Hi
I can not seem to maintain an adequate chlorine level in my salt water pool. I have a brand new in-ground liner pool with a salt water chlorine generator. The details are as follows:

In Ground
30'000 Gallons
Pool Pilot Digital Nano
Ozonator
82 degrees Fahrenheit
Free Chlorine 0
Total Chlorine 0
Combined Chlorine 0
Alkalinity 57 (I know this is low and i am adjusting it today)
Ph 7.3
CYA 79 (I am keeping this high per the manufacturers recommendation)
Calcium Hardness 382
Salt 3200

Everything should be ok, but I cant get the chlorine level up. I have shocked the pool several times and then its OK for a few days before it goes down again. The pool is in full sunlight for about 6-8 hours per day.

Is there something wrong with my salt water system?

Thanks you for any help / input.
