I opened my AG this weekend. It was crystal clear and beautiful. I've had it covered all winter, but still ran it every two weeks for about 4 hours and put some liquid chlorine in it each run. Opened it up, the PH is perfect, the Chlorine needs to come up a bit, but its perfectly clear. Ran the vacuum just to test it, and ran the pump for about 6 hours.
The only issue I have, someone (I guess myself since I'm the one that cleans the pool) left a hair pin in the pool, and no I'm not the one that wears them. It rusted a bit, I tried to scrub it up, but the stain is there to stay. My concern is with the vinyl liner, will the rust eat throug it? Its on the very bottom, so it would be a pain to put a patch on.
