ABSTRACT:
1. FIELD OF THE INVENTION
This invention relates to cleaning aquarium water and aquariums by removal of contaminants and objectionable material quickly, easily and without making a mess.
2. RELATION TO PRIOR ART
Keeping aquarium water and aquariums clean has long been and remains a major burden for aquarists. Consequently, there are numerous known aquarium-maintenance devices, systems and methods, but none having the convenience, ease and cleanliness of operation made possible with this invention.
An example of a known related but different aquarium-maintenance system is described in U.S. Pat. No. 5,866,018, issued to Hyde et al on Feb. 2, 1999. Hyde et al taught a vortex aquarium filter which flung particulate in fluid outward radially with vorticity against a cylindrical wall where it became sludge which gravitated down to a tapped outlet. Slightly cleaner and easier to use than some, it still required messy and tedious disposal of aquarium particulate that was flung off and collected. Also known are throwaway filters, reverse-flow cleanable filters, screen filters and other filters that are not part of an aquarium-maintenance system as taught by this invention.
SUMMARY OF THE INVENTION
Objects of patentable novelty and utility taught by this invention are to provide an aquarium-maintenance system which:
cleans most known aquarium filter components easier, faster and cleaner;
provides visual display of cleanliness of aquarium water en route to, from and in a filter; and
flushes aquariums selectively and optionally in combination with filter cleaning.
This invention accomplishes these and other objectives with an aquarium-maintenance system having a transparent filtering canister with quick-joint inlet attachment and quick-joint outlet attachment to transparent aquarium tubing, together with a handle to allow quick, convenient and clean replacement and/or back-flow cleaning of filtering members. A system pump has variable output capacity for filtered water circulation and optionally for aquarium flushing with a cannister bypass, valved conveyance to a drain-water disposer, valved conveyance from a refill-water source and valved conveyance from a wash-water source. This is a comprehensive aquarium-maintenance system that is adaptable totally or in part to all sizes and types of aquariums.
