I think you've hit it on the head.
Without consistent rock and sand cleaning I guess her PO4 is built up and now releasing.

OK, now I am confused because I was always told not to disturb your sand because you would just create issues in your tank. I have a conch that has always done a good job. I think that I am having issues now because my R/O was reading 10 on my tds meter and I was dumping in .22 of phosphates every time I was adding fresh water or doing a change. I have that solved now so I am hoping that eventually I will get my phosphates under control again.
