So my tank has been up and running for about 3 months and I have a brown alge growing on my rocks. I'm pretty sure it's just new tank uglies but I was just wondering how do I get rid of It? Or will I go away on its own in good time? I currently have 2 damsels and a flame angel in the tank along with a few hermit crabs and an assortment of snails. So do I just wait it out or do I need to do something else to It? Thanks guys..
