well I'm going to be getting a pretty good deal on helios 20K bulbs and the colors they give off are friggin incredible and they arent too blue from what i have seen also the growth is pretty damn good for it being a 20K bulb but im going to order 4 helios and 4 giesemann corals to see what the difference is and how i like them
you also cant forget that alot of the color comes from the ballast they are fired on
Im not too worried about the lumenarc's getting salt creap, im going to have fans setup on the tank and they are going to be about 12-15" off the watermy only concern is that the lights will be blinding other people then if i do it without a canopy, and if i do a canopy i can actually get better light into the tank but hotter temperatures, I'm most likley going to use 4 icecap 80mm fans, i will do two blowing in and 2 blowing out to help circulate the air (2 down low on the canopy to get lower temp air, and two on top to pull the hot air right off the top
