Find the ppm of phosphates and nitrates in the water?

There is no easy way to do it. Both of these ytes require lab testing by specific means determined by USEPA. There are home checks (see reference), but normally they do not work well if the water is very clean or very dirty. They are at best semi-quantitative. Some of these can be bought at pool or hot tub stores and maybe some hardware stores.
