Not familiar with that light but first thing I would do is raise that thing to the level of the halide and cut the intensity. The blues on my radions have never been above 65% and are currently at 50%. Try cutting your blues to 50 whites to whatever looks good and see what happens. The thing you have working against you is that halide. The led will look extremely dim next to the halide. A par meter would really be helpful. The secret with led is to start low intensity and slowly creep them up. Also the higher off the water the better, especially with that shallow frag tank. I'll admit you do have to use "the force" a bit with LED which I think is their biggest drawback. My advice is worth what you paid for it, but I bet if you make those adjustments and be patient you'll see "the light"
