Where do I start with chemical correction?

[angiern2004]

FC: 0
PH: 7.2
TA: 90
CYA: 40 (how can it still be 40 from initial set up when we’ve added water a bunch of times?)

Where do I start with correcting this? We have our house on the market and the balance got away from me.

How long does the taking it down process take? I know it probably starts with scrubbing and draining, and letting the liner dry out. Is this going to be a long drawn out process if we move in a week?

I suspect you added water due to evaporation. CYA does not leave the pool water due to evaporation.

Do you need to follow the SLAM Process?

First step is to add chlorine with liquid chlorine / bleach. Use the FC/CYA Levels to get the target FC level (5ppm and never below 3ppm).

The "taking it down process"??

If you are moving in a week, I would think you have a lot more to worry about than the pool test levels and where CYA went.
Forget about testing. In your 4000 gallon pool, add 25-30 oz (a bit less than a quart) of 6% bleach each evening and forget about it.

If the pool is algae free, then you can just drain the pool and equipment and let them dry out. Probably take 2-3 days to dry out. Take a towel and dry off the insides for quicker dry time.

I wasn’t so much worried about the CYA and where it went, I just get surprised when it’s always 40. Like it makes me question if I’m doing the test right. Hahahaha.

I don’t see any algae, so I don’t need to SLAM? Or I still should? That’s my biggest question I guess.

No algae and clear water means you don't need to do the SLAM process.
TFP methods don't require regular "shocking" or SLAMing of the water. Just follow the FC/CYA Levels for daily FC levels and you are all set.
