Ok an mV update
This all got me thinking and I dug out my research papers from when I developed a cold plate ozone unit in the UK. To do this I did a lot of research into Mv (ORP)
The ozone unit can still be purchased today by the way

But only in the UK.
Where was I? Oh yes Mv!
One thing of interest is the relationship of oxidants in water to the reading of ORP with a probe. (Ozone being one of the most powerful oxidants). For the probe to read it has to build an ion (molecule) field up around the element. Naturally this ion field will be unique to the compounds found in the water. And this is why new or calibrated ORP probes take a while to settle in.
So without getting too indpeth, my initial feeling for seeing a huge drop in the Mv when changing over to TMC pro is due to the ionic differences between the salts. What the differences are I have no clue, me no chemist

but it seems likely the connection is somewhere in this region.
Interesting text -
Oxidation Reduction Potential (ORP) is, simply put, an indication of a solution's ability to oxidize or reduce another solution. It is a ratio of oxidized species to reduced species in a solution containing both. Some commonly used oxidizers include chlorine, ozone, bromine, sodium hypochlorite, and hydrogen peroxide. Examples of reductants include sodium bisulfite (also known as sodium metabisulfite) and sulfur dioxide. The terms "ORP" and "Redox" are both commonly used and are interchangeable.
So in this case maybe there are less oxidents in TMC for example Bromine. Using Bromine as an example, IF RC has a higher level of Bromine there are more oxidants present and as such a higher mV would be sustained, which ever way I now am curious if TMC has less oxidents in it than RC, and is this the reason for the mV drop?!
The question then would be - Is it good to use a salt with a higher level of oxidants or a salt with a lower? Well i guess this depends on what the oxidants are??
Ok now getting into chemistry and where I stop typing!
