Hi, can you take a picture with a piece of white paper between the block and bright light? Those will be your true (and easiest) readings 
And yes, your PH does need to be brought up some, is the pool swimmable temp? Everyone can get in and splash the water around!

Ohhh I dumped it. Let me go do it again. One second.
It’s like 75 degrees last time I checked the temp. I don’t know what is considered swim able but my daughter is so excited I don’t think she would care. LOL

Well, usually 82+, lol, but for PH reasons, she can "hop" in, but will probably jump right back out! lol
ABC's of Pool Water Chemistry
There are several items things every pool owner should know about swimming pool water. We share details on the basics of Pool Water Chemistry.

I prefer using washing soda (it's also recommended through PoolMath ) but we don't know your TA. I don't want to suggest that overshoot PH/TA and have a PH rollercoaster 
What Are My Ideal Pool Levels?
Use our tool to find ideal chemical levels for any swimming pool. Check TFP recommended levels on pH, free chlorine, cyanuric acid, and more.

Am I supposed to check TA? I went by the seasonal pool instructions here and so far have tested CYA, pH, and chlorine. Should I do the rest? Or swim for awhile today and check it again this evening?
Go swim and enjoy the (probably frigid) POOL! heehee
You guys will be fine for now, once everything settles after swimming, re-check the PH and FC. The TA "simply" affects how fast the PH will rise or fall
So you have room to add a little Super Washing Soda (yes the stuff from the laundry aisle), but for now, you can go swimming!! Again, it's gonna be chilly I bet!
You mean more Borax? I can handle that. Haha.
Is there a recommended scale to weigh the dry chemicals? I just have this goofy kitchen scale. There’s gotta be a better way.

Yes you can use Borax, remember to keep a record how how much was added
If you use the online PoolMath, it will give you the volume or weight equivalent, most are pretty close and you don't have to be scientific accurate, as long as you don't heavily overshoot!
Higher PH is okay for vinyl, but if it doesn't start to come down, you can dose partial doses of muriatic acid as needed. Definitely try to use half what is recommended and give it time to mix in. I think borates can only be removed by draining. That is why I prefer washing soda, it might raise both PH & TA, but it can be managed without extra tests
(simply a personal preference)I didn’t get overexcited to correct the pH and it’s more like 7.6 today. My chlorine dropped to 0.5 though. I put that number in with the goal of 5 and put in that much chlorine, hoping to swim in a little while. Should I retest later tonight and slam it? I read if it gets lower than 3 to do the slam?
Maintain your FC for your CYA/40 using this FC/CYA Levels. Enjoy your pool! The SLAM Process is only needed if the pool is cloudy (or green) or not holding chlorine otherwise
