I just tested my pool again this morning. I plugged in my rests from my Taylor 2006C kit to pool math and I am a little confused about a couple of readings from it. Herr are my numbers.
FC 10 ml= 10 DROPS X .5= 5 ppm
CC 10ml = 2 drops x .5= 1 ppm
PH = 7.4 ppm
CYA= 90PPM
TA 25 ml= 11drops x 10= 110ppm
Cal Hard 25 ml= 30 drops x 10 = 130 ppm.
When I plugged them into pool math I got the following recommendations
For TA it suggested to get it down from 110 to 70 by reducing the PH to 7.0 to 7.2 with Acid then aerate to increase PH. What acid should I use and what does mean by aerate?
But on my PH test is says to increase it from 7.4 to 7.6 by adding 10 Oz. Of washing soda. To get it to 7.6. So I am totally confuses on what I need to do for my PH.
My final question is on the calcium Hardness. I just tested it an I haven't been testing it like the others but now it's at 130 ppm and the pool math says it should be at a target of 450. And to raise it I should add 30 lbs of calcium chloride. How do I add that and is that something I need to check daily?
Would I have to wait to bring all of these up to the recommended levels before swimming?

I added screenshot of my pool math test. Any help provided would be appreciated..

300 ppm - not 130 ppm.

Use the FC/CYA Levels chart and keep your FC near the top of the target range.
Remember, pH test is invalid when FC > 10 - so let FC drop to 10 or less before tesring pH.

Use muriatic acid to adjust pH lower when needed.
Your TA will slowly come down with each muriatic acid addition.

CYA= 90PPM
When your CYA is 90 or above, do the diluted test, #8 in this article.


Your pH will rise naturally, no need to raise it with chemicals. When it rises to 8.0, then reduce to 7.6 or so with muriatic acid. This will also reduce TA. If and when your TA gets to 60-80, your pH should be fairly stable around 7.8-8. If you have high TA Fill water, you may not get your TA to 60-80. Test your Fill water for TA. What is it?

A CH of 300 is just fine, no need to raise it. What is your fill water CH?
