Steve, chlorinated water may be, might not be, etc. We need to look further.
The religious pool I described, for religious reasons, is NOT allowed to use treated water. Naturally, since the design is at least 3000 years old, they have some reason to believe that their rules have stood the test of time.
Another customer has a pool that is NOT chlorinated, at all. They treat with ozone.
Pool rules can also come into play with ornamental ponds, which may have plants and fish in them. Something to consider.
