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.
