We also has a big dust storm while I was away but I came home to a crystal clear pool. I always store my liquid chlorine or bleach inside where it's cooler (78 degrees). I buy 4 gallons at a time and they last me about 2 weeks.

Oh and I'm also having to add muriatic acid ever so often but my fill water has very high pH, so you have to figure that into everything as well.

Where are you buying your liquid chlorine?

Wow, you burned through that chlorine pretty fast. I seem to go through about 3.5 ppm of chlorine a day on a sunny summer day, which seems pretty high to me. I'm wondering if raising my cya to 60 would slow the FC usage without messing up the chemical balance of the pool. By the way, what is your TA?

I've been getting my chlorine mostly at Albertson's. I'll have to look to see if they are printing a manufacture date on the box. I didn't realize that it loses effectiveness in heat.
