Those are some pretty good looking numbers ... are you still seeing algae? I forget. How fast are you going through Chlorine? You should expect a daily drop in your FC of 2-4ppm . That is just normal and why you have to add Cl everyday.
Not sure since this is the first day since I filled it and added the chlorine last night. There is one spot by the stairs that has been there for a while that isn’t gone but everywhere else looks ok algae wise

If you see visible algae, then its best to do a SLAM and get everything back in check. You could also do an Overnight Chlorine Loss Test... then you'll know for sure if you have something biological using up your chlorine.
So last night I kind of did a SLAM and I did it for the mustard algae so I did it to 24 based off my CYA. I don’t see much algae but that one little spot is still there. I am more concerned right now about my calcium and alkalinity but I guess I can do another slam after that is fixed. I’m cleaning my filters now.

When you say you did a SLAM that implies you were able to pass the three criteria for completion. That is
1) Clear water, no algae
2) pass the OCLT
3) CC .5 or lower
So if that is true you should be good to go. If not you need to keep SLAMing.
You can add Calium Chloride or use CalHypo to bring your Ca up to the target range and I would just see if the Alkalinity comes down on its own now that you have your pool levels managed better. If not look at Lower Total Alkalinity - Trouble Free Pool

Yes, I believe I passed all 3. I checked chlorine last night and this morning and it was same. The algae is gone and CC is .5. My neighbor is a TFP user and he came and helped me today a lot. We put in calcium as well as acid and are aerating and will check in morning.

Here is the perfect post about TA by @IceShadow from Aerating effectiveness
No need to chase a "perfect" TA. TA is a self-correcting problem - if it's high, pH will rise, and you'll add acid to lower the pH, which will lower the TA.
Only need to force it lower if it's so high it's causing a problem for your CSI.

Make sure you're brushing that one suspicious spot to break it up and let the chlorine get to it. Consider CYA 40.
Such a shame about that tanning ledge...I don't know why it looks that way?
Time for calcium.....if your calcium stays too low the water can leach out calcium from the walls and weaken them.

It would be CYA/30 (round to higher 10 when between lines). For Tx, you'll likely prefer/need a CYA between 40-50, but you can determine your FC needs after a few days.

How does the water look? Is it crystal clear, no signs of algae? Just make sure you don’t need to SLAM before adding any CYA.
The water actually looks beautiful. No signs of algae.

Then you're set. 30 might be OK if your pool is mostly shaded, but in summer in Texas you might want more like 40-50. You'll know by testing daily for your FC (which you should be doing anyway) and seeing how much you lose. 2-4 ppm of FC loss per day to the sun is what should be expected - if it's more, and you're not losing any overnight, then the CYA might need to bump up a little.
Ok, what should I do? I have these spots that came back up and I tried putting the trichlor tab on the spots I could see to test it and they went away. Here is what I have. Hard to tell in pics. Should I SLAM? I just added more chlorine and acid about 2 hours ago to get levels back where they needed to be after swimming.
