I am not sure what spa 56 is but
You want the active ingredient to be 99%
sodium dichloro-s-triazinetrione.
Then after cya is about 30ppm you would dose with bleach/liquid chlorine.
Salt is a one time addition & doesn’t leave the water unless you exchange water. It has a chemical reaction with the swg’s cell that produces free chlorine then it gets converted back to salt.
You will still need to check/dose with liquid chlorine after heavy bather loads & to be sure you are maintaining fc above min for your cya

Saltwater chlorine generators are maintainers - they aren’t designed to get you to target from zero & should be supplemented with manual chlorine additions if necessary.
Salt Water Generators are designed to produce small amounts of chlorine continuously. This is perfect for day to day use and reduces work for the homeowner.

Bromine isn’t a terrible choice & if it’s working for you great

It is my understanding that the bromine bank needs to be reactivated & this can be accomplished with multiple forms of chlorine- dichlor, bleach, or a swg.
The chlorine gets converted to bromine.
There are many who go back & forth between bromine & chlorine upon draining/refilling.
To do so requires complete water replacement. This forum is mainly chlorine based so there’s alot more available knowledge about that choice. I personally like chlorine because I am not a fan of mystery & prefer to be able to test every parameter & dose accordingly in exact amounts using
PoolMath.
With bromine you can only test for total bromine- the rest (free bromine & how much bank you have) is a guess.
Same goes for mps (non chlorine shock), & the frog’s

magic ingredients.
You mentioned a pool - it is not listed in your signature. How do you care for/sanitize it?
