Boyu Submersible Filter[SP Series][Flow - 700L/h, Model - SP1800-A]

FEATURE This item includes a diving pump along with a biochemical filter. The body of the pump is crafted from diecast ABS engineering plastic, making it resistant to both shock and rust. Its pump shaft, made from stainless steel, is suitable for use in both freshwater and seawater environments. The motor is securely enclosed within the body using resin. Designed for excellent waterproof capability and high isolation strength, it features a heat protector for added safety and reliability. Its multifunctional design allows for a variety of uses in one device—pumping, oxygenation, filtration, and UV sterilization (note that the SP-B and SP-C series do not include UV light). With a user-friendly assembly structure, the filter can be conveniently set up with one or two filter cylinders, utilizing specialized biochemical filter cotton. This makes it ideal for nurturing beneficial nitrobacteria and maintaining clean water.
