I have a 2008 Tundra Onzen tub and have now had the Onzen electrodes replaced 3 times since the end of July 2008 - every 3 months roughly. The electrodes have a lot of solid white stuff that collect at the back and part of the front to the point that the mist isn't showing anymore. The CP setting is 6. The service tech thinks that the white stuff is calcium but hasn't got it confirmed. He replaces a lot of these electrodes, all with the same problem After the second replacement, I emptied the tub and filled it through a carbon filter. The pH and Alk levels have been well balanced throughout. We use the tub every night we are home. The store recommended Best Defence - it ended up clouding the water quite a bit (Easy Clear wouldn't clarify) and it turns out that Best Defence was making the phosphates skyrocket (2500) We seem to be going through a filter every month as well. The water gets a little cloudy over time and replacing the filter seems to clear it up overnight. My questions - Is there a way to test the level of calcium in the water and what level should it be at? How do we control this? Up to now, the electrodes have been replaced under warranty but we did have to pay for one of the service calls. What else can we be doing to not have to replace the electrodes every 3 months? The store is now recommending Spa Perfect and the service line mentioned AquaFinesse. Thanks -- Scotte
