Have a tunze osmolator that’s only a few months old. I always clean off the sensor however I went away for 2 days and came back and noticed the level was low in the sump and the sensor had dried salt all over it. Thought it was a freak thing but it’s been happening once a week now. I reached out to bulk reef but they never replied then just asked for a review on how the help they provided went. Curious if anyone else has had this issue.
