I don't know why ozone in a hot tub that's the way the hot tubs were being
sold? I had never heard of it and am wondering if it puts out ozone into
the air and if there is any other concerns I SHould know about. Of course
the sales person said it was perfectly safe.
need for some spa chemicals, but it also has it's own costs.
One being the initial cost of the ozone unit, and another being replacement
elements. The less expensive ozone units have relatively expensive bulbs,
that may need to be replaced yearly, give or take.
The more expensive units (Corona discharge) last many more years without
So I'm not really sure in the long run which is less expensive. For now
were sticking to the chemical system, ours gives us excellent water quality,
and isn't really too expensive.
Interesting observation about possible premature aging of plastic. I
haven't seemed to have that problem in my tub. I just replaced my
cover after 5 years. Most Spa techs seem to think a cover is good for
between 3 - 4 years, so I think the ozone isn't hurting anything. It's
a pretty trivial amount of ozone being introduced in any case.
I use a 2 part bromine system, and the ozonator cut my chemistry
amounts by more than half. I have the lamp type ozonator, and at 5
years, the lamp is still working, and has not needed replacement. I
can replace the whole ozonator for about $200, or the lamp for a lot
less, so it has paid for itself several times over in chemistry
savings. Naturally, the amount of use you tub gets, how precise you
are about water balance, and other factors will all affect results.
