I can say the same for those 14 k's I bought on ebay. I haven't seen any algae growth in the tank to this point, the zoas are dividing good, the colt coral is increasing its size.. All seems well.

what kind of color is 14k and 20k? Like super white? Can you get those colors in PC, or only MH? The only PCs I've been able to find are 10k.
10k is pretty much as white as you can get. Less than 10k (6500k for example) tend to be more yellow.
14k is bluer and 20k is really blue....these are generally used to stay away from actinic support.

Before I make a final decision I'll probably borrow a few bulbs from other reefers to compare. They are pretty generous about that.
I'd say so sploke.. I just run the 14k MH because I didn't want to buy another light fixture and add to my already overwhelming electrical bill.
I just bought 20K and I love the color. The brand i bought actually isn't "really blue" but gives off a blue/purple hue which I like. I had 15K in before and it was a nasty yellowy white so I bought something away from that, there was not a blue hint to those in the slightest. I'm happy with the 20k I have now.
Keep in mind that you will probably get slower growth with the 20s. Some compensate for that by moving the bulbs closer to the water.
Yea, they are on leg brackets, so only about 5" or so above the water. Without a cover over the tank itself, the temp stays in spot I want it at and steady, both night and day, Thanks for the info about a possible slower growth. I've not come across that. But, I'm okay with that as long as I don't have to walk in and see the god-awful yellow of the crappy other MH bulbs.
What brand of bulbs? 20k is usually pretty blue... i love the color personally, but the color you describe sounds to me like a cheap brand of bulb, same with the 15k... usually the 14-15k are a very nice crisp white/blue color.
