Need advice on the next steps to balance my pool's chemistry

[aussieta]

just going to add a little as you are mostly on track
if you place the cya in the skimmer basket you must keep pump running and an additional 24 hours after it has dissolved as it will now be caught in your filter and is highly acidic, if in front of return , not touching sides, pump can be turned off
dont forget to adjust your fc to allow for the increase in cya, you are borderline low now
dont rush into increasing TA as 50 is ok
swg must be turned off when adding salt and for 12-24 hours after
again will impact your fc level

To add to what Aussieta said, when adding cya be sure to go ahead & dose with liquid chlorine to reach target fc (not minimum) or a dab above for your new intended cya immediately. Then allow your swg to maintain. Swg’s are great maintainers but they take too long to add appreciable amounts of fc & you don’t want anything brewing or getting its foot in the door while you wait for the swg to catch up.
As you determine/adjust your appropriate run time/% do the same, dose w/ lc 1st then see if the swg maintains that level. A little extra fc is fine & harms nothing but if fc falls too low you risk algae.
Many here, myself included, maintain fc a little above target all the time- this allows for me to be covered in the event of a high uv day, heavy bather load, equipment malfunction etc.

Update: All planned treatment completed in baby steps (i.e. 50% to 60% of required levels of CYA & Salt). Since this was my first ever attempt, wanted to be extra careful. Performed a complete test today after 60 hours since the start of the treatment.

Treatment & Test Results:
On 9/27/22: FC = 3; CC = 0.5; pH = 8.0; TA = 50; CH = 475; CYA = Not Tested; Salt = 1600
On 9/29/22 (just before the start of the treatment): FC = 4 ppm; CC = 0 ppm; Salt = 1600 ppm; CYA was not tested due to R-0013 unavailability.
Added 2 lbs of dry stabilizer; 160 lbs of Salt; 0.5 gallons of 7.4% bleach. SWG was off & Pump/Filter was set to run 24 hours.
On 9/30/22 (after 24 hours of pump runtime): FC = 3 ppm; CC = 0; Salt = 2600 ppm; CYA was not tested as it wasn't 48 hours yet.
Turned on SWG and set pump/filter to normal schedule i.e. 10 hours over night.
On 10/1/22 (after 60 hours after treatment): FC = 4 ppm; CC = 0; pH = 7.8; CYA = 50; Salt = 2600 ppm; TA = Not tested as PoolMath indicated no impact; CH = Not tested as PoolMath indicated no impact.

Next Steps:
* Add 80 lbs of Salt which per PoolMath adds 562 ppm taking the Pool's Salt to 3100ish ppm.
* Add 2.5 lbs of Dry Stabilizer which per PoolMath adds 18 ppm of CYA resulting finally in 60~=70 ppm. Also lowers pH by 0.3 resulting finally in 7.5.
* Test TA to confirm whether it remains at 50. If yes, add 5 lbs of Baking Soda (no impact to pH under 6 lbs of Baking Soda w.r.t my Pool per PoolMath) adds 21 ppm resulting finally in 70 ppm.
* Test FC w.r.t CYA and figure out next steps to update SWG output which is set to 50% as of now.

Question:
1. Any specific instructions on how to add Baking Soda? Can it be added along with CYA & Salt or needs an ordered sequence?
2. Curious to know whether it is a must to run pump for 24 hours continuously or it is OK to add CYA using my normal run schedule i.e. 10 hours runtime every night. Meaning, the CYA will get mixed into the pool gradually over two nights instead of next 24 hours. I'm in no rush but at the same time I don't want to sabotage the treatment. Please let me know your thoughts.
