Taotronics LEDs and SPS - need advice

A few months ago I bought this taotronics led fixture:<br />

This thing is insanely bright... I was unprepared for the intensity of these LEDs and even at 18" from the water surface and with a glass lid every SPS coral I put in my tank starts to go pale after several days and takes a long time to adjust and start to get their color back. The corals are about 12" from the water surface in a 24" deep 60 gallon cube.<br />
<br />
I do like the fixture and my corals are growing; the colors don't look so good but they are improving given months to do so. I suppose what I am looking for here is a bit of advice as this is my first LED fixture. My photoperiod is 11am blues on, 2pm whites on, 10pm whites off, 11:00pm blues off. I have considered slowly reducing the photoperiod, especially the whites, but I have been slowly adjusting the fixture higher up to this point instead as I personally believe in making changes slowly rather than drastically. I'm a little hesitant to move the fixture any higher because of the LPS that are down near the bottom of the tank.<br />
<br />
Chemically my tank is in great shape, I feed my corals well, the lighting has to be the culprit. <br />

What do you guys think?

 

I assume that they aren't dimmable. For more light savvy members, Is there a way to add a dimmable driver to this unit?

Sorry I couldn't really help, but here is a bump for you.

 

If you can remove some LEDs, and wire meanwells in parellel to handle the forward voltage, then yes, you can make it dim. You need to know how to solder and shrink wrap connections, and also need 700ma quick blow fuses

 

Haven't one of these. looks pretty neat from the picture looks like its not dimmable and your corals are getting too muck light. might need to hang it up some. then bring it back down. you got some picture of your tank?

 

Yup, not dimmable

 

You could also try and decrease the photoperiod or but some egg crate or tinted plastic sheeting to put under your light to decrease the amount of light your corals are receiving. I would decrease the photoperiod when I would change bulbs when I used to run metal halide/T5 bulbs! There are a lot of ways to decrease the amount of light your corals are receiving, just have to be clever about is sometimes.

 

Nope, not dimmable. I do have the technical proficiency with electronics to add a dimmable driver to each set, but I don't really have the time. Not to mention its expensive. Might just as well replace it with something dimmable if I went that route. I may try raising it a little and reducing the photo period by an hour or so in 30 minute increments over a few days. I will observe and take further action when I determine if that makes a difference. If all else fails I will just buy a new fixture.
