I believe the 'colloids' as referred to are ions which have clustered together 
in solution, with each ion surrounded by or encased in water after the ion 
clusters - particles - are formed.  Example…A bunch of balloons all touching 
each other, each balloon is water and inside that balloon is a pea, in this 
case the pea would be a silver ion.
Ions are in rapid and constant movement in solution {Brownian Motion} hence it 
takes time for the solution to stabilise while ions are colliding with each 
other forming ion clusters - bunches of balloons.

    Just curious, isn't colloidal silver a colloid once it is made?  Why
    does it take 2 days settling?  BTW, it was probably 4-5 hours after
    the Silver Puppy shut down when I added the H2O2.

    

    

    
      Often it will turn cloudy if you add it immediately after brewing.  Most
people wait about 2 days after brewing before adding H2O2.
