Hi guys ! Nice to see you😁
I had some problems and really need ur help.
I used EI before but it seems not work for me so I decide to try with PPS Pro. I have some questions
1/I change my water and start dosing. The problem is after change water my tank TDS is immediately higher than tap TDS...
I purchased some RO water from my LFS.
I tested the water with my TDS meter and received a reading of 9ppm.
Shouldn't the TDS reading of RO water be 0?
I don't think this is a meter calibration issue, as I have a Zer000 water pitcher that produces 0ppm TDS water. Using the same meter.
