OK, with your numbers you cannot use Tri-chlor pucks anymore without getting into high CYA low pH problems. (if you are using them). If not, not to worry.

Your CC is 1. This concerns me. I'm not an SWG expert but I do know that with a CYA of 50 (close enough) you should be keeping your regular FC closer to 5 or 6 ppm--and because your CC is 1, FC of 3 is clearly too low--the CYA fully dissolving in (if it hasn't already) will make the problem WORSE, not better.

Actually, I'd like to see you shock the pool up to 15ppm to clear out that CC. Use ordinary laundry bleach to do that.

pH of 7.2 is nothing to worry about. It's a tad low but I would NOT adjust it since it's still well within the safe range (above 6.9). SWGs are notorious for pushing pH up for you, so in a while you may need to add acid. Aerating the water is the ONLY way you should raise your pH at this time. But the pH is still perfectly safe for swimming.

Alkalinity is PERFECT! Don't mess with it.

I'm guessing you have a concrete pool. If it's vinyl, don't worrry about or add calcium--you don't need it and it's only a problem when you have too much (500ppm). However, if it's concrete/tile/plaster/gunite you need to raise it to the 200-400ppm range.

For your sake, I hope CYA is where it's going to be. If it goes higher, you'll have to set your chlorine levels higher.

Not sure about the salt--I suspect as you backwash and refill it will get less salty tasting.
