Have an inground pool vinyl liner first year owning it. 19500 gallons water temp is 84 I tried attaching recent test results. Last week and went to local pool store with similar numbers and they told me to add three bags of green out shock treatment and superchlorinator. Also going to attach pics of equipment set up. Pool pilot is running at 82% purifier. Any advice would be greatly appreciated
New to owning pool numbers are concerning me please help

A couple questions that will drive this conversation:
- How does the water look? Crystal clear or cloudy?
- Are those your own test results from a TF-100 or Taylor K_2006C test kit, or are they from the pool store?

Pool water looks clear test kit is Taylor k-2006 my results not pool store. Walls feel a little slimy but nothing else going on, last week seemed like a little yellow algae was growing, went to local pool store and they recommended the green out shock treatment and superchlorinator which I added three bags of. Yellow color on walls has gone away but the numbers are what they are. Curious if issue is cya being so low and if I need to ramp up swg
Okay, based on what you told us I would recommend a SLAM Process. You already saw algae to some degree recently and the walls feel slimy. The pool store products did not eliminate the algae that's for sure, only disguised it for a while. So from here I would:
1. Increase your CYA to "30" only for now. Use the PoolMath APP to help you with the proper amount. Since you suspect you have some CYA in there, only increase the CYA by 20 ppm and check it again tomorrow to see if it's 30 or 40.
2. Lower the pH to 7.2 and then increase the FC to 12 and keep it there with liquid chlorine or regular bleach. You can turn off the SWG during the SLAM Process since it's not really designed to maintain such a high output.
3. Follow all the notes on the SLAM Process page and stick to just liquid chlorine/bleach from now on. That's your best tool against algae.
Let us know if you have any questions. Good luck!

Will we be able to go in the pool during this process? So if I get this I should raise the cya first, could take a day or so. Then use liquid chlorine and shut off swg?

You can swim as long as your are at or below SLAM level and can see the bottom of the entire pool.
Can and should I add all the chemicals at one time, the cya, the dry acid to lower ph and the liquid chlorine?
Right away you can have the sock soaking with the stabilizer. After about 20 minutes, squeeze the soft a lot to get the milky stabilizer out. At the same time the sock is soaking, lower the pH first with muriatic acid. Test the pH about 20 minutes later to see if the pH readied the 7.2 range. Once the pH has been lowered, increase the FC to your SLAM FC level (i.e. 12) ad do your best to keep it there.
I added the dry acid to lower ph, socks are soaking. I got 4 gallons of super shock. What would this fall under in the pool math app as additive and amount to raise fc

I see that but that option does not come up on the pool math app these are the options I see

"Type of sanitizer" you may have to just say bleach, then 12.5%. Even though it's a powdered form, I don't know if there is a non-stabilized powder 12.5% selection. I'm not on my APP at the moment.
Ugh.
I don't know why when I saw that pic above I thought it was a bucket. So yes, 12.5% liquid chlorine/bleach is the ticket.
Ok so ph is down to 7.2, socks are soaking and bleach has been added. Any further advice/actions need to be taken?
You are ready to slam. Since you have algae, you'll probably need more than 4 gallons for your size pool. Just don't run out in the middle of the slam.
