I would guess that using the bleach in an AG pool you might be reaching
enough concentration that you would have "salty water". I used bleach
for about 4 years (have since gone to cal-hypo for easier handling) in my
16x32 IG and never noticed a salty taste but did notice the water was
softer over time.

Wally World is handling a SG in some of it's stores now, my brother is putting
one on his AG installation and we'll see how it does.
