I am having a big problem with some green hair algae. Its primarily growing only on the rock I have all my green hairy mushrooms on, but is starting to spread across some of the other corals causing problems. I added a few more emerald crabs and a lawnmower blenny hoping they would take care of it, but they didn't. So now im hoping there is something I can dose the tank with to help get rid of it. I have tried scrubbing and doing a water change but its resistant to everything. I will attach a picture below to show you what im talking about.
