That's all NO? wow.. well someone who's generous beyond belief has offered me a ballast that will run 4 48" VHO's so I'm already starting to plan my next 90 reef.
Rich I'm always blown away by how nice your tank looks, and that's all NO.. wow. Here I'm looking at 130 watts of PC on my 15-20 gallon and was wondering if it would be enough. I guess you've answered my question.
