Electrodos de repuesto para SPA iónico

We did some testing on our electrodes, no feet in the water, just electrolyzing tap water. One unit (stainless steel) ran for 400 hours! 200 hours with the doubler, and 200 hours without. Soaking and cleaning every day. When a body is in the water, I would expect it to wear out faster. We have noticed that acidic people with cancer and other diseases pit the electrodes faster. This is just an observation, without any statistical significance. We have seen competitors' units will fail after 5 hours of use. We have found that some competitors' units put out lead, one gave out 400 ppb of lead, with no feet in it. That was quite alarming!
