What is an Ozone Generator?

An aquarium ozone generator is a device that produces ozone, which is a highly reactive form of oxygen (O3) that can be used to treat aquarium water. Ozone is used in aquariums as a way to improve water quality and reduce the buildup of harmful compounds such as bacteria, viruses, and dissolved organics.

The ozone generator typically consists of a high-voltage power supply that is connected to an ozone cell, which produces the ozone by passing an electrical current through a stream of oxygen. The ozone produced by the generator is then introduced into the water through an injection point, and it can be used to sterilize the water and eliminate harmful microorganisms.

Ozone can be used in different ways to treat aquarium water, such as:

  • Direct injection into the main water flow
  • Using a reactor to contact water and ozone longer
  • Using a venturi-injector to add ozone into the water

Ozone has the ability to neutralize bacteria and viruses, and remove dissolved organics, leading to a reduction of the overall bioload in the aquarium, which in turn can reduce the need for water changes and filter maintenance. Additionally, ozone can also add oxygen to the water, helping to maintain the overall health of the aquarium environment.

Ozone generators should be used with caution as over-dosing ozone can be harmful to the inhabitants of the aquarium as well as the aquarist, also too much ozone can lead to stinging eyes and respiratory issues for aquarists. Properly setting up, using and maintaining an ozone generator is crucial for the health of the aquarium inhabitants and the aquarist.
