Fans are not standard nor are they an option, they simply aren't needed. The hood is designed so that all the heat radiates off the top and not down into the tank. Directly cooling double ended bulbs is a big no no because they don't have an outer shield to protect them.IcantTHINKofONE":2famtauc said:Rich, are fans standard on it?
You are looking at 45 pounds because the ballasts are internal to the unit. Hanging from studs is ideal. If you can't do this, do what I am doing on my new tank. Lag bolt a 1x4 board to the studs in the ceiling and hang the unit from the 1x4. Doesn't look bad when you then paint the board to match the ceiling.thinhvu":1etobs8q said:How heavy is the fixture?

I don't have any direct links off the top of my head. Try the search engine on reefs.org and reefcentral, I know there are alot of threads out there. The search engine is really easy to use.IcantTHINKofONE":3f7ldmxe said:JT, or anyone, do you have a link where I can learn the difference between SE and DE bulbs and their pros/cons?
Marco, nope. The colors all blend together really well. I like to have the actinics on by themselves late at night, at the end of the photoperiod, as I unwind.. corals look really cool.Marcosreef":2voanr5w said:On the 48" 250w w/ 2 PC's, they put the PC's directly in the middle of the fixture. Will this cause a blue section in the center of the tank?
