You can adjust the volume of the stream for each circle. Click open the nametab for the Follow circle from the left top side of the home (stream) page under your small profile pic and name. Then check the slider top right.
If you want to mute the circle, slide all the way to the left.
You can still visit the circle and see their posts but this way they don't swamp your main stream. Same goes for all circles, there are 4 levels of adjustment.
