There's a couple things you can do.

1. Get some macro algae like chaeto.
2. If you can fit bigger pieces of rock to help finish the nitrogen process. 10lbs plus pieces.
3. Water changes of course.

I believe ideally your nitrate should be around 5ppm. That way your corals have something to feed off of. If you keep your nitrates at 0 constantly, they won't color as much as they should.
