Howdy,
I have purchased a portable pH/mV/temp meter and cannot find any info on the web regarding what the mV reading should be in aquarium water - there is a bit of info reagrding the mV range for reef aquaria, but nothing for fresh or discus tanks that i could find. pH/mV readings for 3 of my discus tanks are as follows: 7.2/-25; 6.91/-7; 6.49/17. MilliVolt readings are a measure of the ion levels in water and for the chemists amongst us (not me tho) oxidation/reduction potential of the water. These readings do not seem to relate to GH levels as they are 125, 125, >214ppm respectively. As for my other chichlid tanks the mV values range from -45mV to +63mV, and Adelaide water is -46 and RO water is +37. Any ideas or info would greatfully received.
Cheers
Sean
