It's not a "method".

You may be thinking -- because some people talk as if it's so -- that there is a way to treat pools with salt alone. That is NOT true! Salt + an SWCG is just a METHOD of adding chlorine.

Some people add salt, while still chlorinating through other means, because they like the 'feel' and because it lowers eye irritation compared to 'fresh' water. But that's all. Salt alone does NOTHING to sanitize a pool or prevent algae. If that's what you mean by "method", there IS no method.

Good luck,
