Yeah, I just started mine about a week ago. Doesn't actually seem as tough as everyone on here made it out to be but right now my light is right on the tank because no place on the face of the earth seems to have the mounting brackets in stock. I was really worried about it getting to hot but I had to keep turning up the heater to get it to the right temp anyways. Only complaint is that arranging rockwork sucks because of how much water your hands displaces and the small amount of space. Right now all I have in are green fuzzy grass mushrooms? This is my first attempt at a reef so I guess I will see how it goes. I don't have a sump or skimmer on it though, it's a 2.5 and I would feel stupid with that much equipment next to it. I'm anal about water changes anyways. Good luck with yours!!
