Hi guys,
Im brand new to Neptune and Apex. Just installed my first one on my 220G reef yesterday. I read all the online guides and the FAQ and calibrated my conductivity probe accordingly. I first tried using the automatic method but it would never find an acceptable reading in the 53k solution.
I tried a manual calibration (wash the probe in ro and then lightly dry off) matched the 53k temp to the tanks (79F) and then ran the manual calibration.
Success (or so I thought) it read 35.7 for about an hour and ever since its been climbing up and up and up and is now at 90. I can confirm the tank is somewhere between 33-35 from multiple other readings.
So whats gone wrong here? Ive tried lightly tapping the probe to release bubbles, but no change. Cant re-calibrate now as I threw the solution away as advised to only use it once. Bit disappointed that even following the instructions exactly it doesn't seem to calibrate correctly for a $1200 piece of kit (UK price)
So what next? Shall I order more fluid and just keep re-calibrating until it works?
Any help would be great - thanks!
