I posted this in another "black box" thread recently:
"I have to say I was skeptical at first about buying my Mars Aquas. I did research about them for over a year before I pulled the trigger, mostly driven by not wanting to spend $200+ on T5 ATI bulbs every 8 months! Over the years I must have spent a fortune on T5 bulbs!
Me and my corals are happy I bought them. At first I got as much or more growth with them, as opposed to the T5's. I did mod them by replacing some diodes to mimic the SB reeflights layout and since I've seen a explosive growth spurt, improved color and excellent polyp extension. And no more $200+ out of pocket every 8 months!
Now if you want to buy the "high end" led fixtures out there ponder this....... I spent $269 on three 165w Mars Aquas and shipped free. Awesome right out of the box. Granted it only has a white and blue channels that are independently dimmable. No Wifi, no timers.......gimmicks.
Now one "high end" fixture costs upwards to $800. One fixture! To cover my tank I need three. That's $2400!
(3)$2400-(3)$269=$2131 saved.
Now $2400/$269 =8.9 (almost 9)
I could buy 24 Mars Aquas units for the cost of 3 "high end" led fixtures!
24! Insane!"
