Dear Michael, If you mix ...

Dear Michael,
If you mix the different UC and nominal effective size of the different sands, then you will obtain a different UC and a different nominal effective size for the mixed sand.
If you want have a multilayer filter, and you can use antracite, then I recommend you use different densities media as sand and antracite with different size. The you can obtain different layers with different CU and different nominal effective size, and I think a better filtration system.
