Use ozone instead of chlorine

GetOzone offer the Aquazone Range of Atmospheric Air fed Corona Ozone Generators which are ideal for Residential and larger swimming pools.
The Aquazone Basic units as per the picture above have no Flow metre or Air driers which are included in the Aquazone Advanced range.

Ozone works 3000 times faster and is 1.5 times stronger than chlorine so is a very effective replacement for chemicals without the harmful effects of chlorine. The water in a properly ozonated pool will taste or smell similar to rain water with no chemical or other taints.
However its effectiveness is dependant upon a few factors which must be accounted for by the installer or user.
Ozone has no residual capabilities as it reverts back in to oxygen 20 minutes after exposure to water or air and therefore has to be introduced continuously in to the pool to maintain cleanliness.
· It is advisable to operate the pump circulation system and ozone generator 24 hours per day for maximum effect when no additional chemicals should be required
· For lesser running periods it is advisable to treat the water with a chemical such as chlorine in the “still” areas in the pool on a fairly regular basis. (this is normally 10 to 15% of normal chlorine consumption). In order to achieve the recommended pool turnover the running time of the pump will have to be increased ( from , for example, 8 hours per day to 12,) as the in line venturi restricts the water flow.
· Efficient mixing of the ozone gas in to the water is important to achieve maximum effect and the venturi will suck the gas in and also cause a turbulence improving the effectiveness of the mix. A static mixer or contact chamber (not supplied) will also improve the effectiveness of the ozone.
· Contact time is also important and the piping between the venturi and pool inlet should be no less than 10 metres if no contact chamber system is used.
· The higher the temperature of the water, the more ozone will be required.
· A converted pool from chlorine is likely to turn green in the first few days due to the oxidation effect of the ozone and the resultant floaters in the water. It will take a while for the filter to clean the whole pool so to avoid this treat the pool with 5 litres of bromine before operating the ozone system.

  1. Plumb the 50 mm Venturi in to the supply water line after the filter and as far away from the pool inlet as possible.
  2. If using a contact chamber plumb and fit after the venturi to enable extra time for the ozone gas to mix with the water before being reintroduced to the pool.
  3. Mount the wall mounted ozone generator in a cool, clean and dry position where the connections can easily be made. (The unit should be higher than the pool or filter to prevent backflow of water in to the generator).
  4. Connect the silicon or hard PVC 6 mm tube to the ozone outlet and to the venturi.
  5. Run the pump and check that there is suction at the the ozone generator.
  6. Connect the power cable to the electricity supply of the circulation pump so that when the pump is not running the ozone generator will also switch off.
  7. Switch on the pump and check all gas and water connections.
  8. Switch on the ozone generator through the switch on the front.
  9. Check for bubbles at the pool inlet to ascertain if the venturi is working.
  10. Check for the smell of ozone at the venturi inlet and pool inlet.
  11. Check the generator is running cool and that the cooling fan is operational.
  12. The Aquazone ozone generator can vary in size from 1 gram ozone per hour to 10 grams ozone per hour using atmospheric air as the feed gas.


  • Once per day check that there is suction at the venturi by removing the gas piping to the venturi and feeling with finger or thumb to see if there is suction. Bear in mind that a dirty filter or “barracuda” attachment will affect the water flow and therefore the suction at the venturi.
  • Replace the non return valve once every 3 months.
  • Clean or replace the air filter pads whenever necessary.
  • Send the ozone generator in for cleaning and checking once per annum.

Remove the lid and scrub the contact chamber clean from time to time.


  • No ozone
    Check power to generator.
    Switch on and check fuse.
  • Check cooling fan working
    Clean filter pad.
  • Look for water or dirt in the ozone line.
    Clean by blowing air through.
    Return the generator for checking.
  • No suction at venturi
    Check main water flow sufficient.
    Increase flow through the venturi by adjusting the valve.
    Confirm the pipe or venturi inlet is not blocked or restrict
    Thoroughly backwash the filter.
  • Smell of ozone at pool inlet.
  • Inadequate mixing of ozone gas in to the water.

Fit in line static mixer or contact chamber to improve mixing.
Inadequate mixing time.
Loop the supply line or fit a contact chamber to allow extra mixing/contact time before delivery in to the pool.

  • Pool going green.

Insufficient ozone.
Increase running time or chlorine dosage.
Fit larger output ozone generator.

  • Inadequate mixing.
    Fit in line mixer or contact chamber.
