i went from a 180 with 3 400MH to a 50gallon tall with a blue moon aquatics 90w led. the color is different for sure. the corals i have(Zs,Ps,sps,lps) all seem to love the light,and are growing well, as far as growing faster only time will tell. i will note that the led lights will grow hi light corals lower than par meters suggest. by far the best thing is the Glow.
