They removed phosphates from laundry detergent back in the 70’s I think. Then in early 2010, phosphates were removed from dish washing soap. The reason being is they cause algae blooms and low oxygen (eutrophication) in lakes.
You can still buy commercial dishwashing detergent on line with phosphates.
You can also by TSP at home improvement stores and hardware stores and add a little yourself.
I know that is true because I constantly have to put an additive in my pool water that makes the phosphates settle to the bottom. If fogger truck for the city comes around spraying for mosquitoes, it only takes about two days before my pool turns green if I don't treat the pool for phosphate.
