Allen, here in Calif, bees in pools and hot tubs are one of my most
insoluble problems.
I've watched bees fly over ponds to seek out a hot tub--they seem to be
strongly attracted to the chlorine, sodium, or something.
I, too, was eagerly watching this thread for practicable solutions!

In order to train bees away from a water source, one must cover, screen off,
drain, etc the source until the trained foragers die from old age (about 2-3
weeks).  The bees must be offered good alternatives during that period.

I've noticed that entire yards will get water at the same tiny point along
the edge of a pool--there is apparently a pheromonal attraction.

I'm sure that you knew all the above--wish that I could have been of more
help!
