So, just keep dumping bleach in until I can maintain Right. I thought I had it licked the other night, but by next morning it was down again.

Yep, just keep at it. The more times a day you test and add, the quicker it's going to start holding....it's letting the shock level yo-yo up and down that takes forever to clear up a problem. YOu want to shock it, then maintain that level until the chlorine holds steady overnight.

Might want to consider upping your CYA level just a little bit if you find that you're still having trouble holding a chlorine level throughout the day, once you get the pool cleaned up.
