Bio-Mat is a slimy black substance that sits above a layer in the soil called Hard Pan
Bio-Mat is a waste product of Anaerobic Bacteria (bacteria that lives without oxygen). A septic system starts out as an Aerobic Bacteria-based system, where the bacteria lives with oxygen. Once Hard Pan forms, the oxygen is depleted over time, causing Aerobic Bacteria to die off and allow for Anaerobic Bacteria to take over.
Bio-Scrub removes organic material and Bio-Mat instantly, allowing for a healthy aerobic atmosphere for bacteria in septic systems.
