One week of TFPC...what next?

After a week of TFPC, I’m all in. My pool looks better than ever. I’m still testing FC, CC, PH, and CH (plaster pool) daily. I’m currently managing a 60 CYA but will plan to reduce that with a partial drain at some point. I’ll plan to test CYA monthly. Can I get away with testing TA weekly?

My test results over the past two days:

FC - 10/8
CC - .5/.5
PH - 7.6/7.6
TA - 90/90
CH - 260/260
CYA - 60
CSI - -.12/-.15

Since most levels are at or close to acceptable levels, I think the only thing I’ll need to do tonight is add Liquid Chlorine to make up for the 2ppm loss over the last 48 hours (range for my CYA is FC 5-9 so I do have some wiggle room, right?) Do I need to perform an overnight loss test or is it possible that the loss is normal loss due to sun exposure? My pool does get full sun all day. It is crystal clear and I have full pressure on my filter since I cleaned it and replaced the cartridges a week ago.

Am I on the right track?

Thanks!

Normal FC loss is 2-4 per day. You're there, so I don't think there's any problem brewing.

You can skip the TA test unless the pH needs adjusting. Then you'll need to know it to calculate the dose.

60 CYA is okay if you get solid sun. It's only going to be a problem if you get algae. And it will go down slowly with splashout and normal breakdown

I'd say you're on the right track. .

Thank you, Richard. Breathing easier about the 60 CYA. I appreciate your feedback and am happy to know I’m headed in the right direction. I’m actually enjoying the testing and feel a lot more confident about my ability to take care of my own pool. If I can save some money in the process, bonus!
