SPS bleaching, ATI Test Results

[jayare]

Hello all,
Over the past month I've had a major setback as many of my SPS have started to bleach out. I haven't figured out the issue, attached are my results from my ATI test, anything jump out?

Nitrates and phosphates are too low. Try to either dose them, add more fish or increase your feedings.

Thanks, Lazy suggested the same. I guess I backed down on feeding a bit because I’m getting a green slime algae on the sand bed, etc.

If you start to see cyano (green/red slime algae) nip it in but with chemiclean because it can steal nutrients in system as well.
