About a week ago, I started to see some brown thin growth on my my rock. I started cycling the tank in January so it is still pretty new. It appears to have a some sort of head on it like a weed. I am not sure if it is an algae. I can't find anything quite like it on algae websites. Unfortunately, it has nearly taken over the tank. My phosphate is 0.02 ppm and my nitrate is as close to zero as I can tell from my Red Sea kit. I have slowly been acclimating my lights for my 8 corals. My corals seem to be fine. I have attached a picture. Any help would be greatly appreciated.
