Boyu Submersible Filter[SP Series][Flow - 1400L/h, Model - SP2500-B]

FEATURE This product includes both a diving pump and a biochemical filter. The pump body is crafted from die-cast ABS engineering plastic, ensuring it is resistant to shock and corrosion. The pump shaft, made from stainless steel, is suitable for both freshwater and saltwater environments. The motor is securely sealed within the body using resin, providing excellent waterproof capabilities and high isolation strength, along with a heat protector for enhanced safety and reliability. Its multifunctional design serves various purposes, including pumping, oxygenation, filtration, and UV sterilization (note that the 4-in-1 feature does not apply to the SP-B and SP-C series as they lack UV light). Featuring a portable assembly design, the filter can be effortlessly set up with 1 to 2 filter cylinders, utilizing specialized biochemical filter cotton. This setup is ideal for nurturing beneficial nitrobacteria and maintaining clean water.
