Thanks,

sounds like cyano bacteria! Common after start of new tank. If you do not want it in there you can use Boyeds Chemi Clean and follow instructions, It will be gone in two days total. If not step up your flow towards the sand bed but not blowing it everywhere.
cut back on lighting periods. It likes light. water changes twice a week. Thats the long route.

Cyanobacteria blooms are common in new tanks. They sometimes disappear on their own. You could siphon some of it out if you want to speed the process. If the problem persists, there are lots of ideas to consider. I have stopped using the chemical approach since the cyanobacteria will return if there's an underlying problem.
