I had to pay extra for that!
Actually the tank is doing well. The HA is dying off and the rocks are getting their color back. WHen you take a look at it as a whole it really is progressing into a nice reef system. I seem to have more hermits than I put in as well, so maybe some came in on the rock.
Strange thing is that although they came in with red, orange, yellow, purple & other colors of coraline algae, the majority of the rock is now purple. I am not sure why but it could be because of the type of lights I am using, or perhaps that I have dosed the tank a few times with Purple Up. I figured that was just to encourage any coraline algae grow but perhaps it's just for purple?
