This test kit measures from <.05 - 3 mg/L. When I test the color is coming a brighter yellow than is on the chart but indication 0. The directions indicate that if higher a precipitation would form with the appearnace of tiny black or blue speckles, which didn't happen. I tried 50% distilled & 50% tank water with the same results. Although 0 would no doubt be best, I doubt it as I have no way of dealing with phosphates except the skimmer and weekly water changes and this yellow color is off the charts! Any similiar experiences?
