A2Z Ozone SP - Series - Manual (Page 17)

15) 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.
16) 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 better 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 24hrs a day in 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.
17) 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
material, 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 a definite "clarity and sparkle" that you may not
have experienced before. In addition, after the ozone does its work, it reverts back to oxygen.
This added oxygen will make the water look, feel and even taste better.
18) How should I prepare my pool before I install an ozone generator?
• Backwash Pool
• Adjust total alkalinity with Hydrochloric acid or Sodium Bicarbonate 80-100ppm
• Adjust pH 7.2 to 7.8 (HCL acid to lower and Sodium Bicarbonate to increase )
• Shock treat with Hydrogen Peroxide 35% ( 100mL / 1000 Liters pool water )
• Ozone is used as primary Sanitizer and Sodium Bromide as secondary / residual Sanitizer
• Sodium Bromide should test between 1-2 ppm (Dosage: 20g per 1000 Liters of water
every 6 months)
19) What special swimming pool maintenance ozone systems require?
• Shock treat with Hydrogen peroxide
• Maintain total alkalinity with Hydrochloric acid or Sodium Bicarbonate 80-100ppm
• Maintain pH 7.2 to 7.8 (HCL acid to lower and Sodium Bicarbonate to increase )
