and the million dollars question:
what kind of leds are you using?

A combination of different brands (Cree and Semi LED) and colors:
p.s. there's a typo in this sheet, it's 405nm violet not 503nm, 503 is cyan.
For more info you can always take a look at my tank thread:

Yep, LEDs work well. I stuck a bunch of brown acro frags under LEDs and already half of them are colouring up. Different colours too. A nice green tip with orange polyps, and a purple tip with green polyps, just for starters
Exactly, I've got this brown piece of efflo frag from LFS some 3 weeks ago:

Right now it looks like this - it's shown some improvement on coloration, hopefully in another few months time it'll turn into a real beauty!

nice shots Acrotrdco !
same experience here with 3 months of leds (reefrepublic )
all my corals have colored-up and growth is great
tenuis encrusting and started to grow for about a month....

Great colors and pictures, but as has been pointed out several times before both the yellow and pink "catspaw" are seriatopora sp.

very nice, I'm hoping if I luck out the maxspect g3 will be out when it's time to replace my current halide/t5 bulbs. Only bummer is I won't be able to get away with one fixture on my tank as it's 36x24x18

Beautiful shots! Very encouraging for keeping sps under LEDs.
I understand you use a small glass aquarium to take the top view shot. Were you using free-hand and no stand to do that top view shot? Did you turn off any pumps at all?
By the way, the tutorial of taking tank photo you gave me a while ago, did help me a lot. I am still trying hard, thanks:dance:
Two of your shots were taken at almost the same time -- the snail still there.

Thanks - I use my left hand to hold the aquarium in place and take the photo with my other hand. That's why I needed to use auto-focus and VR, it's pretty "challenging" to say the least.
And yeah I took the bottom 2 shots almost the same time, the snail was still munching algae around and I didn't want to bother it
Thanks!
Since I'm using NPBP, I've noticed that the PE of all my SPS's are very noticable almost 24 hours a day so I'm pretty sure they're getting a constant stream of bacterias to feed on, therefore I only feed them with Reefpearls about once a day.
In fact, one piece of my leather coral, which was nothing but a small piece of tissue left behind under a liverock when I frag a larger piece, now grow to the size of a dime, it's got absolutely ZERO light because it's growing under a live rock, but it's still growing steadily so I'm sure it's got something to eat, most likely the bacteria in the water column.

If I may... I'm am seriously thinking about switching to LED's. I don't know much about them (just what I've read in various posts). I read it everywhere and there's no doubt that LED's have been proven to grow SPS. My question would be: I know the actual LED will last a long time illuminating the tank but realistically, how long will they effectively grow SPS before the color shifts? What are the claims so far? A couple years? A couple decades?
And when the LED's are determined to have a better effect growing algae than growing coral, how do you replace the fixtures?
Thanks

I don't know the answer to all your questions but I do know that it costs $200/module for the AI units if you ever need to replace ALL of the LEDs them.
I know maxspect sp? users have the ability to replace individual LEDs. CREEs being 10 each and semi's being 5 each.
Hopefully they last at least 3-4 years and someones whos owned them for 3-4 years now can chime in.
CREE states that we'd have up to 50,000 hours of usable light. Do LEDs shift in color after awhile? I really don't know. To be safe I cut the amount of hours of usable light in half. assuming everyone uses a 10 hour photoperiod for 365 days a year, math comes out to be 6.8 years.
