Different Spectrum Bulb?

why not run a 20k bulb? I think 20k 150watt bulbs look awesome over these tanks

i purchased 2 of the bulbs you suggested ... we'll see how they look when they get here. its crazy the price of those bulbs .. some listed for 84.00 some places .. i ended up getting 2 out of BC for under 50 bux shipped.

I have a 20k 150w bulb in my light, and love it, wouldn't go back to the 14k. My clam loves it as well, and so do all the corals. Just my 2 cents worth.
