JO - thanks for the heads up. However, my pool was started up by my builder on June 8 and they have been maintaining it until yesterday when they "turned it over to me." The pool guy had consistent trouble running a high ph but supposedly had it balanced by yesterday.

In taking care of some punch list items before "pool school," he utilized 2 jugs of muriatic acid to clean some stains from the plaster in various areas. Then he left and those were the numbers I was left to deal with.
