Abstract
A combination of a physical filter and aerobic filter positioned entirely on the outside of an aquarium tank. Water is pumped into the physical filter chamber and upon reaching a level above the chamber walls of the physical filter it spills by gravity flow to both an aerobic filter also contained within the housing and back into the aquarium tank. The water entering the aerobic filter is filtered and passed back to the physical filter where the filtering is repeated.
Claims15
A combined physical filter and aerobic filter contained in a single housing for physical and biological filtration of contaminated aquarium water in an aquarium tank, comprising:
- a filtering chamber containing means for physical filtration of aquarium water, said filtering chamber having first and second spillways positioned on a top side thereof through which filtered water overflowing the filtering chamber exits by gravity flow;
- pump means for pumping contaminated water from the aquarium tank into said filtering chamber;
- an aerobic chamber containing a medium supporting aerobic bacterial growth and positioned to receive the filtered water exiting the first spillway;
- means for delivering water exiting the aerobic chamber directly back to the filtering chamber, the means for delivering being positioned within the housing;
- means for attaching the combined filter to an exterior side wall of the aquarium tank positioning the second spillway to overhang the exterior side wall of the aquarium tank thereby delivering the filtered water exiting the filtering chamber back to the aquarium tank by gravity flow.
An aerobic filter means for biological filtration of contaminated aquarium water in an aquarium tank in combination with a filter means for physical filtration of aquarium water, the combination comprising:
- means for positioning both the aerobic filter means and filter means for physical filtration entirely on an exterior side wall of the aquarium tank;
- means for conducting the water exiting the filter means for physical filtration to both the aquarium tank and the aerobic filter means, said means for conducting being positioned on a top side of the filter means;
- and
- means for drawing water from the aquarium tank and delivering the water drawn to the filter means for physical filtration, wherein the means for drawing also collects water filtered by the aerobic filter means and delivers the filtered water directly to the filter means for physical filtration for being physically filtered an additional time.
