Ozone is similar to oxygen, except where oxygen (O²) has two atoms ozone (O³) has three. This third atom is desperate to join with another atom to become stable. Fortunately for fish keepers this is normally pollutants in the aquarium. Ozone is a very strong oxidation (cleaning) agent, but is environmentally friendly as it made up of three oxygen atoms and therefore does not introduce anything into the aquarium.

Ozone must be used carefully, an overdose could kill all the bacteria in your filter, or in extreme cases directly damage your live stock. It must NOT be introduced directly into the aquarium, it should be introduced via a protein skimmer, or ozone reactor. When using Ozone for the first time the level should be increased slowly and the aquarium monitored carefully to ensure that their are no negative effects.

Installation

An Ozonizer is easy to add to an existing system. If you have an air driven skimmer it connect between your air pump and your skimmer. If you have a venturi or needle wheel skimmer, extend the air suction and add the Ozonizer to the end of the pipe. Ensure your skimmer is ozone safe as ozone can attack some plastics.

Ozonizers should be kept dry at all times for best performance they should not draw in moist air. Air dryers are available to order.

Dosage

The exact dosage will depend on the amount of organic matter & stocking level in the aquarium as a guide start by using a very low level 0.1mg per 5 litres and slowly increase, some aquarium can require up to 1.0 mg per 5 litres of water.
