PROBLEM TO BE SOLVED: To prevent scattering of water by aeration to the inside/outside of a water tank, thus solving such problems that aeration by a pump is required for raising aquarium fish and the like in a water tank, however, fine bubbles generated by the aeration are continuously split on the water surface, and instruments such as a glass lid and an upper filter are wetted and contaminated by scattered fine water droplets, and, in a sea water tank, scattered sea water stuck to instruments results in deposition of crystallized salt to cause so-called salt sagging, seeping of salt water outside the water tank.SOLUTION: A bubble receiving diffuser panel body 1 in a floater type anti-bubbling device that is installed in a water tank near a water surface in a floating state, receives rising air bubbles from an air stone suspended from a part immediately beneath the anti-bubbling device or an underwater filter disposed immediately beneath the anti-bubbling device to guide the air bubbles to an anti-bubbling cowl 2. This configuration can effectively remove bubbles in both of sea water and fresh water while making it less susceptible to the fineness and an amount of air bubbles and prevent undesirable scattering of water droplet into the water tank. |
