Title: SYSTEM FOR FISH TANK CLEANING AND METHOD THEREFOR
Abstract:
A fish tank includes a first water chamber for providing living space for fish; a second water chamber in fluid connection with the first water chamber with a grating therebetween. The openings of the grating are sized to keep the first water chamber and the second water chamber fluidly connected but prevent fish or other aquatic animals from entering the second water chamber. In an embodiment, a one-way valve allows water to flow out of the second water chamber and prevents water from flowing back into the first water chamber. A removable syringe with a plunger, a barrel and an orifice is provided such that when the orifice is connected to the one-way valve means and the plunger is pulled out of the barrel, water in the second water chamber flows into the barrel of the removable syringe through the one-way valve means.
