So I have been fighting this

Cyano? since I've gotten back from break. I had been using a Hanna checker which had read phosphates as high as .23. I had gotten it down to .16 on the checker but had my doubts about the tests. I had checked API and it was near zero. I picked up a Lamotte kit and tested it twice today and again zero. My nitrates, nitrites, and ammonia are at zero. I went so far last week as to siphon it all out during a water change and it still came back.
Funny thing is the rocks are clear in the morning just after the lights come on and it grows like mad through out the day. My SPS look like crap and I have lost a few. Any advice?
