you should always use 7 and 10 for your Tank PH and 4 and 7 for your Reactor PH.

You will find differences if you switch the 2 that is normal. You need to calibrate to the closest numbers to what your measuring.

More precisely, you need to choose buffer solutions that bracket your target pH. Salt water is ~ pH 8.2 so you'd choose pH 7 and pH 10 as your buffers. Your calcium reactor has ~ pH 6.5 I think and that would be pH 4.01 and 7 buffers.
