I've used BioGuard brand (found at Leslie's) without issue. This season there were lots of reports of bad CYA from Walmart which is HTH brand. We never verified it but lots of people complained about HTH brand not registering at all.
As for salt levels, set your level based on your SWG - if you need 3400ppm, add enough salt to get to 3400ppm on the cell output. Don't overshoot unless you expect a lot of rain water dilution.

Awesome! Thanks! I'm sitting right at 3400 (at least according to my pool equipment), so I won't touch my salt. Is there any reason I need to test my salt independently of the equipment (ie test strips)?
I will check the calculator on the site for my CYA and then go down to Leslie's.
The other question I have is filter run time/speed and SWG %. I'm currently running 10-6 (8 hours) at 80% (2760 rpm). Any suggestions or changes there?
