4.3.9 ALGAE:
Algae are microscopic plants which can grow
in a spa if the free chlorine or bromine read-
ings drop too low. It can sneak up on you
without you seeing it. Algae spores are always
in the atmosphere and soil. Rain showers,
winds and dust storms are constantly ~umping
these spores into your outside spa. Sunlight
and warm temperatures provide th~ ~Iimate
for algae to reproduce and grow -and grow.
When you can see them you already have
about 30 million algae per ounce of water.

3. ozone ~ Is "most -friendly"- to the
environment because, unlike chlorine, it
introduces ~o forms ~ 91 tP~ic Qr ~reactive
by-products.
4. Ozone, unlike chlorine, leaves no foreign
chemicals remaining in the water.
5. No by-products other than oxygen, carbon
dioxide, and filterable remains are geflerated by
using ozone.
ENJOY YOUR SPA!
The best way to take care of algae is to never
let it appear. Diligent testing is a great preven-
tative along with the use of an algaecide.
Treatment consists of supercholorination and
an algaecide appli~tion.
4.3.10 ALTERNATIVE DISINFECTION METHODS
The spa industry is unique in that its end
product. the spa, in its most basic definition, is a
vessel which. when filled with water, heated to
the recommended temperature for safe use,
second, then allowing that water t~ move around
a person's body, creates a pleasurable,
therapeutic environment. Unfortunately, this.
same water becomes saturated with
contaminants and bacteria.
Primarily, there are three methods of disinfecting
the spa water. The first, and most widely used, is
chlorine disinfection. Atthough powerful and
effective, there are some adverse si~e effects:
strong odor, limited life, strong irritant. very
unstable. The second, bromine, although not as
strong as chlorine, has minimal odor, is more
stable, and is less of an irritant. The third
alternative is ozone. Although it is 50% more
powerful than chlorine and 90% more powerful
than bromine, it has not been as popular as the
first two disinfectants, due to its relatively new
introduction in the market. Howeveri it is fast
becoming the recommended method of
disinfection for the following reasons:
1 .Disinfection takes place at a much higher
oxidation level. In fact, there are no bacteria or
"Iruses that are resistant to ozone.
