Over the past several months green coralline algae has started to grow on the glass, rockwork, and substrate. Tank has been running for over two years with pink, purple and burgundy colors growing predominantly. The green coralline is very hard to get of the glass, much harder than the pink/purple type. Is this type of coralline bad, does anyone have any suggestions. I am using 3 250w ushio bulbs, and 2 URI 72" act blue, on a 180 tank. Halides are almost a year old. If the spectrum of the bulbs are shifting would that be causing the growth of the green coralline, and a reduction of the pink/purple variety?
