Response to Hi John, The Waterway filter does not use any DE so you would just use the cartridge. Most cartridge filters just use the cartridge and no DE. The Regenx filter you had was unique in that it used a cartridge along with DE powder, there are no longer any filters that use both cartridge and DE powder.
