Going by that picture, does not look like 50k capacity. Calculate it with pool math to get close otherwise you'll overshoot and run into new issues.
Measure it again. 20 by 40, the shallow end is 3 and the deep is 8. The bottom has 2 slopes, but I think it's more like 36-40 gal.

TF100 just delivered:
PH=6.5
FC=2 (added 3 gallon liquid 3 hours ago)
TA=50
CYA=95 (added to much stabilizer using the strip)

Pool math says to drain 47%. Is there any other way to increase CYA?
If have to drain, I plan to drain from the main and shut off skimmers. Will that be too much pressure on main pipe?
Do i need to drain and refill 1 foot each time not to stress the vinyl liner?
I plan to raise HP after draining, believe it'll save some Borax, make sense?
And then I'll get TA right before SLAM.

It would be best to add 5 ppm FC worth of liquid chlorine each day with pump running to not let things get worse.

This will take many hours. At 6 gpm, to exchange half of your pool water will take 50 hours.

Thanks. Tested CYA again. Feel it's much lower. Tested last night in kitchen. Do I have to rest under sunlight? Black dit just now was very visible.
Also, out of LC. Can I use granule (47% cal hypo) or tablet?
