Is ozone safe for swimmers?
Ozone is dissolved in the water in pH neutral so the pH will not harm equipment or people.
The amount of ozone added to the water is enough to kill bacteria, virus, cysts, mold and
spores, but is safe and non-toxic to humans and pets – no red, irritated eyes and dry, itchy
skin. When properly installed and plumbed all of the ozone generated will be dissolved in
the water or used up oxidizing impurities in your water.
Does ozone affect water balance?
Ozone has a neutral pH (about 7.0) so it does not affect pH. Ozone has no calcium, no
alkalinity, and no dissolved solids. Therefore, ozone does not affect water balance. It does
remove trace amounts of metals such as iron or copper by oxidizing them to their highest
oxidation state. They will then precipitate out of the water and be trapped by your filter.
Can I run my pump and filter for fewer hours?
Ozone is only injected into your water when the pump is running. The longer you run the
ozone generator (And your pump and filter), the best your resultant water quality will be
and thereby reducing the need for residual chemicals. During summer/swimming season
you should run your ozone generator, pump and filter a minimum of 12 hours each day. We
recommend that you run your pump for 24 hours a day in the summer. Up to 80% of the
water treatment is done by your filter, so don’t be afraid to use it. The extra electricity cost
will be compensated by the savings on costly chemicals.
Will there be a visible change to my water?
Yes, when ozone is first introduced into your pool water and during the first 72 hours, your
pool water may get cloudy. Ozone will begin to oxidize all of those particles and metals
that your present sanitizer would otherwise leave in your pool. When these particles are
oxidized, they form visible particles that are heavier than water and precipitate. Also, there
will be pieces or fragments of the cells that ozone has destroyed. So the cloudiness that
you may see is oxidized materials, pieces and fragments of cells, and metal precipitates.
Some of the dirt and debris in the water is too small to be trapped by the filter. These small-
sized dirt particles have a weak electrical charge or pole. Because all the dirt particles
have a negative charge, they repel each other like two magnets. They are so small that they
are not affected by gravity and therefore won’t settle out either. Ozone neutralizes these
charges, which allows the particles to combine into large enough particles to be trapped
by the filter. Once these particles are oxidized, neutralized and filtered, the water will have
