Maintaining a very high level of oxygen in a pond or water garden is critical. The oxygen content in the pond is subject to heavy fluctuations. Plants and algae which produce oxygen during the day through solar energy switch their metabolism at night and use up most of the available oxygen. This natural process depletes almost all of the oxygen supply. Therefore, the survival of the fish and other organisms is especially endangered during the early hours of the day.
