Should I salt my pool?

[Sherra]

How many ppm is a good amount for a non-SWG pool?

It depends on the level of stabilizer (CYA) in your water. See this thread for a "guide".

Court, did you mean ppm of salt?

If so that's independent of CYA levels.

I could tell a water quality difference at 1200 ppm. Anywhere from there up to 3000 ppm should do.

Start at around 1000 and add more as you feel necessary after you've had a chance to swim around and judge it for yourself.

Range, you're right...it slipped my mind that we were talking about salt! When I see ppm my mind automatically shifts into chlorine mode!
