I'm currently using a small horizontal leaf D.E. filter. I use standard grade DE, Hyflo, and Fibracell which is a cellulose product. My procedure is to precoat with a small amount of fibracell which has the smallest pore size then standard and then dose with mainly hyflo and a little standard mixed in. It seems everyone has a different procedure when filtering and most just say "Thats how I was taught" Does anyone have a firm grasp of the mechanics of filtration and why you should use particular Grades of DE for each stage. My reasoning has always been coat from the smallest pore size to the largest to maximize flow. Also does anyone have experience with Perlite or PVPP products.
Any ideas suggestions welcome.
