Hi Michael,
I would recommend that if different filtration layers are specified the layers must be classified separately. My perception is also that there is generally a trend away from layering, unless there is a specific requirement for a dual media filter. Depending on the application, I would go for a single layer layer suited for the selected nozzles and then sand must definitely be classified for the specific single media on it's own.
