Anyone out there have experience with these unit.
I have a 12G nano with a mix of zoas lps and sps. This tank did have 4 x 12" T5 tubes. 3 white 10000k and a blue Actinic. As I had to replace them I found them hard to get and could only get an 18000k replacement white and was unable to get blue actinic tubes. I added a Arcadia Eco-aqua blue actinic LED strip to replace the tubes and have now fitted the aquaray 1000hd tile in place if all the t5s and am still running the Arcadia actinic LED strip.
I started the power rating on 40% and had takenit up to 75%. I have noticed that some Of my zoas, in particular my fire balls which are a blue and orange were releasing some zooxanthellae and have lost some colour, 8-9" from the light also I have just noticed some bleaching on the tips if of two of my acropora, a super blue tenius and a purple tip cereals,and have noticed the polop extension to be poor. these are sitting about 6" Down from the light. I have a planet mars staghorn acro and a hydnophora excessa on the base of my tank which have good polop extension and holding colour fine, however I have some button polop's on the base that have browned slightly.

The 1000hd tile has 10 Cree C-RE Q+ power LED's 7 white 14000K and 3 blue 50000k that run on two channels. Ch1 runs 3 blue and 2 white and ch2 runs 5 white. The controller allows me to ram the LEDs up and down over a period of 4 hours either way. I have the Hd tile on for 11 hours in total 2 hours ram either way giving 7 hours on max power and the Arcadia actinic on from 1 hour before right through to 1 hour after

I have now set my power out put ch 1 to 60% and ch2 to 50% as am sure the corals are suffer from to much light.
 
Would really appreciate some input regarding this and if any opinions on a better light cycle??
