I know, odd time of year to be asking a question about sunscreen, but we're going to mexico in a few weeks, and we'll be in an area where there's a lot of marine life (a lagoon), and I'll be diving on a reef, so I want to find a sunscreen that's safe for coral and fish. Has anyone found a biodegradable sunscreen that worked well? I want to get it before we leave because it's super expensive down there. Any advice would be great!
Thanks
