I've heard the threshold for tasting salt in the water is around 3000 PPM. Last year was my first year with the SWG and I kinda over did it in the spring so I ran a little high all year (about 3400 PPM). This year I’m going to try to keep it around 2800 - 2900 and see how it works. Can't tell if it taste any different still a little cold to swim in MI (burrrr), my dogs haven't complained yet.

When I tell people the pool is salt water they automatically assume sea water and the bad experience they had on vacation. It's no where near the same concentration, I think sea water is around 35,000 PPM. The taste last year was noticeable, especially on hot days when the pool temp was high, but definitely worth the benefits. It's almost hard to detect that it's salt you're tasting, I always warn people that the pool is salt water just so they don't assume the worse when the taste it. If you know what I mean
