## Abstract

A sterilizer for an aquarium includes a pump for sucking water in an aquarium and a filtering member for filtering the water. The pump includes an inlet from which the water in the aquarium is sucked. The filtering member is connected to the underside of the pump and includes an outlet through which the filtered water flows back into the aquarium. Multiple reflectors are connected to the periphery of the filtering member, and a coat is mounted to outside of the filtering member and covers the reflectors. Multiple ultraviolet sterilizer bulbs are located in the filtering member so as to treat the water sucked from the pump. A cotton sleeve is mounted to the pump and located around the inlet to remove debris and grease.

## Claims

### Claim 1

A sterilizer for an aquarium, comprising:
a pump for sucking water in an aquarium, the pump having an inlet so as to suck the water in the aquarium into the pump;
a filtering member connected to an underside of the pump and having an outlet defined radially therein, multiple reflectors connected to a periphery of the filtering member, a coat mounted to outside of the filtering member and covering the reflectors;
multiple ultraviolet sterilizer bulbs located in the filtering member and connected with a power source from an underside of the filtering member to sterilize the water and
a cotton sleeve mounted to the pump and located around the inlet to remove debris and grease.

### Claim 2 (depends on 1)

The sterilizer as claimed in claim 1, wherein the reflectors each are an angled plate or a planar plate.
