Ok I know that this is a lighting question, but it's much easier to get replies here than on the lighting forum and it is relevant so here goes. I have a 110 watt pc with the dayglo (9200 K or so) that I took off of a freshwater plant tank to supplement the 2 250 watt MHs (10000 Ks) on my 75 gallon reef-in-the-making. This results in a lot of white light in the tank. I am going to be keeping mostly LPS and probably SPS in the future, and I'm wondering if I need actinic lighting to supplement all the white light in there right now. I had considered getting something with a little more blue in the MHs, like the 12000K or 14000K I've seen, but have heard some bad experiences with their durability so I went with the 10000Ks. Would it be wise to get some 55 watt pcs with actinic, or even just normal output fluorescents, or would it be better to try to get an actinic bulb in the power compact strip I already have? Do I really need actinics at all? I have heard that anenomes need actinic light but do not intend to keep any. How important is it to the LPS and SPS? Thanks advance, and sorry bout the length, I know it's a pretty simple question I just feel that detail never hurts.

Replace the two "dayglo" PCs with actinic PCs.
