Hi folks,
Great that so many are being helpful with suggestions. Also nice that they are all the same suggestion (shocking w chlorine), which keeps a novice like me from having to wonder about which suggestion is the right one.
However, if all these really elementary suggestions to shock are correct, why can't my local pool company in business almost 50 years offer me the same solution? That's what worries me. I don't know how smart they are, but I figure they've faced by now nearly every conceivable problem in pool management and maintenance, yet they had no answer for me on this issue.
Of course, I shouldn't ask you folks why they don't know this, I guess I'll have to ask them.
Thanks again for all the great generous suggestions.
Best,
-- Josh
