So it's been 2 months since I put a red tabling acro and a unknown blue/white acro in my DIY LED 7.5g cube. I haven't been dosing anything, just water changes at the moment, so the growth rates might have been better with better water quality. Here are the results I've had so far.

Blue/white acro



Red planet tabling acropora



I've also had other coral show growth. My birdsnest has grown to twice the size from when I got it, and my digi has encrusted well onto the plug. The neon green candy canes have split, there are probably twice as many than when I got it. My maxima clam also seems to like the LED's. I've ended up putting a lot of my coral in this tank because the growth rates are far better than in my 55g, which has a 4 bulb t5 tek light with 3 blue plus and a special blue. I will actually be switching out the t5's on the 55g with LED's as soon as possible.

I will update as I get more progress.

    I've also been seeing great growth with my own LED's, particularly a Derasa clam has shown a lot of growth in the month and a half that I've had it. But I've also seen the colors really fade out on a few pieces. The Derasa's colors have come back nicely, as has one acro frag, but everything is is really washed out now. Particularly my almost transparent, but growing like mad, frogspawn.

    I'm not sure yet if it's because they are taking so long to adapt to the LED's, or if it's because of the EcoBak pellets I'm running.

    Some of my acros got a little bleached at first, but they recovered nicely and have good color. They are probably just adapting to the intensity of the LED's, but that's just my opinion.

    The fading in colors could be due to not getting a wide enough spectrum that you need out of your LEDs. There is a big post on nano-reef.com in the lighting forum about this, and people are trying out different color LEDs (like cyan, neutral white, cool blue, regular blue, red, and even uv) in order to bring certain coral colors back. May want to do a site search and check it out, since i'm not sure about the rules about linking on this site.

    I read through that thread when I was setting up the LED's, great thread. I have 1 cyan, 2 neutral white, 2 cool white, and 4 royal blue. Colors seem to be good, the red planet actually looks better than when it was under MH IMO. I'm going to be experimenting with some of the other different color LED's when I light my 55g.
