Lighting for my reef tank question?

I am setting up 90 gallon reef tank with live rock and corals. I was thinking of going with 4 actinic lights 2x 65 watt 460nm and 2x 65 watt 420nm for my cf lighting system which is my main lighting system 260 watts total. I was told if I do this my live rock and corals with thrive and I will get great looking deep purple coraline algae along with adding typical reef additives. I was going to go with 2×12000k and 2×460nm actinic. Which is better for my live rock, fish, and corals?

i would not use actinics only for the tank, it is true that coral need actinics but they need several different wavelenghts. look at the PAR rating for an actinic bulb. i would go with at least a 150w metal halide with actinic power compacts, they have dual actinics for those 420/460 nm. you have a 25″ deep tank and power compact jsut wont cut it for corals down low, mushrooms would have a difficult time down there.. if you really like the blue look go with 10,000k or 14,000k halide bulbs, there are alos 20,000k but theyre real blue and wont show the corals colors off to well, a 10k or 14k would be as high as i would go. there are retrofit kits or gutting out a clamp halide bulb if you have a hood and a bit of DIY skills. i will add some sites where you can see pics of different lighgting combos, and bulb combos give me a minute to find them
