Xanium X2's

[Delphinus]

I want to second Troy's thoughts ...

Don't make it too hard on yourself! Go with whatever floats your boat. I think the best thing to do is, try something for a year or six months, and decide how you like it. If you like it, continue; if you don't, then try something else. Don't worry if it's "99% right for you" or "98% right for you." I think you'll need to experiment around a little in order to find the solution you find best.

The hype surrounding the Xanium bulbs does make them sound promising, but in a few months time we'll have a pretty good idea of what people think of them... So I guess it depends if you want to take the risk of being on leading edge of the evaluation process, or step back a bit and let something prove itself in the field first.

I do hear promising results with people who mix bulbs. Anthony Calfo's book on coral propagation describes what he thinks as a promising solution and it seems to be a mixture of 20kK's with 10kK's or 6.5kK's. I've heard people on RC trying this as well and liking the results. So Steve you may be onto something with your idea of mixing the bulbs like that....
