Now don't laugh but...does it smell like a real lake? For what it's worth, I'm in North TX and occasionally get a whiff of a "real lake" smell from the pool. Crystal clear water and good numbers (thanks to members of this forum).

I finally made the connection that the smell comes after I've added water to the pool. Our local water supply gets an off-aroma from time to time in the heat of the summer. Supposedly, it's because our supply comes from 2 lakes that can have algae issues and the water has to get treated a certain way at the water plant.

City water officials say the water is A-OK to drink and use, but definitely has an aroma from time to time.
