So my conductivity probe readings are all over the place. I've calibrated it multiple times (With the solution the same temperature as water) and it reads correct in the calibration solution. Out of the solution and in the tank the salinity swings from 32.5 to 35. But typically swings 32.5 to 33.
When I double check it with my $20 refractometer it reads 1.026 each time no mater what the conductivity probe says. The refractometer has also been calibrated multiple times.
So which do I trust? All inhabitants seem to be doing perfect. But the difference 1.022 and 1.026 seems out of the norm.
