I agree, if you are going to be getting into coral, then look at T5 lighing and some of the more light intense corals will need a lot of T5 or some metal hialide. I used to have a CF
light fixture and when I upgraded to T5, it was night and day difference. I am now waiting on my T5/MH
light combo to come. It arrives on Tuesday and I am expecting another boost...
If you budget is what it is, and you have to stay with the CF
, then you will be limited on your corals but it is doable.
