Good morning. I'm on day 3 of my pool opening. I've been superchlorinating and adjusting ph for first two days. I have my pool really clearing up now. I have a 21,500 gal, in ground pool. I took it to 15 ppm last night as there is still algae and this morning it was 13.5 which is good. My ph is 7.7 which is ok with me i think. My stabilizer is 25 ppm.

This morning I also tested my alkalinity and calcium. My akalinity is high it's at 200. My calcium is near 25. I do have a vinyl pool but i also have a heater so i need to raise it.

My questions I have are: 1. Which should I be working on first-raising my stabilizer levels to 40-50, calcium, or alkalinity. I know by reading poolsolutions that it is suggested to only work on 1 thing at a time especially i believe alkalinity and calcium so i want to make sure. Thanks.
