My buddy bought a house and it has a pool. He had a pool inspection done on my advice prior to purchase and nothing came up that he told me. Headed over today. From the few pictures i've seen it doesn't appear to have a cell.

Update:
So went and checked it out and gave him my test kit as I have a new one showing up Monday. As I expected the CYA tested off the chart. I did it three times to confirm and it was almost completely clouded out after only a couple 'squirts'. The attached picture was the lowest test and its halfway to 100 from the bottom. The owner left a log of the pool service he had been using ($130 a month) and it was serviced last 2 weeks ago. There was a couple small chunks in the floater but the sample didn't even turn color when adding the powder for FC drop test.
FC: 0
PH: 8
CYA: High
CH: 750
The sand filter was replaced new in 2023.
The pump didn't have receipt for replacement so I'm guessing it might be original?
The heater is broken and was deemed not repairable by the pool inspector.
The pool was drained and had a bunch of work done in 2017 for re-pebble and tile and new plumbing to include autofill
We estimated at about 15,000 gallons off quick measurements but he's going to confirm depth and better measurements tonight.
The auto was running the constantly the couple hours I was there. It was 30mph winds and in direct 95 degree sun all day but mine doesn't do that in the same conditions. Told him to get a bucket and showed him how to shut off auto fill and do bucket test.
I've never had to deal with algae so don't know for sure what it is but the returns all had orangish brown below them that could be brushed off. I'd assume it's been at 0 FC for quite a while. Pictures are in next post.
So it's looking like a minimum of 50-60% water exchange to get CYA down?

Does the spa get water through autofill or does the valve have to be open to the return jets to keep the level up?

If you have a Poolmath subscription, yes, you can add another pool to your account.
However, I recommend highly that you lead him to the “pool water” so to speak rather than try to manage his pool for him- as it may not turn out well.
Install poolmath for him & show him how to use it . Set him up a tfp account & signature so we can help him directly if needed.
Send links to
Pool Care Basics
& have him get his own Test Kits Compared.
I’m not saying don’t help, but help by teaching/giving info & letting him make the moves/efforts along side you until he gets his pool legs.

If using trichlor pucks they should be discontinued once cya reaches around 50/60 and then switch to liquid chlorine for daily chlorination.
Beware of their acidic effects as well.
There are cal hypo pucks but they add calcium instead of cya which also builds up and can cause scaling. I imagine your area already has plenty of calcium in the water.
We recommend liquid chlorine or a swcg for daily chlorination & reserving pucks for vacations etc.

Exactly what my plan was as far as helping him. I learned so he can too 😀. I’m excited to see what the condition of everything is.

Have him do the test following these instructions. START at #8:

Just sent it to him along with a link here. Got him started on Pool Math app as well. Immediate action is dump a gallon of chlorine in today. He's in a bit of a bind as he's military and is gone very frequently. Not sure when we're going to be able to exchange the water. I live too far away for me to get over there frequently.

For the autofill, i found the equation for evap and with the cooler water, high air temp, and strong winds the pool lost about 627 gallons of water...
