This product is a robust non-pressurized biofilter. Its sensitivity to flow rate variations and power outages is lower than that of a fluidized sand biofilter. When used in a low-head recirculation system, it can be easily submerged to reduce pump pressure. Since air is used for media circulation, the LSB adds oxygen and removes carbon dioxide. Additionally, we offer blue and green options to prevent algae growth and provide a dark environment preferred by Nitrobacter bacteria. Please feel free to contact us if you have any requests. 【Features】 ■ Non-pressurized ■ Can reduce pump pressure ■ Prevents algae growth *For more details, please contact us or download the catalog.

This product is an ideal biological medium at an affordable price. The biofilm transport element is made of high-concentration, 100% virgin polyethylene. It adopts a proven geometric design, ensuring a sufficient area of 7.7m³ for bacteria to settle. Thanks to the buoyancy characteristics of this product, continuous movement within the biological filtration tank using air pumps or air blowers is achieved. This continuous circulation motion causes the old bacterial layer with reduced activity to detach, allowing the medium to be automatically cleaned. 【Features】 ■ Affordable price ■ Made of 100% virgin polyethylene ■ Has buoyancy characteristics *For more details, please contact us or download the catalog.
