Title:
WATER TANK APPARATUS FOR ADMIRING
Document Type and Number:
Japanese Patent JP2624620
Kind Code:
B2
Abstract:
PURPOSE: To provide preferable environment to fishes and waterweed plants without giving unpleasant feeling to observers by mixing a carbon dioxide- housing body with an additive having deodorizing or water quality-improving effect.
CONSTITUTION: A sucking disk 11 is absorbed to the side of a water tank 1 so as to sink a whole diffusing device 12 in water A of the water tank 1. By carrying out rotation operation of a control valve 8 in this state, a water-soluble substance 14 attached to the outer circumference of a natural zeolite 15 is gradually scattered together with carbon dioxide B in a gas cylinder and carbon dioxide B containing a main component of the water soluble substance 14 is fed out from a connecting port 7 through a feeding pipe 9 into the diffusing device 12. Then, the carbon dioxide is formed into fine bubbles when the carbon dioxide is passed through the porous film. A waterweed plant 4 in the water tank adsorbs carbon dioxide B.
