I got rid of the Color adjust shader, created an Add scalar, hooked the Perlin 3D scalar and the output from the Divide scalar into this, then sent that to the last Surface layer Breakup shader input.
Oh, and I also sent the Divide scalar to an input on a Mix scalar with another direct input from the Perlin 3D scalar. This was mixed by a value of 0.9 then sent to the displacement shader function input.
