Yeah but if it was red think of all the extra money you could have to spend on the tank.

Thanks for the replies everyone I really appreciate you taking the time to reply.

One more question though, when you say Sun Argo ballast, is that a name brand? I guess the Radiums have a real blue look to them, if I used the Radiums do I need actinic as well or is it blue enough to minimize the need for the actinic.
