I'm helping out a friend who just bought a house with a 10,000 gallon AGP. Needless to say it's bright green. I helped him run some initial tests using my kit and started him off on SLAMing it (still using my kit). We are still in the middle of this with readings like:
CC:1.5 (down from 2 when we started)
forget the TA and CH values (log sheet is at his place) but they were reasonable.
The short of it though is that he and his wife don't have the time and money to continue SLAMing it back to sparkling (currently trying to sell old house and floating two mortgages, 2 young kids, etc). They can't even move into the new place for another month. So they've asked me whether it's possible to just close it as is (still green) and deal with it in the spring when they can dedicate time and money to it.
Are there any long-term concerns with closing it while green that I should pass on to them?
