When To Replace The Titanium Electrodes In a Spa System

How to know when to replace the Titanium Electrodes in a spa system.

The titanium electrodes have a black or grey coating on the surface of the plates that face each other.  As long as this coating is intact, the electrodes will work.  If the coating is gone, the plates will have a "silver" appearance and should be replaced. 

Another way to test the electrodes to see if they are still producing oxygen is to test the dissolved oxygen (DO) in the water.  If the ECOsmarte system is working properly the DO should generally be above 6.0.

If you aren't sure, you can send a photo of the electrodes for us to help determine whether they should be replaced.
