The results I'm getting from the Salifert Alkalinity test seem to be odd. It's a new test and has a exp. date of 2014. I've noticed if I do the low resolution test I get a higher dKH vs. the high resoltuion test. Which is more accurate? The test using the 4ml sample? I performed the test twice each way and got 9.3 dKH (low resolution) and 8.75 dkh (high resolution). I know the test is being performed correctly as I've tested with salifert kits serveral hundred times. Does anyone have a contact email for Salifert? Thanks
