Lighting Question
 

So here's my question, On my new tank which is 25" deep, I have decided to go with 400w ballasts and lighting. My question is what rating should the bulbs have for output. 20000K or 14000k? I will not be putting in a lot of sps but will be trying a few when tank is set up.
Thanks in advance for all advise.:biggrin:

Still need some help here please.:biggrin:

if you want your colours to pop go with the 20k. the light coloring will be quite blue aswell.
if you want a faster growth from your coral go for the 14k. this range will be a little more white

I like the white brighter look myself so i went with 14k the 20k has a much more blue look to it ..When i had 20k bulbs my sps didnt really grow to much at all even as close to the top i could put them nothing just stayed alive ..changed to 14k and wow what a difference with the color and growth i have sps in the mid level growing good now

400W on a 25" tall tank seems like overkill if you don't plan to be SPS dominant. That's a lot of power and a lot of heat for no real benefit. 250W would be plenty IMO, and you could go with the 14K.

Thanks for the replies, I have decided to go with 250w instead of 400w and with the 14k bulbs.
