Draining pebbletech pool during AZ summer

[V0x]

Hello all. As the subject states I'm considering having pool guy drain and refill (maybe acid wash while empty) the pool. It's summer in Phoenix 100+ degrees. Pool guy said not a big deal but someone else suggested that it's risky to drain the pool and risk pebbletech cracking.

Reason for draining is after weeks of slamming water was all good except slightly cloudy and won't go get clear. He said water is over 2 years old and calcium and TDS build up and should be drained and could explain the cloudiness. My calcium tests show 650-700.

Most common window is 24-48 hours with little to no issues at lower temperatures than 100 degrees.

It's @ 112 degrees lately. So should I infer the risk at that temp is considerable and that I should wait and deal with cloudy water for a few months?

I would drain the water while still keeping it hydrated with a sprinkler system.

Is a partial 40% drain per the app effective for this purpose or if water is 2 years old and half empty may as well completely drain and start fresh? I think the fill water here is pretty hard anyway.
