do you need to turn off SWG when adding chemicals

Yeah, people who tell you to shock every 2-3 weeks without testing are idiots. If you don't have either of the problems I mentioned above, then there's simply no need to shock, other than to wear out your cell faster, or spend money on shock.

How big is your pool?

Before adding salt you should double check your salt reading because the SWG read out my not be correct. I use test strips and also have a local pool store give me a read with their hand held guage. There will usually be some variance between test readings...but you should have a pretty good idea of the salt content by using all three readings.
