A method of treatment of water in an aquatic environment. Water is first pumped
from a reservoir to a first mixing station. An inert gas is introduced into the
pumped water at the first mixing station to provide inert gas saturated water,
which inert gas saturated water will displace undesired gasses in the water in
the reservoir. The inert gas saturated water is then pumped to a sparging column
such that the inert gas and undesired gasses will be released from the inert gas
saturated water to provide depleted water. The depleted water is then pumped to
a second mixing station, wherein oxygen is introduced into the depleted water to
provide oxygen enriched water. The oxygen enriched water is then returned to reservoir.
