I got a salifert kit from Nicki (Thanks!!!!) The reading on it show that the PH is between 8.0 and 8.3
The 2 API kits I have are showing the PH at 7.4....
The Alk is about 161.1 or 9 dKh
I just calibrated my refractometer (thanks WIll and NIcki) and the salinity is at 35ppm (1.0264)
Not sure what to do about the PH. Should I throw out my APIs and trust the Salifert?
Thanks for the help
