I am starting the season, and I found out that my pH is 8.2 while CYA is 25. What would be the recommendation to balance the water in this case?
High pH, low CYA

You want to lower the pH with muriatic acid to around 7.6-7.8. That should help to control scale. Then you want to increase the CYA to about 40 this time of year for a non-salt pool in your area. Use the sock-soaking method to soak and dissolve the stabilizer. Be sure to keep the FC balanced to the new CYA level as noted on the FC/CYA Levels to prevent algae.
Just curious, could you add the CYA and then adjust PH after since the CYA will bring the PH down a little?

The effects on pH from the CYA will be negligible. Nothing like muriatic acid. I would just consider them separate.
There is an app for your smart phone called PoolMath by TFP. Download the app, it’s free, and it will help you figure out how much of each chemical to add.
