I've seen Harvey's tank: Harvey, would you consider to have had excellent growth in your sps' ?
Thanks

Well, I wouldn't say I have super fast growth, but I do have some decent growth. You could always run an AB 10000K on a HQI ballast. It is suppose to burn at ~13000K that way. Nice white color and lots of par!
