Detritus is basicly composted poop and left over food and is mud like and collects in corners and where water flow slows down. Are they hard and have to be scrapped off? Because it looks like a small calcifying crustracian or worm. If so there's no way to prevent them althoufh as other things start growing they will be less noticable.

If detritus is settling in your rocks, you might need to increase the flow in the tank.
