ABSTRACT:
An aquarium system consist of an open topped fish tank, a base cabinet stand and an encased cover, wherein unclarified aquarium water is drawn downwards by gravity and filtered below the tank, while being aerated and heated as it is returned to the tank in a waterfall fashion.
The tank includes removable gravel support grating trays, a funnelform bottom and a drain.
The stand houses a main shut-off valve, a clean out trap, a filter tank with a removable cap and fiber housing, along with a holding tank and water pump.
The cover encasement houses a light, an aerator, a water compartment and guide tray, as well as a programmable timer to control the on/off functions of the water pump.
In operation, unclarified water in the tank is drawn downwards by gravity and is filtered once as it passes into the drain, and again in the filter tank, before being pumped into the water compartment.
In the water compartment, the newly filtered water is accumulated until it flows downwards along the guide tray, creating a waterfall effect, while being aerated and heated as it passes back into the tank.
This entire system is controlled by a programmable timer, which enables the filtering process to be repeated at predetermined intervals daily.
