Have any of you been keeping them with LED lights?
What differences have you seen?
With the higher par value do you need to place them differently? (higher lower)
And have you noticed faster development?
this one i do not know of quite yet, as you know my frag tank is leds, i have z's and p's in it. so far one of the considerable things i noticed is my 2 polyp rasta is almost 4 polyps now (2 babies about to open) as for the other coral i havent been keeping good track of, its only been going for a month now. my grow out pack is under the LEDS so we'll find out soon enough of they can keep up with the rest!
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.
