Indeed, Ken is the best. This was my first reef tank and so I knew very little practically when I came into the hobby. I did a whole lot of reading but that only gets you so far. In the beginning, Ken helped fill in many of the blanks for me.
I liked my Phoenix and also swapped out to the ATI Blue+ bulbs. They were good and I ran them for 6+ months but my colors just weren't where I wanted them to be.
Like I said, I'm new to this so it might not have anything to do with the bulbs ultimately but I like to experiment and try new things. This trial is not cheap though as those MH bulbs get pretty expensive pretty quick. I'm also going to trial the Fiji Purple T5 bulb, which I hear improves reds/oranges, etc.
I let you know how the Radium looks once its burned in a bit. I have some very sweet SPS frags coming on Tuesday so I'm excited.
