Power Aquarium Cleaning and Gravel Vacuum

Abstract

A gravel vacuum, including a pump, a detachable suction base connected to the pump to which a suction tube can be attached, a filter connected to the suction base, a return assembly, at least one valve, and an alternate flow path. The pump impels a flow of water from the suction base, through the filter, and out the return assembly. The valve permits adjustment of volume of the flow for different sizes of fish aquariums. The alternate flow path reduces back pressure on the pump when the valve is used to adjust the volume of the flow. Also, a method of using the gravel vacuum.

1 . A gravel vacuum, comprising:
 a pump;   a detachable suction base connected to the pump to which a suction tube can be attached;   a filter connected to the suction base;   a return assembly;   at least one valve; and   an alternate flow path;   wherein the pump impels a flow of water from the suction base, through the filter, and out the return assembly;   wherein the valve permits adjustment of volume of the flow for different sizes of fish aquariums; and   wherein the alternate flow path reduces back pressure on the pump when the valve is used to adjust the volume of the flow.   
   
   
       2 . A gravel vacuum as in  claim 1 , further comprising a suction tube attached to said suction base, the suction tube having sufficient diameter for gravel to fit inside. 
   
   
       3 . A gravel vacuum as in  claim 2 , wherein different length suction tubes can be attached to the suction base. 
   
   
       4 . A gravel vacuum as in  claim 1 , further comprising a strainer in the suction base. 
   
   
       5 . A gravel vacuum as in  claim 1 , further comprising a squeezable suction pump by which the cleaner can be primed. 
   
   
       6 . A gravel vacuum as in  claim 1 , further comprising a pre-filter assembly that the water flows through before the filter. 
   
   
       7 . A gravel vacuum as in  claim 6 , wherein the pre-filter assembly includes an intake assembly connected by a male/female disconnect system. 
   
   
       8 . A gravel vacuum as in  claim 7 , further comprising a shut off valve that decreases a chance of water spilling out during disconnect of the intake assembly from the pre-filter assembly. 
   
   
       9 . A gravel vacuum as in  claim 7 , further comprising a drain assembly between the intake assembly and pre-filter assembly. 
   
   
       10 . A gravel vacuum as in  claim 1 , further comprising a gravel trap that protects a motor in the pump. 
   
   
       11 . A gravel vacuum as in  claim 1 , further comprising a pre-filter for the filter and a gravel trap that protects the pre-filter. 
   
   
       12 . A gravel vacuum as in  claim 1 , wherein the filter includes a carbon container for detoxification of the water and a minimum twenty (20) micron filter for the removal of fish waste and food debris from the water. 
   
   
       13 . A gravel vacuum as in  claim 1 , further comprising a shut off valve to assist when disconnecting the return assembly from the filter tower. 
   
   
       14 . A gravel vacuum as in  claim 1 , wherein the return assembly is adjustable and includes a return tube and a diffuser. 
   
   
       15 . A method of using a gravel vacuum, the gravel vacuum including a pump, a detachable suction base connected to the pump to which a suction tube can be attached, a filter connected to the suction base, a return assembly, wherein the pump impels a flow of water from the suction base, through the filter, and out the return assembly, the method comprising the steps of:
 attaching a suction tube to the suction base;   immersing the suction tube into an aquarium;   turning on the pump;   inserting the suction tube into the gravel;   whereby the gravel in the suction tube is cleaned while still in the aquarium.   
   
   
       16 . A method as in  claim 15 , wherein the gravel vacuum further includes at least one valve, and wherein the method further comprises using the valve to adjust a volume of the flow. 
   
   
       17 . A method as in  claim 16 , wherein the gravel vacuum further includes an alternate flow path, and wherein the alternate flow path reduces back pressure on the pump when the valve is used to adjust the volume of the flow.
