I have recently seen this new aquarium led light by ecoxotic. Looks beautiful on display but I have heard many things from different people that have never even own an led light system. I heard that they dont have the brightness to even make the coral grow. They will cost me over 2000 dollars to set up the system in my aquarium but i dont want to blow that money in something that is going to be useless. Has anyone here ever use leds as main lights instead of MH which is what Im running now? ...
