BioTube 1000 25lt Filter Media

Spoke design biological filter media with internal and external fins and surface area of 1000m_/m_.

The Biotube is designed to provide a large protected surface area for the biofilm and optimal conditions for the bacteria culture when the media is suspended in water.

ItÕs durable, rugged and highly efficient biological media suitable for all aquatic systems.

Its innovative design creates a high percentage of protected surface area for microorganisms to adhere. In turn, this increases the overall biomass concentration and can reduce the tank volume required for wastewater treatment. Large openings allow for the wastewater to freely pass through the media which helps maintain a healthy and thin biofilm.
