Hey guys I was hoping for a little advice or experience. I purchased a couple of Radions, about six months ago, and I decided to set up the traditional reef aquarium template . I started out at 30% intensity, two months ago and I'm up to 45% . I have a par meter I'm only getting about 250 where my corals are (SPS at 6 inches below the surface my lights are about 18 inches above the surface. Over the last month, I have gotten a huge green and brow algae outbreak. Also a lot of diatoms on the sandbed. I had 2 ebay leds, at white 30% and actinic 100%, and 2 T5 bulbs running before the radions. My parameters are PH 8.3, Mag 1400, Calcium 500, KH 9, Nitrates .5, and phosphate . 2 (very low on both). I have 1 tang, put in 10 turbo snails and 2 long spine urchins, but they can't keep up. I have been told it's because I am ramping up my Leds. I am increasing intensity 5 % a week, and trying to reach 400 par at my SPS, and 100 at bottom of my 92 bowfront, 26 inch deep tank, for my LPS, acans, chalices. I just started a 3 day blackout. I had dinoflaggelitis about 9 months ago and learned that it will get rid of most of the algae, but not hurt corals. ANY SUGGESTIONS OR INPUT MUCH APPRECIATED !
