Adding Argonite Sand to CC

I currently have about 2-3" of fine cc on the bottom of my 180. The cc has about 1 mm grade (each piece is about a mm). It's almost like sand but not quite. Anyway, I was hoping to add another two inch layer of argonite sand on top but have a couple of questions.
Should I be worried about the differently sized granules? I think I read somewhere that mixing granule sizes is a bad thing.
If I just add more of the cc that I already have, will I still get the benefits of a DSB?
Removing the cc I have isn't an option. I'm lazy and it is too expensive to replace.
