<P>PROBLEM TO BE SOLVED: To provide a water tank with a planter for improving clarification of water in the water tank by an increase in the amount of dissolved oxygen to lengthen a replacement cycle of the water in the water tank so that only refilling with the water will do to the extent possible. <P>SOLUTION: The water tank with a planter 100 includes a planter 1 for tank farming, a water tank 2 for breeding aquatic animals and plants, and a pump 3 for taking in the water out of the water tank 2 and supplying it into the planter 1, wherein the supplied water is dropped from a drainage hole 4 provided on the bottom plate 11 of the planter 1 into the water tank 2 to cause it to circulate. Bamboo charcoal 6 is used as the green base in the planter 1, and in addition, the drainage hole 4 is formed in a funnel shape including a conic part 41 shrinking in diameter from the upper part to the lower part and a leg 42 having the same diameter from the upper part connected with the lower part of the conic part 41 to the lower part. <P>COPYRIGHT: (C)2011,JPO&INPIT |
