My pool iz in the zone....pool calculator even said balance.
Only thing I'm concerned with now is CH is 370....and I don't want to drain anymore water.
And the stains....after brushing they are now a light brown/yellow....I may try ascorbic or citric.Was talking to a guy at the bar who use to build pools and he said try oxalic acid.
I told him about BBB and he's never heard of it...but seemed amazed.I gave him the website to check it out.
Thanks again everyone.
