Forget About It For Boats will not and cannot harm the environment because it consists of 14 to 17 naturally occurring probiotic (beneficial) bacteria that is blended and fermented in a 30 day patented process that is OMRI certified and GMO free. The government mandated Safety Data Sheet confirms that it will not cause any harm to the environment, people or property and will not cause a negative reaction when combined with any other material. These beneficial bacteria will be a positive benefit to wherever they are applied. In order to continue to grow these bacteria need to capture the quorum of the environment where they live, limiting a positive large-scale environmental impact like a large lake, river or ocean. They can only help, not harm any environment they are placed in.
