Just because the front of the bottle might say it is reef safe does not mean that it is. That is because these terms are not yet regulated. You still need to look at the back, starting with the active ingredients listing. We have also discovered that just because a product is safe for people does not mean it’s safe in an aquatic ecosystem. Modern science has given us many lab tests to determine the safety of cosmetics, but there are currently few scientific lab tests to see if products are harmful to fish, coral and other aquatic life. We put Stream2Sea products through numerous studies to prove our safety, and believe that our products are the safest on the market for all your water, reef and outdoor activities.
