Here are the actual pH values for calibration fluid labeled 7.01 and 10.01 at the following Temps in degrees F
59.....7.04/10.12
68.....7.03/10.06
77.....7.01/10.01
86.....7.00/9.96
95.....6.99/9.92
For example, when you calibrate your meter, you set your pH meter for cailbration fluid at 10.01, but at 68 degrees it is actually 10.06. The higher end seems to change the most. Does this actually make much difference between room temp calibration fluid and your tank temp, probably not much, but I thought you might want to see this.
