When to switch PoolMath?

[TwinMama15]

My brand new plaster pool was filled on Thursday. I am using the Bleach setting on PoolMath because salt won't be added to the pool for 30 days. When do I switch to the "SWG" setting on PoolMath? I don't know when I should get to those levels in preparation for using the SWG compared to manually adding bleach. Thanks in advance!

Switch when they add the salt.

(Keep up with your manual additions of chlorine....it's getting hotter!)

Thanks! Should I up the CYA levels in advance since they take longer to show up on testing?

Right now, my target is 30-50, but that will go up with SWG. Although, I might be over anyway because my PB added in CYA already, about 96 oz from my estimation (and not via the sock method, just direct to skimmer). PoolMath says it would've taken 77 oz to get to 50, so hopefully I'm not too over....thoughts?

Up the CYA after they add the salt and then simply assume your dosage is correct. Test it a few days after the addition to double check your dosage.
