Do these salinity probe readings look normal

Mine will be 3 weeks old Monday. Still don't know how it suppose to behave. Throughout the day it randomly jumps between 33.9 and 34.2 mostly stays at 34.1 figure that is the number to go by. Afraid to even touch the probe before its gone crazy jumped as high as 48 so now got it at an angle seems to work best.

I think you stare at your probe values too much! LMAO! As for whether they are normal.. Sort of. Your does seem to bounce around more than mine does but it could also be the fact that it's still pretty new. It could also be a case of slight interference from something electrical near by or slight amounts of DC voltage in the tank water. Also keep in mind that conductivity will vary slightly due to temps and other factors. Those variations are in your case are slight enough that they wouldn't even be really noticeable on a refractometer. The Apex uses temp compensastion but that is only a loose guideline and slight variations during the day can be expected. In fact, I would never expect to see a flat line conductivity reading. The CondX probe should only be used as a guideline.
This is mine. It could use a calibration as I havn't touched mine in over a year but it's pretty close to the 1.024 to 1.025 that I run my tank at. Mine only serves as part of my failsafe anyways so I never pay any attention to it.

If you have Jebao's in your tank, I'd bet that is the cause for the erratic lines on condx readings.. Those pumps could be leaking a bit of DC Voltage in your tank or it could just be some other interference like I mentioned above. I certainly wouldn't worry about it though. Those variations in your graph are so slight that it would even read on a refractometer like I mentioned above.

That's what I got a Jebao WP25 that is two years old and a real POS running less then 50 percent its performance. Cleaned done everything giving up on it. Thinking about replacing it with the Apex Wav but not sure if the $300 includes just the pump or everything do you know? Thought about the Maxspect gyre but heard they are cheaply made.

The wave should include everything you need and will be plug and play with your Apex.. There is also the Tunze's.. I've beaten the hell out mine for the last 5 years and they are damn near bullet proof. I haven't even cleaned mine in 2 years. They seriously look like rocks because of all the coraline that has built up on them. You can find them used for less than the Wave but the Wave should be a great option and at it's price point, it can't be beat. Without a doubt, the Wave will be leap years ahead of the Jebao.. Frankly, I'm surprised you got 2 years out of that thing. You've actually gotten some good use out of it.
