I think you'll find the tank very blue with the actinics, whether it is too blue...your personal taste will have to dictate that. If you go to http://www.cnidarianreef.com/lamps.cfm
and look at the CV 20K pics with actinics, it will give you an idea
of how blue it will be after the actinics have burned in, but it needs to be noted those bulbs are 250W and the actinics are vho
, I am about to upgrade to 250W 20K XM and plan on running my actinics, this may change after burnin if I think it's too blue, but right now that is the plan.
