8. Use the conductivity meter to test for total solids and plot in a logbook. If your Molybdenum levels drop your conductivity should drop also. This would indicate a loss of water from the

Closed Loop System. If your Molybdenum levels stay constant without having to add treatment to the Closed Loop System, and your conductivity increases you may have air in the system causing iron oxide corrosion. If this is the case, you will see your iron levels increase also. You need to check your air vents for proper operation and remove any trapped air from the piping system and check for bacteria levels.

9. Check the total conductivity of the system with a conductivity meter. Record results in a logbook and typewritten report.
