To get the gunk off the pieces of slate literally all I do is brush them off with a (clean, treated) tooth brush every other time I change their water.

The only problem with doing that is you will wash away your good bacteria.

He's not disturbing the bacteria. He's just brushing off the gunk so it can get sucked up by the siphon.

That 'gunk' contains the nitrifying bacteria.
