In this symbiotic environment fish feed on the aquatic plants and microorganisms obtaining much of their nutrients. The plants produce most of the oxygen for the system. These conditions, combined with the unique permeable membrane plug, allow the plants and fish to support each other in the Omnarium. The plants in the Omnarium are very important in utilizing fish waste. Naturally occurring bacteria breakdown the waste material converting it into available nutrients for the plants.
Snails perform an important role by eating the dead plant material.
Another important feature of the Omnarium is the rotary base, which acts to stir the water and release nutrients. This stirring action moves the water and nutrients making them available to the plants and snails. Do not pick up the Omnarium Dome from its sides. Pick up only from the Rotary Base. Picking your dome up by the sides may cause the base seal to leak, or cause the base to come off due to the weight of the water.
