Biochemical dripping board for aquariums

Claim 2

In a method of cleaning water in an aquarium wherein water from the aquarium is recirculated through a biochemical drip board, wherein the improvement comprises the use of a biochemical drip board formed of a flat board having a plurality of short posts extending down from the bottom, at least a hanger provided at one end of said board, a plurality of holes at the other end of said board, each of said short posts respectively having a very small center through hole, said hole having active nitrate bacteria attached thereto and functioning as a capillary not only to slow down the speed of water flowing therethrough but to increase oxygen contained in the water and further more to cultivate active nitrate bacteria therein in a large number so that organic matters in the water are disintegrated into ammonia and nitrogen, consequently effectively preventing water from worsening.

Claim 3

The method of claim 1, wherein the plurality of holes at the other end of the board opposite the hangers have a rectangular shape and are spaced laterally in a line.

Claim 4

In a recirculating aquarium water biochemical filtration system comprising a housing having at least one sidewall, an inlet for receiving water from the aquarium, and an outlet for directing treated water to the aquarium, the improvement comprising a biochemical drip board for receiving water from said inlet and being formed of a flat board having a plurality of short posts extending down from the bottom of said board, at least one hanger provided at one end of said board, said hanger being connectible to said at least one sidewall, and a plurality of holes at the other end of said board, each of said short posts respectively having a very small center through hole, said hole having active nitrate bacteria attached thereto, said hole defining capillary means for slowing down the speed of water flowing therethrough, for increasing oxygen contained in the water, and for cultivating said active nitrate bacteria therein in a large number so that organic matters in the water are disintegrated into ammonia and nitrogen, consequently effectively preventing said water from worsening.

Claim 5

In a recirculating aquarium water biochemical filtration system comprising a housing having at least one sidewall, an inlet for receiving water from the aquarium, and an outlet for directing treated water to the aquarium, the improvement comprising a biochemical drip board for receiving water from said inlet and being formed of a flat board having a plurality of short posts extending down from the bottom of said board, at least one hanger provided at one end of said board, said hanger being connectible to said at least one sidewall, and a plurality of holes at the other end of said board, each of said short posts respectively having a very small center through hole, said hole having active nitrate bacteria attached thereto, said hole defining capillary means for slowing down the speed of water flowing therethrough, for increasing oxygen contained in the water, and for cultivating said active nitrate bacteria therein in a large number so that organic matters in the water are disintegrated into ammonia and nitrogen, consequently effectively preventing said water from worsening.

Claim 6

The system of claim 3, wherein the plurality of holes at the other end of the board opposite the hangers have a rectangular shape and are spaced laterally in a line.
