E450 cutter is a commercial phosphate binder. You could use AmesPhos or Butcher & Packer #414. The B&P Carrot binder would probably also work, as would other common binders. I don't know if the ratios translate directly, so I would go with rates for the binder you decide to use.
Thank you Muhkuhmuh for posting the translation!!! Saving this one to try soon.
