BLH 401 hang on filter 4W

The BLH-401 Hang-On Filter 4W is a reliable and space-saving filtration system specially designed for small aquariums, nano tanks, and fish bowls. Its hang-on-back (HOB) design keeps the filter outside the tank, saving internal space while delivering efficient multi-stage filtration.

Powered by a low-energy 4W motor, the filter ensures strong water circulation with a flow rate of approximately 250 liters per hour, helping maintain clean and healthy water conditions for your fish. It effectively removes dirt, leftover food, fish waste, and floating particles, keeping the aquarium crystal clear.

The integrated surface skimmer eliminates oil film and debris from the water surface, improving oxygen exchange and supporting fish health. The gentle waterfall output not only enhances aeration but also creates a visually appealing effect in your aquarium.

Designed for convenience, the BLH-401 operates quietly and features an adjustable flow control, allowing you to customize water movement according to your tank size and fish type. Its compact ABS body is durable, lightweight, and easy to install and maintain.

This filter supports multi-stage filtration (mechanical, biological, and chemical), ensuring complete purification of aquarium water and reducing the need for frequent water changes. It is ideal for betta fish, guppies, shrimp tanks, and other small aquatic setups.
