A renter with a pool!

Aim for a pH of 7.6 when you use Pool Math to calculate the amount of muriatic acid to add. You will need to enter your TA as well.
When it comes time for the salt, add 75% of what you calculate. Let it dissolve and wait 24 hours. Test again and add more if necessary.

I don't see how to add two things into Pool Math at the same time. Is that what you're saying @Teald024 ?
I'll go with the 75% - thanks for the suggestion.

Let's say I need to add 32 oz of 31.45% MA. Do I "eyeball it" or measure with a measuring cup?
I eyeball to the nearest quarter gallon which is what yours is calling for. I mean how close do you think you actually have your volume to being correct 
Fair enough, @jblizzle! Just was wondering what forum members did!
Any ideas out there on why my pH tests (meter and the one that comes with the TF-100) are so far off from the pool store?

My default answer to that is that we don't trust pool store testing. Also the pH is the parameter that will drift the most after taking the sample, so it will change by the time you get to the store.

I use cheap plastic measuring cups. But I have to be very careful not to spill or get any on my clothes or to leave the bottle open and to work fast because of the fumes.
Best guess is probably a better way. ;D

PoolMath needs to know pool volume, starting pH, desired pH and TA to calculate how much acid you need. If you are using the online version, TA is lower down.
The fumes aren’t friendly on the 32% MA

Yeah, the fumes are pretty bad. I've switched to the "green" version which is 1/2 strength and costs more for the same amount of liquid. (I'm sure it's not green in the sense of any more environmentally friendly as you have to use twice as much so twice as much plastic, energy to transport, etc. I try to be green in the environmental sense, but can't do it here.) Other's here says it isn't worth the extra cost, but it is to me. Just want you to know your options.

I had to step away from it a couple of times and clear my lungs when I used muriatic acid the other day pouring it into a measuring cup.
Just be careful.
Hold your breath, that’s what I do. That stuff is nasty and make sure you are not down wind of it.

I’m rather type A and like knowing I added the right amount. >.>
Sorry you haven't gotten a response. I'n not sure what it is but have a couple of ideas. Is it hard, soft, sticky? Will it wash off? How big are the spots? How about another pic that is zoomed out a bit.
Could it be bird droppings?

I can’t really “feel” it so not sure! I tried to scrub it off with my pool brush with zero success! I’ll try to post more pictures when I get home.
Its hard to say. It looks kind of like something granular was spilled on the concrete. If you can't brush it away and it doesn't feel any different then something probably got spilled on the concrete, but I have no idea what. Could have been some chemical that was put in the pool and blew around before it hit water.
