Just an update here. My chlorine levels started bouncing around a little these last few days. I was going from between 4 and 5 ppms down to less than 1 ppm in the evenings. That's a loss of 3 to 4 ppms a day. I was not pleased with the loss (which could be from a large swimmer load or these over 100 degree temps we've been having) so I added another pound of cya. I have not tested the cya yet because it has only been in the water for less than 4 days now. It seems to be working out much better though. The last two days I am back down to about 2 ppm chlorine loss.
