For some odd reason, my TDS meter is giving me a high reading overnite. I picked up some 1382 PPM stuff but found out it will not work for me. Do you carry any 342 PPM?

Do not stock the 342 PPM. Let us know and we can probably order it.

IDK what's going on now. I purchased some distilled water and it reads the same. I think my meter is shot.
