TankTechsRx is committed to Help Not Harm. We will not offer any products that could harm the environment in any way. TankTechsRx for Septic Systems is made from a blend of 14 to 17 naturally occurring probiotic bacteria strains that are not modified in any way. Individually or as a group, they have never been known to do any harm. Using a patented fermentation process that takes about 30 days under special conditions, the bacteria are combined in a way that assists them in quorum sensing so they will outcompete all the harmful bacteria that may be present. These probiotic bacteria do NOT kill off the other bacteria but instead outcompete them for the food source. The probiotic bacteria blend controls the environment and maintains a healthy balance. Everything in it is safe for the environment as confirmed in the government required SDS records. Even the food source is non-gmo and it is OMRI approved. The question is since it is growing and multiplying, what would stop it? First it needs a food source. Once it runs out of food, it will go dormant and eventually die. Second, it requires a closed system to capture the quorum. A system of moving water or a system where the probiotic bacteria could not mathematically outnumber its surroundings will prevent it from capturing the quorum and die also. It would actually be a benefit to the environment like the ocean or a large lake if it could capture it, but to the best of our understanding, it is not possible.
