The new tank is looking good. I starting looking into lighting that was out there compare to what I currently received when I purchased the new tank.

I currently have 2 * Philips 20w 24 inches which are a blue tint and I have 1 36 Sunglow 30w and 1 36 power glow 30w. I check the ballasts, which are rated for a max of 40w.

When looking at the various web sites they refer to mh, pc, VHO, 10000K, 12000K,

Being new to the saltwater world I am confused when the web sites refer to spectrum instead of the name of the bulb. In the fresh water world it was easy. Just buy a power glow and you were all set.

The question is what can I glow and maintain with my currently lighting situation.

Thanks in Advance,
