Just Set Up Pool...Need some pointers

[JSMANNING0001]

Got my test in...she sold hubby moriatic acid to lower it...told me 2 cups to lower it 0.4...however I was 7.8-8.0. I did the math according to the book that come with my kit, it only needed about 1 1/2 cups ...that dropped it down to 7.2...glad I didn't put the full two cups in....is that ok? or should I know add baking soda to bring it back up.

As for the CYA, I couldn't find anything that said clarifier, condistioner or stabilizer. I did buy 1" chlorinating tabs. It says kills bacteria and controls algae... Janet told me to get Tri-chlor tabs...I guess I expected it to says that ...oops I found those tabs and got them because it says trichloro-s-triazinetrione 99.%..... Is this right? How many should I use...I forgot to get a floater so I can just put them in a sock, hang them from my ladder and still swim....do I need to keep adding bleach for a couple days or with those start adding chlorine right away? I know the CYA will take a while.... also..just to make sure, can we swim with them in there? How often should I add?

Current Readings:
FC: 0
TC: 0
CC: 0

pH: 7.2-7.3
TA : 120

Walmart is out of Borax as usual and I do have baking soda but that will raise the pH & TA won't it? Should I use it and add the tri-chlor?



Also, I have noticed today....that when I take my sample, after letting my arm dry it burns a little...could be my dry skin but it hasn't been bothering me...and it only burns on the area that was wet..nothing serious just a little noticable...could this be from no chlorine or my pH too low?
