SunSun HW-603B External Canister Filter 400L/H for Aquariums up to 150L

The SunSun HW-603B is a compact external canister filter with an integrated 400 L/h pump, designed for freshwater and marine aquariums. It provides efficient mechanical filtration while offering the flexibility to be used either as a standalone external filter or as a pre-filter supporting a larger canister filter.

With a 2.7-litre filter chamber and three sponge filter inserts, the HW-603B effectively removes suspended debris and coarse particles, helping to maintain clean, healthy aquarium water. When used as a pre-filter, it significantly reduces the amount of dirt reaching the main filter, extending maintenance intervals and improving overall filtration efficiency.

The filter includes a 6W circulation pump, inlet and outlet valves for convenient flow control and maintenance, and complete installation accessories, including hoses, inlet and outlet pipes, and a spray bar for improved water circulation and oxygenation.

Its compact design makes it ideal for aquariums where an external filter is preferred without requiring a large amount of cabinet space.
