Closing pool water chemistry help

[chi-chi]

Hello everyone I hope this is posted to the correct forum, but I need help balancing my levels before I close my pool in a few days...

I am somewhat color blind so it's a little difficult and I could use some help.. using the Taylor K-2006C here are my results and pictures in case my colorblindness messed up the readings but here's what I got..

PH- 7.1
TA- 80ppm
CH- 150?
CYA- less than 30ppm (I assume I need to raise this with the powder and get it to 30?)

Pictures of the tests attached . Thanks in advance!

Chi-Chi, even though the digital says about 7.9, your color drop test pH looks to be about 7.3 - 7.4, so I'd just leave that alone. The digital meters can be finicky if not perfectly calibrated. For the TA, that's a good Barbie Red/Pink, so a TA of 80 is fine. CH is a baby blue which is good, but for your vinyl pool CH doesn't matter (unless it's really high), so you can just ignore that one. I would ensure you have at least a CYA of 30. Even if you go slightly higher than 30 it's fine. The stabilizer helps not only from the sun's UV, but also to protect the liner from the chlorine.

Good job!

Wow thanks so much because I've been so afraid to close and winterize my pool! Being colorblind makes some of the color matching difficult for me but I try my best. I will definitely be adding chlorine stabilizer to bring up the CYA and then comes the next challenge of plugging and blowing out lines! Thanks @Texas Splash
