CYA at 0 TA 40 what do I fix first?

[Joe_Fire]

My parents have a newly resurfaced plaster pool (well a little less than a year).
Running a Hayward SWG.

My brother has been keeping an eye on the PH, salt and Chlorine but not anything else. After hearing reports of bubbles on the pool walls
I stopped by yesterday with my TFT100 to do a thorough exam.

The Results

Aprox 15000 Gallons
FC 1
PH 8.5 (I added 18oz of acid it should be ok now)
TA 40
CH 390
CYA 0
Salt 3200
Water temp 93
Pool is in south FL and it's been very hot the last week or so.

Should I go right for the CYA and Worry about raising the TA after?
Or do the TA first?

Or both at the same time.

BTW the water looks fine,clear no algae. But the SWG is set at 100% pump running 9 hours a day

Raise the TA to about 70 and start the CYA dissolving in a sock at the same time.
