Thanks, I saw in a video this guy doing a test of the various "waters". You just dip and read. But it wasn't a stick you dip, like ph strips. It made sense bout the readings, and how it would let me know when to change out media in my RO
. But I'm not sure after reading descriptions of which kind I would need or what I'm looking for one to do.
being total dissolved solids, what solids would I need to be watching out for and I can't see where it says the measurements of each solid, or is it a measure of any solid and doesn't matter what kind, just that they are down?
Does one kind measure this kind and another that kind?
