Hi Przemek! I have a couple questions on configuration of my Hyperion S lamp on my tank. I am "trying" to create a mixed reef with some SPS on top, with the rest soft and LPS. MY tank dimensions are unusual, with about a 30"-31" depth, 34" left to right, and about 12" from front to back. The lamp HAS to be 6" from water line. With light mounted there, the SPS is about 12"-14" from the bottom of the lamp. I have a Hyperion S 2 x 145W lamp. I am running basic mode at 60% with all colors at 100% except red at 20%, amber at 20%, and total lamp power at 60%. At these settings, I'm seeing color fading, polyp retraction, and eventual STN in ALL SPS put on top of reef (including montis, acros, seriatop, etc). I bought an Apogee PAR meter because I became so frustrated. At 40% total power, I'm seeing PAR readings at top of reef of 200-250, and perhaps 50-75 at bottom. At 40% total power, I was getting Par Readings at top of reef of only 100'ish and 25-50 on bottom. This is what prompted me to turn up the lamp power to 60%. Any ideas to improve my situation? Should I turn red down to 10%, perhaps keep amber at 20% (or put it at 30%). Should I turn down UV to, say, 40%? My photoperiod is 10 total hours, but with a 2 hour ramp up and 2 hour ramp down. Perhaps I should change this to 9 hours, with 1 hour ramp up/down? Overall, I'm perplexed, and your input would be much appreciated! Thanks!
