I have bubble algae in my reef tank. I bought the tank used and it already had the bubble algae, so I can't comment as to the cause of it. How do I get rid of it though?!?! I bought a couple of emerald crabs about 3 weeks ago and I haven't seen a difference...do I just need a bunch more? I've heard that increasing magnesium helps, but if possible I really want to take care of this as naturally as possible.
Thanks in advance.
