I had them for 6 months. My green cap/purple rim had the most vivid bright coloring to it as did my tricolor acropora. The purples really popped! I aslo had a couple of orange caps, hydnophora, some orange montipora digitata, staghorn... these all grew great and colored nicely. When I changed over to my MH
the orange monti digi started bleaching as did my orange caps (in spite of a very slow introduction to the MH
lighting) Maybe they needed to be moved down, but they were very colorful under my PC
lighting. I didn't have anything that was all purple or all pink. Those are tougher colorings to grow with just PC
but it gets really tiresome hearing broad brush comments that you can't have any SPS
lighting. That just isn't true based on what I saw in my tank as well as fellow reefers here in NJ.
