I have a 72" Current Outer Orbit with 3 150 watt 20K halides and 8 (4 rows of 36") t5s. I already replaced the halides but am now replacing the t5s. Someone else had the light before me and their light mix is 1 row 10k, 2 rows fiji pink and 1 row 14k. I got advice to use some 15k ATI special blues, but what can I use for the other rows? I already bought the 15ks. I'm using the light over a mixed reef grow 100 gal rubbermaid tank. The light is about 16" above the water, and coral about 8" below the surface. Thanks.
