I'm thinking about geting an electronic PH tester. There is the PH/EC/TDS combo unit and there is also a PH/ORP(Redox) unit. From what i have researched EC and TDS generally relate to hardness(but not as simple as that). Redox is more of a measure of the water quality. I don't completely understand this stuff but i think the Redox testing unit may be the way to go for me.
What do you guys think is more important to have EC/TDS or ORP?
