Hi, its another light question, but i was wondering it there is a big difference between the 12k and 20k with growing corals ( zoas, shrooms, rbta, ricordia, no hards) becasue i like the look of the 20k but i dont want to lose the growing power that the 12k has so if you could help that would great thanks btw they are 250watt
 
Do a little searching here and on Google (there is a Google based Reef Central search engine that always works on the homepage ) and you should find that values closer to 10k give better growth while values closer to 20k yield better coloration.

Many people have settled on a 14k variety to get a happy compromise of both growth and coloration, although coloration is subjective and while you may like the color of a specific bulb, someone else may not.

You should also be able to find a comaprison of the coloration between different bulbs.

No problem! Looks like Reef Central was up to its old tricks as my reply was a double post as well!

Good luck finding the right light!
