21k gal, inground, pool heater, vinyl liner that is now brand new. Had crystal clear well water trucked in to fill the pool. I'm not a newbie to TFP or maintaining levels on my own, but I haven't had to do a big swing on so many variables before. I know what steps to take, I just don't know if I should do one in any specific order.
Here are my readings from my TF-100 test kit. I didn't test chlorine or CYA as I didn't add any and they aren't naturally found in deep wells
pH - 6.7
TA - 40
CH - 40
FC/CC - 0
CYA - 0
Should I really just bring the FC up to 3, toss in 2 boxes of borax, 19lbs of baking soda, 51lbs of calcium chloride, and 7lbs of stabilizer all at once? (pool math output) I was planning on having people over on Saturday and I will be starting whatever process it is I am going to do on Friday. What do you suggest? I'm concerned about the CH/TA/pH levels and my pool heater as I want to run that as well.
