The amount of salt we are talking about is typically in the 2000-3000 range of PPM, I believe the ocean or true salt water is on the order of 16,000-20,000 ppm of salt. So it is no where near the concentration of true salt water.

I finally did it this year and I would swear the free CL is more stable. Although we have an indoor pool and with no stabilizer so maybe the salt acts as a stabilizer for the free CL as well?

It definitely made the water feel "softer" and much easier on the eyes as well.

We just dumped in 250lbs the 99.5% pure salt pellets. I turned on the swim jet and they were gone in 15 minutes, I was really surprised they dissolved that fast.
