chlorine questions

[str8deal]

Well, it's been over a month since I started this post and after following Carl's advice I had the chlorine and ph levels looking really good. In fact, my husband was amazed at what a better job the cleaning system was doing as we always had one spot in the pool where dirt had a tendency to accumulate. We thought it was the head but once the pool numbers were adjusted it cleared up. PROBLEM: we had some pretty heavy winds for about a week and I'm not sure if that has anything to do with it or not, but since then I can't get the numbers back. The chlorine level keeps reading under 3 (we had it up around 11-15 because of our high cya number) no matter how much bleach I put in and the ph level is staying just above 8 even though I keep putting acid in. Would a shock treatment help and if so what should I use? Or should I just put 4-5 gallons of bleach in? Please help, I am becoming frustrated.

How much bleach are you adding at a time? Is your pH still at 170? Have you added anything else other than bleach and acid. You don't need a special product called shock treatment. Bleach is all you need.
