UNDERSTANDING WATER BALANCE
Water balance is the interrelation of factors that
determine the quality of the spa water. The effective-
ness of chemicals and other additives are dependent
on all these factors working together or "in balance".
The primary elements to water balance are sanitizing,
monitoring pH and alkalinity levels, and oxidizing or
shocking.
Before we begin, it's important to understand that a
spa is not just a "small swimming pool" and that the
care of a spa needs to be handled differently. In
addition to the fact that a spa is kept at a tempera-
ture of up to 104°F (40°C) and pool chemicals are
designed for cool water, the ratio of people per gallon
in a spa is also very different. Four people in a spa is
the equivalent of having 200 people in a typical
backyard pool. This increased "bather load" in-
creases the residue from soaps, perfumes, body oils,
cosmetics, and other contaminants. Always use
water treatment products designed for spa use.
Sanitizing Methods
All Marquis spas are equipped with the exclusive
Marquis Ozonator. The use of an ozonator greatly
reduces the amount of chemical sanitizer you need in
the water. Ozone works by delivering activated
oxygen gas into the spa water via an ozone injector
fitting. The ozone gas combines with contaminants to
sanitize the water. Although sometimes promoted as
a stand-alone chemical free alternative, we recom-
mend that you maintain a small residual of bromine (or
chlorine) in the water while using any ozone system.
Supplementing the water with sanitizer controls and
prevents bacteria growth. Instead of the normal 3 - 5
ppm of sanitizer recommended, you only need to
maintain a 0.5 ppm level of bromine (or chlorine) when
using an ozonator.
Only the use of ozone, bromine (or chlorine if not
using the Spa Frog® system) are recommended. Use
of other alternative sanitizer systems may void the
warranty. Important: Cal Hypo and TriChlor
compounds are not recommended for use with
a Marquis spa.
