My pool is an AG 24 round, 15K gallons. It get the sun most of the day but the solar cover is on when not in use. The water temp has been around 78-80 the last few days. I shocked it on sunday to 14ppm. Tuesday it was 4ppm, I added 3/4 gallon bleach last night and this after noon it was back down to 3ppm.
I seem to be going through several gallons of bleach a week just trying to keep it between 5-6ppm.

Since I have a Vinyl liner I wont shock above 15ppm so im not sure if that has something to do with it. My next step is to drain some water any try working with my cya 20-30.
Thanks'
John
