once it's all dissolved, I'll check the SG in the morning to see if I need more or not. I'm going to fill my sump with the pump turned off about the level I want it and turn the pump on. Right now there's only about 5 gallons in my sump and I have 15 mixing now, I'm thinking that should be enough for now. As I stand, my overflow is primed and my ball valve is shut waiting to be opened. I'll post pics later, wife is beating at me to start cleaning the house.
