The SunSun HW-603B external filter is a practical choice for smaller aquariums. Water flows vertically through five filtration zones that support both mechanical and biological filtration. The space above the filter media is intended for the growth of nitrifying bacteria, which help maintain biological balance in the aquarium.
The filtration system uses a blue sponge to capture sediment, a yellow sponge for fine particles, a black sponge to filter colloidal impurities, and white non-woven fabric to remove residual water discoloration. The external JP-450G pump provides a maximum flow rate of up to 400 l/h and ensures stable water circulation.
