Yeah...I read up on the old ones with the halogens. I pulled the trigger when they came out with the LED models. I supplement the lighting with a Marineland LED fixture that I put to the front of the cover. Surprisingly enough, I've had no problems with the corals. I do have a couple of Goniopora that I had gotten from friends that seem to be doing ok, but am waiting for the demise to occur, lol. Other than that I have the typical fare, torch, frogspawn, zoas, candy canes and some various mushrooms. I did have a banggai cardinal in there, but for some reason the thing never ate and wasted away. I've since settled on a pair of clowns and a firefish goby. So far so good, although the urge to add more seems rather overwhelming at times.
