Siphon hose with gallon counter

A device for accurately removing a specific volume of water from a personal aquarium comprising:

• a. a base;
• wherein said base is of a wide cylindrical shape and tapers inward and upward;
• b. a hollow cylindrical filter;
• wherein said filter is attached within the section between the base and a volume meter of the base;
• wherein said filter is of a predetermined length;
• wherein the diameter of said filter is substantially equivalent to the diameter of the top of the base;
• wherein the filter has a porosity that excludes common aquarium gravel;
• c. a suction hose;
• wherein the hose has a first and second end;
• the first end extends into the device;
• the second end extends out of the aquarium to remove the water;
• wherein the hose has a predetermined length and diameter;
• d. a plurality of flaps;
• wherein the flaps are located within a region of the volume counter at a predetermined location;
• wherein said flaps rotate with a preset friction;
• wherein the flaps spin in response to the flow of a predetermined volume of water;
• wherein the flaps are fixedly attached to rotate around an elongated pin;
• said pins extend outside of the suction tube and are stabilized on the interior walls of the device;
• e. a volumetric flow display gauge;
• wherein said gauge is fixedly attached to the exterior of the device;
• wherein said gauge is attached to said elongated pin;
• wherein said gauge displays volumetric flow in a desired system of units;
• wherein said display changes in response to the amount of the spinning motion of the rotating flaps.
