I have well water. After my water goes through my RODI, I have 0 TDS. I tested my water from the container (Brute trash can) that holds my filtered water for phosphates with a hanna checker. I am getting .03 ppm of phosphates. Should I be concerned?
Also tested for nitrates with salifert, had 0ppm.
