7.8 is the top of the recommended range. Do you have a rise in PH? If so, you should add MA to lower your PH.

Still having issues with PH keep raising, I added some M-Acid the other day and it went to 7.5 but now back up to 8.2.

Are you running any water features? Waterfall, bubblers, etc will raise PH. You can continue to lower your TA to 60 or even 50 to see if your PH will stabilize. Pool School - Lower Total Alkalinity
If TA gets to 50 and PH still rises then you might want to add borates, Borates - Why and How

I do have 2 small water falls - No Spa, and the system runs with water feature with no way of stopping it independantly. I may see how the pool does over the next few days and then look at borates. Thanks for the suggestions.
I would be surprised if there weren't a valve to shut off those waterfalls. Post a pic of your equipment pad and we'll see.
I believe it's the valve on the top left. Should I turn it off completely or should I run in on occasions?

Yes, that is likely it. I would only run it when you are out there and want to enjoy it. There isn't really any reason to run it since there aren't any areas that could hold water or grow algae. We leave our waterfall off almost all the time. Except today during the pool party!
That should help your PH and TA situation a lot.
Nice pool!

Thanks Pooldv - I'm going to give that a try - kids are playing away today but will switch off tonight and hopefully PH will stablize.
