Well I am back from a wonderful 10 day vacation. I had somebody add 1.4 gal of 6% bleach Sun/Tues/Thurs. I do not use a pool cover. I turned off the heater.

I left on a Friday morning with the following numbers..

FC = 10
CC = 0
pH = 7.4 - 7.6
TA = 100
CYA = 30
Temp = 86

Returned on the following Saturday night to a perfectly clear pool...sparking actually

FC = 8
CC = 0
pH = 7.8 to 8.0
CYA = 30
Temp = 105 the temp was set at 110!!

Fortunately the person adding bleach noticed the pool was getting low and added some water.

We are still in the investigating stages...but have a few leads...
