I am not a mod, but I know in order to give you answers you need to post a set of readings from a good test kit, like the Taylor K2006, and you need to post what you typically put in your pool, how much, what was in the "bottle", etc. If you don't have a K2006, order one now, and while you wait get yourself a cheap OTO test kit at Walmart, test your pool and post the numbers. You will need to post you CL (chlorine), CC (combined chlorine), pH, CYA (stabilizer), and alkalinity.

On an aside, you might not get much of a response right now as this forum is on the way out and traffic has really dropped off.
