Also, as far as your actinics, I would personally very highly recommend the actinics. I have my actinics and VHO's on separate ballats, and I accidentally kicked off the actinics yesterday and about got sick... ugly with just the plain light, looked yellow. Its a nice crisp white with the actinics, and a nice blue when the VHOs are off. I run the actinics all the time so that there is a light in the tank at night.
