i have a 12" high tank w 150w mh: noticed some zoas lose color some have better color. the height from zoa to light is about 8".
how high are your light from your zoas? i was just wondering why some people have such strong lighting, 250w or more.
im also thinking what would be the min lighting to keep the best color w minimal wattage.
