About a week ago I was at the local pool supplies store when some lady walked in and told of her problems to one of the sales guys.
It appears that she has an in-ground gunite pool with green algae and now cloudy water on top of that. She was there to buy more chemicals. Seems she has been fighting this problem for quite some time.
Anyway, I am no expert, but I suggested to her that it might be easier just to drain the whole pool completely and start all over with new water.
She looked at me like I was crazy .... Did I give her bad advice?
