Hi all, I've been looking into TDS meters recently as I'm interested in having something continually monitoring my TDS. My question is, what sort of problems would there be with constantly leaving a tds meter in the tank to monitor TDS? Obviously algae and stuff would grow on it after a while, but periodic cleaning should be fine. I'm more concerned about corrosion and the sort. I found this site (EC/TDS/PPM Meter). Any thoughts would be appreciated.
