I've done a fair amount of reading over the last couple of weeks and feel like I've got a decent handle on the BBB process....but I have a few questions.
30,000 gal pool, Hayward 1.5hp pump, vinyl liner. Live in SE. Pool gets full direct sunlight from 10am until 6pm.
I believe PH is ok but based on what I've read CYA is waaay high. I've drained about 2", then refilled. Going to test CYA at the pool store in a couple of hours.
FC level is dropping 2ppm per day. Is this drop unreasonable?
It takes approx 1 gallon of Chlorox bleach to raise FC by 1ppm. Does this seem like alot?
The pool store water analysis sheet recommends "30-200ppm" for CYA. 200 ?! Thoughts?
I'm confused about CYA. 30-50 is ideal, but I've read where higher levels 80-90 will "shield" chlorine better. With my CYA as high as it is, why is the pool burning up 2ppm in chlorine every day?
Bough a pump timer and plan to cut pump time from 24/7 to hopefully 10-12 hours per day. (2 hours in the evening when I add chemical and 8-10 hours during the hottest part of the day.) Is this a reasonable expectation?
Thanks in advance!
