I’ve lived in AZ for over 40 years and always had a pool and a pool service. Recently retired and was unhappy with my current service so looking forward to taking care of my own pool. Had my water tested and was advised to drain because of hardness. I drained about 90% and am refilling now. Any help would be appreciated. Thanks. I have 1 year old plaster and filter and a 3 year old pentair pump.
 
It's smart to take care of your own pool. Get your own test kit and skip the pool store testing as it is notoriously inaccurate. However, they were probably correct about needing to drain the pool because our water is high in Calcium and gets higher with water additions over the years. With new plaster you will find that your acid usage goes up for a year or more as the plaster cures. This is normal and why you need a testing kit so that you can test 2-3 times per week. When you get your testing kit then post up the following:

FC Free Chlorine (use liquid chlorine or better or install a Salt Water Chlorine Generator)
CC Combined Chlorine
CYA Stabilizer (you'll need to add some)
CH Calcium Hardness
TA Total Alkalinity
