PURPOSE:To reduce load of filtration outside of a live fish tank and to effectively clean the live fish tank in spite of simple structure by previously filtering water in the live fish tank, partially foaming water and removing foams. CONSTITUTION:Water in a live fish tank 10 is filtered with a filter medium 38 supported between a peripheral wall of an external casing 34 of a foam separating device 30 and an outer peripheral wall of an internal chamber 32 is sent to the internal chamber 32, soluble protein, etc., in suspension are foamed in space A by a foam generating device 48 and foams are removed from the top part 50. Then suspension is sucked through a conduit 12 by a pump 14, an organism filtering tank 16 laid outside of the live fish tank 10 and subjected to organism filtering treatment. |
