Hello pool experts:
Here's my problem. I have an above-ground pool, 17,000 gal, that I've have for about 15 years. During this past winter (Long Island) I lost the cover, whereas all of the water and debris wound up in the pool. By the time i got around to cleaning it up, around early April, the water was black. I removed much of the leaves, got the filter going, added pounds of shock, added "black algee" stuff, and wound up with a green pool. After more pounds of shock, the water stareded to clear a little, and i noticed that the floor of the liner has stained brown, except for a section in the middle where i still had leaves. Srubbing the floor with a hard bristle brush does nothing. I don't have high-iron water, so I don't think it's iron stains. When i testedthe water last week (prior to pounds of shock) the readings were:
TDS(?): 400
CYA: not tested
Tot Chlorine: 2
Free Chlorine: 2
pH: <6.2
Tot Alkalinity: 54
Optimizer+: 0
I'm running the filter (sand) 24/7, adding a pound of shock a day, and placing 4-5 quick desolving chlorine tablets (2"?) in the skimmer a day.
As you can see, I'm shooting from the hip... any suggestions?
