Think you might actually be right rusty. Just went and checked the bucket I have filling now with the liquid test and it came out between 6-6.5. Checked it with my meter and was reading 8 something.

Any idea why the meter would be dead on in the calibration solution and be so off reading the water? Going to go ahead and order a new one, need a tds meter anyways.
gbf4ever Reviewed by gbf4ever on . New RO system raising ph Just picked up a 100 gpd ro system. Ran it for about 40 minutes first to clean it out like the instructions said, then filled up a 5 gallon bucket. Ph'd the water after and the filter raised it from the 7.3-7.5 range to 10. Is this normal? Do I just need to let it run awhile to clean it out? Rating: 5
