Celebrating over 20 years in the industry, Nature2 purifiers have become one of the greatest success stories, rivaled only by Polaris perhaps. Now owned by Zodiac, (who also owns Polaris) - Nature 2 has expanded their line of mineral purifiers for pools and spas, and also coupled the Nature2 technology of Cationic Sanitation with Salt Chlorine Generators.
Early use of metal ions for pool purification were electric devices, with plates of dissimilar metals, usually copper and silver. Applying electricity to these plates causes the charged metal ions to jump off towards an opposite charged plate, where it is swept away by the water current in the pipe. Use of such systems like Caribbean Clear do have sanitizing properties, but misuse by homeowners can lead to a staining problem. The cells also required maintenance, and the overall system was costly to install.
The engineers at Fountainhead Technologies
originally set out to develop a non-electric
ionizer. This would be accomplished with a
metallic cartridge which would erode itself
from the passage of water flow over it, thereby
giving off its ions to the water. After years
of testing, they had discovered something much
more. In operation, the aluminum and silver
cartridge causes dissolved oxygen in the water
to separate into individual nascent oxygen
atoms. These individual oxygen atoms are one
of the world's most powerful sanitizers, destroying
anything in its path as it tries to re-combine. So,
we have an ionizer that also brings a catalytic
reaction to oxygen molecules. Sort of like
an ionizer and ozonator all in one.
Nature2, and it's competitor the Frog System, by King Technologies don't market these purifiers as sanitizers, nor do they suggest it as a replacement for chlorine. They do suggest
that it greatly reduces reliance on and enhances
the effectiveness of traditional methods and/or
other alternative methods such as ozone. Its performance is enhanced
with the use of enzymes.
Zodiac, the manufacturers of Nature2, recommend
the periodic use of a non-chlorine
shock, and a polyquat algaecide, used in
Recipe. Nature2 is more commonly used with
a small amount of chlorine (.4 - .6 ppm) quite
effectively. This is outlined in their Low-Chlorine
