I am now north of Dallas in Frisco.
However, I grew up in Tomball. Very familiar with the area... This was back when there was only 1 high school... now I think they have 2.....
We lived off 2920 near Rose Hill.. Right around D&D feed and supply.

I am from Houston originally, I have lived in Tomball on and off since 2010, I bought a house off 249 and Highway 99 this past February. Highway 99 is new that goes around Houston.
Another consideration on chlorine tabs, I used them for years and our eyes burned badly in the water due to a very low PH level. The tabs are highly acidic and makes maintaining a balance PH level pretty difficult. I switched to liquid chlorine a few years ago after being forced to drain the pool and am now on salt and the water has been much more comfortable.
I buy liquid chlorine by the cases for the season. I store mine in the basement which is cool and dark. Whatever is left over in the fall I use for my white laundry. LOL I just have to remember its 10% and not 6%. I usually buy upwards of 30 cases in early May.
I wish I had a basement!! In this part of the country it's not common at all.
Todays water test:
FC = 7 adding 8.2 oz of liquid chlorine to keep my target at 8
PH = 7.4
TA = 100
CH = 80
CYA = 50

Numbers look good!
How are you liking that test kit?
@ddmckmle, I used to live a couple miles south of you in and then in Cypress back in 2009-2011.

I bought the premium subscription for PoolMath on my phone but it will not let me add more than 1 day on my computer.
My test results for to day:
FC = 8
CC = 0
PH = 7.4
TA = 100
CH = 70
CYA = 50
CSI = -0.72
Why CSI so low?

Check out this article on the CSI - Calcium Saturation Index (CSI) - Trouble Free Pool
In a nutshell, low CSI can cause calcium to pull out of plaster. High CSI can cause scale to form.
If your pool is vinyl there isn't any calcium to pull out of the walls of the pool, so you're fine.

CSI is low because of your pH and very low CH of 70ppm. BUT, you have a vinyl pool so a negative CSI is perfectly acceptable. I wouldn’t let CH get any lower since it could lead to foaming if the water. No need to have more than 100ppm CH in your pool. Don’t add CH unless the CH continues to drop.
Are you filling the pool with rain water or through a softener?

Yeah, lots of rain can drop CH. Keep an eye on the CH weekly and adjust if you need to. Note my comments from above.
