+1. This has been a real fight for sure and hats off for seeing this through! GREAT JOB! And thanks so much for your great reports back; I know this has taken a real effort; alot of time; and very frustrating, but everyone has learned and is still learning so much from your experience.
I don't know, with how little I understood about SLAMing before this thread, if I would have hung it there like she did when if I were getting 2.5-FC after all that bleach. I might have thought..."these people are crazy...the bleach ain't working...I'm going back to the pool store and see what they know". The OP didn't do that though. She hung in there and is now going to whoop it. If she had done what I might have done, it likely would have all been all a waste of time, effort and money, and the pool would likely still be in the same shape.
For a while it was like watching a boxing match; the pool was ahead on all judges cards through the first three rounds, and she had gone through two standing eight counts. I was afraid her husband, as her coach/manager or trainer, was going to throw in the towel and have her committed for insanity and it'd all be over. But then she threw a right cross in the fourth round and everything changed; she's now got the upper hand. The coach is probably thinking she can win now. Hopefully, she'll get a knock out and won't have to go the distance.
