Drained pool, added a swg, start up help needed

[Dreamweaver2023]

Am having my pool drained today, tile/grout repair and a circupool rj60+ installed.
Need some recommendations on a startup procedure, estimated to be adding about 400 pounds of salt.
Should i use tablets to raise the CYA? What level CYA thru winter?

Any suggestions are much appreciated.

400 lbs of salt should give you around 3200ppm.

Add CYA with dry stabilizer using the sock method. 8 lbs of stabilizer will give you CYA of 60-70.

pH in the 7's and add 1 gallon of 10% liquid chlorine to get your FC 6-7 and start up your SWG after the salt circulates and dissolves for 24 hours.

THX AJ.
Just tested my current(before draining) pool water and tap water.
Pool Tap
Cl 3 <0.5
Ph 7.8 7.8
CH 350 275
TA 110 120
CYA 100 visible with tube full

I still am not comfortable doing the CYA test, do you fill until the dot starts turning gray or until it disappears completely?

Do you heat your pool? What is the temperature of your water, and/or what do you expect it will be through the winter? Are you expecting much rain in the winter months?

I drained and refilled my pool once, about this same time of year. And I had an SWG. But I held off on adding salt and a bunch of CYA until the Spring. In my area, an SWG will not produce chlorine because of the <50° water temp. So I waited until Spring to add the salt and the rest of the CYA. Winter rains would have sent those chemicals into my overflow, down into my yard. There was no point in me getting the water "SWG-ready" when I couldn't run my SWG. So I added just enough CYA to get it to 30, and no salt. Come Spring, I added more CYA to get to 70, then added my salt, waited a few days, then fired up the SWG.

During winter, I just ran my pool as a "non-SWG" pool.

If you heat your pool, or it naturally stays above 55° all winter, then it would be a different strategy.
