Maybe location. We leave the pool uncovered in the winter. Even the rain
overfilling, does not cause a problem. Water goes somewhere. But we are
10' higher than the house behind us. I use a tablet floater, and acid is
added occasionally.

Same here. I spend a couple minutes a week on the pool once I got the
routine down. I will admit Henc's pool ran trouble free all summer
last year but I had the percentage up more than he liked. The year
before that I was pouring chlorine in it every week and we still had
some green days.
