ABSTRACT:
An improved pollutant tray structure for an aquarium, which comprises a pollutant tray and a filter cover; the pollutant tray includes a given number of such trays connected together in series; the pollutant tray and the water passage are molded integrally into one piece; the water passage is mounted with a water pipe connector having a built-in removable lamina; a water pipe is used for connecting to a water pump. Both sides of the water passage are furnished with a plurality of water channels respectively; each water channel includes three sloping surfaces to be concentrated to a water-intake hole in communication with the water passage; when the water pump sucks water from the water passage, such suction force will be distributed to the various water-intake holes to suck the decomposed waste substance fallen in a space between the water passage and the water channels.
