0 SeaScapes 14 Report post Posted July 26, 2009 I thought it was algae but boy did it take some chemical and some work. If it wasn't slippery feeling to the touch I would have thought it was stained. But due to the fact that it was slick I am also led to believe that it was some form of algae. Share this post Link to post Share on other sites
