The 50 gal tank I'm buying comes with a 48" PC fixture that has 2 24" bulbs. It's a Custom Sealife SmartLite. I'm worried that this won't be enough light if I want to have any type of reef setup, especially if I want to get an anemone. What do you guys think of this? If it's not enough light, does anyone have a 48" fixture that would meet my light requirements?
