Im finally ordering a metal halide fixture for my 80gal, it is a dual 250w electric ballast. The guy im buying it from is going to throw in 2 free bulbs.. 10k or 20k. When i went to my LFS they had a 14k that i really liked. My question is if i get 1 20k and 1 10k will I get something inbetween? Will the side of the tank with the 20k be bluer than the side with the 10k or will it blend.
