well, i just checked the water in the reservoir and to my surprise it was 35ppm and that's the water that feeds into my tank!! i guess it just slowly built up in there. so, a quick drain and refill every now and again "cleans" up that problem easily enough. hope this helps someone else.

good one!! my reservoir gets a funky smell every once in awhile which is a good reminder to clean it out or at least let it dry out overnight. Never checked the TDS though, I think I'll try that
