Abstract
An aerobic filter which comprises a chamber for holding a medium for aerobic bacterial growth. The chamber is positioned to receive filtered water from a primary file which at least physically filters contaminated aquarium water. The chamber is also positioned to be at least partially out of the aquarium water to provide oxygenation of the aerobic bacteria to enhance their growth, and to directly return the aerobically filtered water to the aquarium.
Claims12
An aerobic filter for biological filtration of contaminated aquarium water in an aquarium tank in combination with a filter for physical filtration of aquarium comprising:
- means containing a medium supporting bacterial growth;
- means for positioning at least part of the filter for physical filtration exteriorly of the aquarium tank;
- means for positioning at least a part of said medium containing means interiorly of the aquarium tank while maintaining at least a portion thereof in the air above the aquarium water;
- means for conducting the water exiting the filter for physical filtration to the medium containing means such that all of the exiting water will trickle through the medium by gravity and will be oxygenated as it passes therethrough;
- pump means for pumping contaminated water from the aquarium tank into said filter for physical filtration;
- and
- means for discharging water from said medium containing means into the aquarium tank by gravity.
An aerobic filter for biological filtration of contaminated aquarium water in an aquarium tank in combination with a filter for physical filtration, comprising:
- a filtering chamber positioned at least partly inside the aquarium tank;
- dispersion means for distributing the flow of aquarium water into the chamber so that the water drips through the chamber;
- means for coupling the filtering chamber to the filter for physical filtration so that the filtered water exiting the filter for physical filtration flows onto the dispersion means and therefrom drips into the chamber;
- return means for directing water exiting the filtering chamber directly into the aquarium by gravity.
- pump means for pumping contaminated water from the aquarium tank into said filter for physical filtration;
- and wherein
- said attaching means provides that excess water from the filter for physical filtration will flow over the filtering chamber and will be discharged directly into the aquarium tank.
A combined physical and aerobic filter for physical and biological filtration of contaminated aquarium water in an aquarium tank, comprising:
- a filtering chamber containing means for physical filtering of aquarium water;
- said filtering chamber having a spillway through which the filtered water overflowing the filtering chamber exits;
- 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 spillway;
- means for distributing the water entering the aerobic chamber for trickling through the medium;
- means for attaching the combined filter to the aquarium tank, said attaching means positioning at least part of said aerobic chamber inside the aquarium tank at least partially out of the aquarium water, and for positioning at least part of said filtering chamber on the outside of the aquarium tank;
- and
- means for feeding the water exiting the aerobic chamber directly into the aquarium tank by gravity.
