What t5 kit are you using? Thinking about supplimenting my radion with 4 t5s as well. great looking tank!
I'm using the sunlight supply 24" t-5's all in one fixtures I got from aquacave.
Ok so here's some coral growth pictures so you can see what kind of results this lighting setup is producing..
First pictures were taken on Dec. 10th so about 3 months
I feel I could be getting better colors but time will tell.
