Can we talk about Calcium Hardness?

Pool Math results yesterday (swg): FC 7; pH 8; TA 66; CH 250; CYA 60; CSI 0.02; Salt 3400...... Pool Math advises to add Calcium Chloride at 4lbs 10oz, by weight, or 74oz. Idk what calcium chloride is, I can look it up. Does this sound right? Pool Math Recommended says 250-650, Ideal 350-650. I've been told to ignore the "Ideal" field here before so does adding adding that amount sound right?
It does advise to add 9.4oz by weight go baking soda too for TA.
Side note- Because of hurricane Ian (Brevard County) we removed some pool water in preparation, and then added some back in what the rain didn't fill in.

No need to add any calcium. Your CH of 250 and CSI of 0.02 are within range and fine.

Leave TA as is.

No action needed - maintain FC at target level and pH in the 7's.

Wonderful, thank you!
