I'm thinking maybe there's crap in my rock. I shut my system down last winter for a while because I was out of town working so much. I just shut the lighting at temp off and kept circulation. If I cut back on lighting am I going to have issues with my sps?

Your sps should be fine, just cut down a couple hours.
