Ozonizers are used in the marine aquarium in order to optimize the skimming by the skimmer. The ozone produced is the strongest oxidizing agent and able to break down specific substances and provide them to the skimmer. Thus it has an intensive impact on the nitrogen cycle in the aquarium. It includes e.g. humic substances which makes the water yellowish and also nettle toxins. The water is always crystal clear with ozone use. On our online shop you will find ozonizers manufactured by all the known manufacturers for use in the marine aquarium.
