Nice to meet you! Well, it depends on a number of factors. One of those is the depth of the tank. The biggest though is what you want to have. I would not suggest getting compact flouescent for any reef. If you want
soft corals you will be okay with say 1 96watt actintic and 1 96watt daylight. Preferably VHO. Although this is still on the low end as far as I know (I'm by no means the expert

) If you want to keep
stony corals or most anemones you will need twice this or 1 175watt halide with 1 actintic if it is 18 in. If it is 24 in I would suggest a 250 watt(this is coming from someone with a 24 in deep tank with 175 watt halides! BUt if I could do it again i would get 250s) Whatevery you decide, make sure you're satisfied with it, or you will end up redoing it, like I'm about to. Good luck! Keep us posted!
