So over the past few weeks I have tried to really pinpoint my salinity levels by using my conductivity probe. At first a few months back I hooked up my p4 and then just basically set the probes up and that was it. Flash forward 7 months or so and I began to try to redo everything and actually get more use out of the p4. One of the most important aspects I felt was the ability to pinpoint my salinity levels to give me an idea on where my tank was standing at the time.
I am having a hard time both getting an accurate reading and or just really having the probe stay still and not fluctuate. I have tried to calibrate it first with a tolerance of 1 and then with a tolerance of 2 thinking since it was in my tank for a few months maybe it has aged. Well now I am just stumped. the reading at this time in my tank reads at like 1.014- 1.016. This is way too low and no way my tank is at this level. It also says something similar when I make fresh saltwater at the correct measurements of 1/2 cup per gallon of water. ( instant Ocean). So now I have been determined to figure out where there problem is with this probe. @Ditto Suggested I put the probe in the calibration fluid after it was the same temp as the tank water and I did. It slowly climbed up to 50.ms but then it kept going up from there whilst sitting here typing this. its been sitting in the fluid for about 8 mins and it currently says 56.1 ms.
What can be my problem? Is this normal? Theres just no way this fluid is gradually increasing unless it is and I wrong. I have no clue whats going on and have calibrated multiple times although it seems to always seem to be either really low and or seems to be a problem with my probe.. it is now reading 56.4 since typing this...
