Thank you!

I have a Taylor 2006-C kit. Pool is 20,000 gallons, ~7 years old, gunite, sat for 2 years filled, not maintained (house was foreclosed) before we purchased 4 years ago. Our second pool. Needs a resurface soon, lot of pitting in the plaster. Stay rite system 3 filter, two 2HP pumps, one for pool, one for jacuzzi.

Was using 3" tablets, but the CYA went through the roof. Reading some info on the forum, now switched to liquid bleach.

My current #s:
PH 7.2
FC 2.0
CC 1.4
CYA 75!
Alkalinity 130
Calcium 250

Questions?
1. How overall are the #s? I've read in the kit, the preferred, but curious as to what you all may have to say.
2. How many x/week to check the chemicals? Is it preferred to always check ALL the above?

Thanks much in advance for any advice!
