The Vega SFD100 is Sewage and Fat Destroyer that is non-toxic. This product is a blend of bacteria and enzymes. The bacteria are natural, not genetically-engineered. The enzyme concentration is the most powerful on the market. The Vega SFD100 is a proprietary blend of superior aerobic and anaerobic bacteria selected for their ability to degrade organic waste. Within minutes after pouring the bacteria into the affected area, the bacteria begin to eat their way into the waste that has accumulated. This is their natural food. They digest the waste and spread throughout your system, cleaning it completely.
