It's calcium chloride and it's what you should use if you need to raise the calcium a lot. Cal hypo will not raise your calcium that quickly.
...will that stuff work too? I'd like to get rid of it if I can...I can use the calcium hypo next time (i didn't even know they made that). Should I shoot for 250-300ppm do you think?
Then I can do TA tomorrow evening.
When you add the baking soda add a small amount at a time dissolved in water and broadast it in the pool. If you see any local cloudiness develop you are adding too much at once and you need to add less at a time.
Then I can adjust the pH as needed (probably add some acid) Thursday morning. Then shock with bleach before I leave Thursday. Hopefully, my water will still look pretty when I get home Sunday night. Thanks!
Sounds like a plan. It's generally a good idea to wait about 24 hours after raising TA so the pool can stabilizer. There is a bit of chemistry going on in the water when you raise TA with baking soda but you should be ok.
