Thanks! We're so lucky that we could get it going again.
After fish and frogs have survived a year, I'm also going to declare my automatic water level valve setup a success. We've been able to set the float so that it compensates for our slow leak but doesn't immediately drain the rain barrel that feeds it. Here's a picture of the copper float and the frog that's enjoying this beautiful day with me. I was worried about the copper harming fish and frogs, but my water test kit and happy creatures tell me we're doing just fine.
