Blue Lights???

[txreefer]

I currently have a 40w actentic bulb and a 175w (10,000k) MH on my 75 gal tank. I just got some new corals that look really good under blue light, but I am afraid that my light is not blue enough to see the flouresent colors on my polyps and stag coral. How can I add more blue light with little money? Thanks

Add more 30"/30watt regular flo's to the setup...Go get a cheap shop fixture at the hardware store and strip allthe wiring out.Mount the endcaps directly toyour hood and put the ballast behind or under the tank...This is how all my flo's are done...BTW,That 10k MH is about as blue as they come.
