Knowing Your Underdrain & What Systems They're Suited For.

Have you ever asked yourself or a dealer what kind of sand media filter you should purchase? If so, you've probably wondered about the materials used in the construction of the tanks and the underdrains, and why choose between carbon steel, or stainless steel options.
