Notes

Phosphates = 0.15

Nitrates = 10

Nitrites = 0

The Curdies multifunction meter (Hach HQd40) could not be calibrated because it required NaCl calibration fluid, and we were unable to change it to KCl, our normal calibration fluid.We borrowed another meter from Colac CCMA, but this meter had a faulty Electrical Conductivity probe, and gave no EC readings.

We tested with both meters, but recorded the Curdies meter results in our report.

The results from both meters are shown in the Data Sheet
