Hi everyone, looking to see if there is any additional advice on what I am doing. I've never owned a pool and this is my first month of learning everything I can. The pool is fiberglass has an SWG, waterfall and a heater in a northern climate.

My numbers today are as follows:

FC- 5
CC-0
PH-7.7 (in between 7.6 and 7.8). have kept this between 7.4 and 7.8 (Waterfall might be contributing to the PH rise as well as TA)
TA-110 ( started at 140, been using Muriatic acid to slowly knock this down when my ph climbs to 7.8)
CYA -60 (started at 0 , increased it to 60, sometimes around 70 if the water level is down I think this is good for us up north).
CH- 240 (CH started at 40, raised it to 240. Even though its fiberglass I think it's important to have some CH. Not sure if I should increase this further)

I am still dialling in the SWG, I run it for 12 hours a day around 40-50%. On sunny days 40% isn't enough so I have kept it at 50% for now. How does everyone regulate the different days of weather needs?

Thanks,

Numbers look good.

Do not chase FC numbers. If you find your FC loss each day varies some, aim for a higher FC. Then those days the pool uses more FC, you will stay above minimum.
