So I thought I just had a little diatom bloom on one rock, but it absolutely exploded while I was at work today. These pictures may make ID difficult, but it is dark brown (not as red to the naked eye as it appears in the pics). It is not stringy and seems almost like a really thick covering of spider web. I'm going to do my weekly WC tonight and see how much I can siphon out, but if anyone can supply a positive ID I would appreciate it. I just know enough to be freaked out by it (dino, cyano, film algae, diatoms?)
