Mars Aqua is not bad lights but too much red and warm white. Lots of wasted energy in spectrums that will not benefit the coral. A little red is needed, but not much. You get enough from the neutral and cool whites. 2 red diodes is more than enough. When folks start looking at PUR instead of PAR they will see why not all black boxes are created equal. I would replace 2 of the red and all the warm white with 14k diodes.I would recommend AURORA Chinese timer led lights,14k whites 2 red 2 violet 2 green full spectrum on channel one,450nm blues on channel two,plus moonlight channel,remote control and built in LCD screen with 3 channels timer,better spectrum and cool features,I am happy with that.
