Aquarium siphon

Abstract

A siphon for siphoning water from an aquarium into a bucket includes a siphon tube having a first end for insertion into the tank and a second end for insertion into the bucket. A first pair of magnets is provided for releasably attaching the siphon tube to the tank and a second pair of magnets is provided for releasably attaching the siphon tube to the bucket. The siphon further includes a magnetic float valve for closing the second end of the siphon tube when the water in the bucket reaches a predetermined level.

1 . A siphon for siphoning water from an aquarium into a bucket, comprising:
 a siphon tube having a first end for insertion into the tank and a second end for insertion into the bucket;   means for releasably attaching the siphon tube to the tank;   means for releasably attaching the siphon tube to the bucket; and   means for closing the second end of the siphon tube when the water in the bucket reaches a predetermined level.   
   
   
       2 . A siphon for siphoning water from an aquarium into a bucket, comprising:
 a siphon tube having a first end for insertion into the tank and a second end for insertion into the bucket;   magnet means for releasably attaching the siphon tube to the tank;   magnet means for releasably attaching the siphon tube to the bucket; and   magnet means for closing the second end of the siphon tube when the water in the bucket reaches a predetermined level.   
   
   
       3 . A siphon for siphoning water from an aquarium into a bucket, comprising:
 a siphon tube having a first end for insertion into the tank and a second end for insertion into the bucket;   a first pair of magnets for releasably attaching the siphon tube to the tank;   a second pair of magnets for releasably attaching the siphon tube to the bucket; and   a magnetic float valve for closing the second end of the siphon tube when the water in the bucket reaches a predetermined level.   
   
   
       4 . A siphon according to  claim 3 , wherein the second end of the siphon tube includes a first magnetically attractive element and the magnetic float valve includes a float having a second magnetically attractive element, the float being responsive to the level of water within the tank for lifting the float for moving the second magnetically attractive element into sealing engagement with the first magnetically attractive element to prevent any further water from being siphoned from the aquarium into the bucket. 
   
   
       5 . A siphon according to  claim 4 , wherein one of the magnets of the first pair is mounted on the aquarium while the other is mounted on the hose, and one of the magnets of the second pair is mounted on the bucket while the other is mounted on the hose. 
   
   
       6 . A siphon according to  claim 4 , wherein both magnets of the first and second pairs of magnets are each mounted on the siphon hose.
