Increased Ph 8.0? Should I decrease and if so, how?

What is TA? Where do I buy MA at?

[FormerBromineUser]

TA stands for total alkalinity and you should have a TA test in your kit, assuming you have the Taylor 2006 which is our recommended testkit.

You can buy MA, muriatic acid, in the paint section of any hardware or big box home store. Here is a link on how to handle MA just in case you are not familiar with it: http://www.poolforum.com/pf2/showthread.php/13111

My TA 140. Is 3c still good?

[FormerBromineUser]

Yup. Retest it after a couple of hours and see where you are.

You have to be careful which bottle of MA you get, there is a diluted product at my local Lowe's that they usually put right out front at eye level, and then the stronger stuff they hide down low and behind everything. They aren't labeled very well either, so its hard to know what strength you are getting.

I did about 1/2 the quart of MA then test after 2 hours. Ph still 7.8-8.0. I added the rest of MA and retested 1 hour later. Ph bout 7.5😄 Cl 6 after 1/2 gallon of bleach. Thank you so much!!

You are welcome!!!
Have you ever tried going a little higher with your FC goal? With a CYA of 80, I would consider that.

You're bordering on the low end of the range with 6. Trying to stay at 8-9 might be better. But if your pool does well with a lower goal, that's fine!
