So I did a tank rebuild a few months back and just got around to putting new probes on my Apex (old version). I have multiple problems:
First, I have two temp probes. Probe "TMPX4" works flawlessly which is great because it controls my heater. Probe "TMP" is crazy. It gives me readings that are spot on sometimes and then it will spike to 170-180 degrees on Apex Fusion. This happens multiple times a day. See graphs on pic. I've tried calibrating it, but nothing works. Why? How do I fix?
Second, I installed a new Salinity probe yesterday afternoon and I was getting correct readings on my Apex display when the probe was in the calibration solution, but when I transferred it to my sump it dropped and is holding steady at roughly 29 PPT. I tried calibrating it a couple of times and each time it would read correctly while probe was in the calibration solution, but then drop when I put it in my sump. I have back-checked it with two different refractors which both confirm my salinity is 1.026/35PPT. What gives?
Lastly, I also installed a new Ph probe and am getting similar readings to my TMP probe. It fluctuates wildly from correct readings of 8.00-8.20 to incorrect readings of 18.00-19.00. This also happens multiple times a day and typically when the TMP probe is simultaneously out of sorts. See pics below of my current readings. You can see from my graphs the spikes that I mentioned above.
ORP works great. No spikes other than when I was messing with it yesterday while work on other probes. It works great and was super useful when I was running a Sulfur Denitrator on my previous tank build.
Can anyone offer any advise on how to resolve my issues with my Temp, Salinity, and Ph probes?
