Yep. The turbos were definitely noticed when I added mine. I hardly recognize the stuff now, since I've tried to ensure there are no dead spots in the tank for poop to settle and be noticed. Everyonce in a while I'll brush near the rocks to stir up some that settles there and have it go to overflow and filter. Or siphon the rocks as Fishfreek said. I usually don't bother it at all now. Guess I got used to it now.
