ABSTRACT:
The present invention relates to an improved leak-proof device for a bubbling port of an aquarium comprising a water tank, a base cover and a base disc, the water tank having a bubbling port on the bottom, and an exhaust outlet setting with a check valve. The base cover has an integrally molded communication connector, and on top of the connector, a check valve. The base disc has an air pump with a connected conduit. With the assembly of these members, air produced from the air pump may enter water tank for bubbling, and because of the check valve and related devices on the water tank and base cover, the bubbling port on the base, of the water tank has double leak-proof effect.
