Vacation pool

[donfranko]

Hi Ben, hi Mods. Not sure I've seen this question. What is the best way to maintain a remote vaction pool? I have a pool in FL that is serviced since I'm here on and off. Took readings with an old test kit I brought down. Pool is 10,000 gal gunite, chlorinted with 3'' pucks cartridge filter, spill over spa.
Readings
FC -16
CC - 0
ALK - 100
PH - 7.2
CAL - 300 **

Calcium indicator barely turned blue, more like a clear purple with red floaters so I'm afraid it may be higher. Thanks

CYA was 100
