Just go to the hardware store and buy a box of trisodium phosphate. Mix it into powdered detergent, or add a very small amount (half a teaspoon) to each load. The ban is stupid, as detergents had very low levels of phosphates and are a very small fraction of what goes into the water from agricultural runoff etc.
