It's a 2 bulb hood. For the 29g: a 24w 10,000k Daylight T5HO and a 24w 460 nm Actinic T5HO lamp. OTOH, was given yesterday; 55g and a 30 long. Also yesterday, went to the lfs and got salt, sand and put an order for a skimmer, I think it's a CPR something or other. And a 4 bulb hood. Will think about LED's after Wonton (hint-hint) writes her article on how she did it. CB
