You may WANT to stir it up MORE. Deliberately MAKE A MESS.
Then clean it up, knowing you are removing materials that could cloud the water later. For example when you are moving a plant.
I've this in more than one tank, in effect, rinsing the substrate in the tank.
Yes, eventually most of these materials will be incorporated in the bio film or in some other way locked up so they do not cloud the water, but I like removing these things during set up so there is less for the tank's microorganisms to have to deal with.
