my personal tank is 4x250w 10k XDE, and i love the color. i do want some actinic supplement, and the light box to hold them is being built currently. At the store, all the tanks are T5. 54w HO. The softies have 2 bulbs, 1 10k and one actinic. The fish have 3 10k and the SPS have 3 10k and 1 actinic. nice bright light, but the tanks are only 10" tall!
