Reeflux 14k replacement help

[mano1192]

I have a Reeflux 14k running off a Coralvue 250w electronic ballast. The color is nice and crisp blue, but I am not getting the growth out of my SPS I would like. I have heard the 20k XM's are getting great growth, I was thinking about them, but would like to hear some suggestions ,if u have any growth pics that would be great also.

Thanks,
Steve
