I'm another person who has been endlessly tweaking their light trying to make my corals happy. I have had the light for six months I just can't decide if they are getting too much or too little light. My only SPS is a monticap up at the very top which went from a dark brick red color to a washed out pinkish red and it doesn't grow at all. My zoas have all faded in color & are not spreading. Frogspawn and hammer have gotten paler and now have skeleton showing. Ricordias mostly shriveled up and disappeared.
Crocea clam on the sandbed seems happy, which makes me think there is plenty of light, and yet the zoas look like they are stretching towards the light which makes me think there is not enough light!
Tank is 24" X 24" X 20" deep. Running one Radion. Parameters good, stable & unchanged from when everything did well under MH + T5s.
I am determined to make this light work for me - I know it can, I just think I haven't hit the right settings yet. I get so confused by the massive differences in how long people run these lights, at what intensity and what color spectrum.
Currently I have just given up and put it in Natural mode with a 12 foot depth offset and I have it at 55% intensity and am thinking I should slowly increase it to maybe 60-70% intensity?
I just got LEDs but I did switch from MH to t5s and I noticed my corals paling out. I started feeding more and my colors really turned around. I wonder if the extra intensity of light on the corals caused them to need more nutrietns. It worked for me with t5s.
