SunSun HW-303B External Canister Filter 1400L/H with Built-In 9W UV Steriliser for Aquariums 200–400L

The SunSun HW-303B is a powerful external canister filter with a built-in 9W UV-C steriliser, designed for freshwater and marine aquariums from 200 to 400 litres. Combining efficient mechanical, biological, and chemical filtration with UV sterilisation, it helps maintain crystal-clear water while reducing algae, harmful bacteria, and parasites.

Water is drawn into the canister through the intake pipe, passes through multiple layers of filter media, and is returned to the aquarium after thorough filtration. The large canister design provides significantly more space for filter media than internal filters, delivering superior filtration performance without taking up valuable aquarium space.

The integrated 9W UV-C steriliser helps eliminate free-floating algae responsible for green water, while also reducing bacteria and other harmful microorganisms. This improves water clarity and supports a healthier environment for fish and aquatic plants.

The HW-303B is equipped with a self-priming system for quick startup, making installation and maintenance simple even for beginner aquarists. Its external design also allows servicing without disturbing the aquarium’s inhabitants.
