Just opened my new Apex and looking at the red probe, it looks like the fluid has been leaking and the probes is new. Is this an issue?
I am not convinced mine is working correctly. II this now in the aquarium reading 191. I will give it a few days as I have been told they need to settle but if not, I will contact Neptune as clearly a lot of liquid was lost as can be seen from the picture. The good news is that the Salinity probe is now working so that was my fault for not submerging it enough!
try to avoid getting air bubbles in the salinity prob as it will effect the reading. I have seen some reefers make a pouch out of filter floss and put the probes in it so air bubbles won't effect the readings.Thanks. The other issue i have is with the salinity probe. Just calibrated and when I put it in the aquarium it read 35. After few minutes it dropped to 0. I recalibrate and it read 34.9 when I put it in the aquarium and is now reading 1.1. Do these take a while calibrate?
Many thanks. The salinity probe is working fine now so that was a user error! I contacted the company i brought the Apex from and they contacted their supplier. They have kindly arranged for a new ORP probe to be sent to me as they believe it should not be sitting 178 after 24 hours in my aquarium. I suspect the little water that was in the cap was not reaching the probe sensor.
there are numerous PH probes that must be kept wet. Hannah and Milwaukie probes for example..Here's the rub - Apex probes are the only ones that I have ever seen that "Must be stored wet". I did pool maintenance for 15 years and PH & ORP probes were always shipped/stored dry. They can sometimes take a couple days to settle down and read properly though.

I'm trying not to be mean, but you have literally done everything wrong from the get go it seems. I'm not posting to pick on you, but it's situations like this that give Apex a bad name. I would suggest you just return everything now, as you have unrealistic expectations. Your probe wasn't stored "dry". There would have been more than enough humidity within the cap to keep the probe usable. Did you even read the manual? It's pasted below for you and your LFS's convenience, since it's apparent no one has any clue on ORP probes. How do I know no one has any clue about ORP probes? Here's mine at 176 after a healthy cleaning.
Notes on ORP probes: The ORP probe comes calibrated from the factory and should not require calibration in normal use (remove the cap before using). If however you feel you do need to recalibrate it, there are instructions in the manual on how to do it. It is not as simple as the pH probe calibration and requires a special powder called quinhydrone along with pH 4 and pH 7 solutions. Mixing the quinhydrone with pH 4 and 7 solutions gives you calibration solutions of 86mV and 263mV respectively, creating the low/high solutions these probes require for two point calibration. There is much information on the web as to this process and suppliers of the necessary solutions. Page 21 Version: 5.0 Packaged 240mV or 400mV calibration solutions can’t be used to calibrate the Neptune ORP probes because Neptune’s ORP probes require two reference points to determine slope (back to your geometry textbooks, quick!). However, your probe still should read 240 or 400 if immersed into one of these solutions. New ORP probes need some soak time in your tank before they will report accurate data. This ‘break-in’ process on a new probe can take a number of days, perhaps as long as a week. When you first immerse your new ORP probe in the tank it will read 125 – 140 but will steadily increment the mV reading by 2 – 3mV per hour, gradually tapering off to 1mV/hr. Normal ORP response is to rise and fall opposite pH but this won’t happen as the ORP probe is acclimating to your tank. When it stops its steady march and starts the rhythmic rise/fall during the day, that’s when break-in is complete. What number range it settles on is different for every tank. It could be anything between 250 and 400 – there is no right number. It’s more the pattern that develops and exceptions to that daily pattern that you will need to be aware of.
