I know there is nothing better.
And I know what I will end up doing is first some troubleshooting to determine if the problem is one sensor, 2, or all three. Probably just the fresh water, it's giving the worst readings, and is physically the lowest of the three.
It's been many months, so I don't think drying out will be my answer.
I wish I had better access.
I wish Garnet would have met me even close to half way, I'd happily paid a hundred plus the shipping to go in there once, replace all 3 in an hour, and be done with it.
And yea, they were fine until I had the audacity to clean my WET bay...
I did find a site selling the 12" sensors for $54, half what garnet sells the 14" for...
