I had the same issue as the OP with another well known brand (non-live) of very fine same during my set up 6 years ago. It happened despite rinsing it several times. The cure would have been using a larger grade of sand in the first place and spent more time rinsing. I just didn't know any better back then.
I was also given bad advice by my live rock supplier & used a water clarifier. Big mistake. A tacky film appeared ecerwhere but the water stayed cloudy for a long time. Don't use them. The dust eventually is attracted and immobilized on the surface of the rock but it can take some time.
