Aquarium

Marine life exhibits at aquariums and amusement parks present a challenge to water quality operators charged with their care. Because such large volumes of water flow within these systems, a flow-through system continually replaced with clean municipal water is not economical or practical. Additionally, the colorful fish that the public prefers to see live in a salt water environment which has a cost to support in non-coastal areas. Therefore, exhibit waters must be continually recycled through a life support system (LSS) to protect the animals in the exhibit, as well as maintain adequate water quality for aesthetic purposes.
 

Ammonia and its nitrogen derivatives are of crucial importance in aquariums due to toxicity to fish, and in marine parks due to combined compounds which irritate soft tissues of marine mammals. Ammonia, nitrite and nitrate offer no benefits and only reduce water quality with increasing concentrations.

In aquariums of any scale, mechanical filtration will remove large organic and inorganic solids, and biological filters will remove dissolved organic material in the form of Ammonia and Nitrite, this still leaves behind a large number of other dissolved and colloidal organic materials that will accumulate over time (the ones causing colors and odors being most noticeable). In most cases these materials are only removed by physical water changes, or chemical absorption media. While frequent water changes may be practical for removing these dissolved materials in smaller aquariums where you are not dealing with large volumes of water, it is not a practical method for removal of these materials in large systems or in systems where water conservation is at a premium. Using chemical absorption media is expensive, and is limited in its ability to remove all of these undesirable dissolved organics.

Key Benefits Of Ozone: -

• The role of ozone in aquarium waters is from the perspective of ensuring water quality parameters are within desired range. Water quality needs include not only providing crystal clear disinfected water for viewing, but also oxidation of organics, inactivating bacteria and virus populations, and minimizing or eliminating chloramines formation.
• Removal of complicated dissolved organics that cannot be handled by ordinary bio-filter. The ozone oxidizes them and breaks them to simple organics that are now available for degradation by heterotrophic bacteria.
• Reduction of harmful ammonia (NH3-) and nitrite (NO2-) levels by oxidizing them to nitrate (NO3-).
• Algae control.
• Destruction of harmful inorganic components, such as sulfides.
