I see diatoms not dinos. Diatoms are no big deal, just a little annoying.
Do you see some of the same stuff on the glass if you don't clean it for a few days? If so, does it come off kind of like a dry looking powder that blows away in the current? If so, it's definately diatoms.
Dino's are stringy, slimy, usually have bubbles stuck in the stringy part, and feels like snot to the touch.
Assuming it is diatoms, they are fed by excess silicate. That said, there is always some silicate present, and some diatom growth is totally normal.
Edit, adding;
If the turf in a bucket was working at all, it would have been taking up some of the available nutrients in the water colum. With that nutrient draw, the other algaes in the tank would be slowed some. Take the turf off line and things will have to readjust and it's not surprising that you'd see algea(s) bloom.
