I amnow on my second ORP probe for a Red Sea Aquazone 200 ozonizer. The first one worked well and accurately for about 4 months, then started reading high (380) in regular tap water (orp usually around 80 where I live) Well, got a new one, and it read correctly for about 3 weeks, now it to is doing the same thing. I doubt the probe has gone bad this fast. How can I clean the probe? I have read that there is cleanign solution available for this, but is there some other way to do it, or other common checmical to use? Thnaks.
