The filtration systems of aquariums are characterized by their variety for a variety of animals but not for their high density culture. Keeping birds and marine mammals damages water quality heavily. Ideas and measures are devised for the facilities to remove feathers and fur. Ratio of daily filtration water volume (or dimensions of filter bed) to water volume of rearing tanks is used as an index for filtration of rearing water in aquariums, but a standard has not been established. The index varied considerably in different researches on the equipment of water filtration for aquariums in Japan, thus a standard value of the index seems difficult to be decided.
