Hi all. I have a question regarding my 16 Nano bowfront Reef tank. I have a 175 Metal Halide Iwasaki 14K bulb over the tank. The bulb is about 8 months old and will need to be replaced soon, but I was thinking about modifying the pendant altogether. 1st Question: Should I stick with 14-15K bulbs and supplement with actinics or should I go with a 10K and supplement with actinics? 2nd Question: I am modifying the fixture to hold 6 18", 18W T5 HO bulbs. Should I go with 420 or 460 nm actinics? I have read other forums and there seems to be a lot of debate. Does 460 or 420 produce better coloration? Better growth? Should I use a combination?
Lighting?

That seems like a lot of lighting for a 16 gallon tank.
Personally I use only T5HO. Much of combos and colors etc. are personal preference. I like to have 50/50 lighting with 10K because I like the way it looks to my eye. I don't use LED or metal halide because I don't like the shimmer effect.
