How old is the tank?

Need some critters to stir it up! Copapods can help some... Is your tank old enough for a goby? What size is it?

You are still experiencing some of the "new tank uglies" that will continue for awhile until your tank matures. My solution for the exact same looking algae was to turn up powerheads full blast, squirt the sand with a "turkey baster" or one of these (below), let the powerheads run for 30 minutes or so, change filter socks, repeat at least twice a week; and adjust water changes as needed.

That's what Dino's looked like in my tank.

Sorry I thought your tank was older. No worries, just good husbandry until the tank is mature and once you have a well established sand bed then you can look into things that will keep it clean. But until then do what Big G said. Patience and some deep cleaning go a long way

Add a lawnmower blenny

Add a lawnmower blenny

I'm not sure there is enough food available for a blenny in this tank just yet.
