So I am about ready to test my TA and PH for my pool as the FC drops to normal levels. It is hovering around 10-11 FC at the moment. A few more hours and the sun should lower it.
Could anyone chime in on the following;
1) Due to my pool being vinyl the recommended levels mentioned 50-90+ for TA. Does that mean as long as my TA is above 50, I don't adjust it? It also mentioned that no reason to drop TA if it is 150-160 just to get into the target level.
2) CH I don't worry about as long as its below 350
3) PH I can adjust with baking soda, however; if my TA is already 150-160 it will bounce most likely to near 200. Is that okay?

I also read, that BORAX is better to raise your PH with as opposed to Baking Soda. Any advise?
