Comments: Arrive quickly. Easy to calibrate and read much more accurate than the last one. Just a little upset that my questions to Neptune Systems were blown off. Felt like since i have the Aqua Jr. and not the new APEX then i'm not worthy of help.

Comments: I had terrible problems calibrating the unit. It just wouldn't work. I had ph reading of 16 and then 4. Customer service was amazing and after a number of back and forth emails the tech asked me if I had taken the shipping cover off the probe! It's amazing how accurate it is if you take off the cover! There was no literature in the box that it came with so I never knew!

Comments: How easy is it to calibrate an Apex probe? Very easy. Just follow these steps: 1.) fill two small containers with RO/DI water (used to rinse the probe between steps). 2.) next remove the protective cap from the probe and place in one of the 2 containers. 3.) connect your probe to your controller. 4.) press the Enter key on your Apex AquaController display and select Setup. 5.) next move the cursor to pH Setup and press the Enter key. 6.) carefully open your pH 7.0 solution. Remove the probe from RO/DI rinse and place into the solution and swirl a few times. 7.) now press pH Calibrate from the display screen. Allow the probe time to acclimate from the RO/DI rinse to the pH 7.0 solution. Review the display. You'll see the probe calibration proceed e.g. from the pH of the RO/DI rinse (typically 5.X) to 7.XXX. 7.) once the calibration is complete press the "Save" key. The pH 7.0 calibration is now complete. 8.) now remove the probe from the pH 7.0 solution and place into the same RO/DI rinse, swirl, then move to the unused RO/DI container to remove remnants of the prior solution. 9.) now select pH Calibrate once again from the display screen. You'll notice the default value listed on this screen will be 10.0. Your Controller recognizes the fact you "saved" the 7.0 10.) open the pH 10.0 solution. 11.) remove the probe from the 2nd rinse, insert it into the pH 10.0 solution and swirl a few times. 12:) press pH calibrate and wait for the calibration to complete. You'll see the calibration value move into to 10.XXX range. 13.) once the calibration is complete, select "Save." 14.) now remove the probe from the 10.0 solution and rinse in succession in the RO/DI containers then place in your sump. 15.) VIOLA! You've properly calibrated your Apex probe. Enjoy!

Comments: Seems to work great...I had the standard probe for a couple years and noticed that the pH was going wacky. We will see how long this works. So far so good.

Comments: The Neptune Systems PH probe is an excellent product. It came packed extremely well from Marine Depot. I calibrated the probe to the head unit with no issues and it started working flawlessly. I would highly recommend purchasing the lab grade probe.

Comments: I bought 2 of these high grade because I knew they would last longer and be more reliable. Wrong. one of them already went out and nuked my SPS reef. it was solid registering 6.82 and after a couple of hours of troubleshooting I found the reactor to be down at 6.02..wow...very disappointing. luckily they took it back and sent me another in exchange. I will be second guessing from now whether i need the lab grade or maybe just by 4 of the lower grade so I'll have a couple extra around in a pinch. I rated this below average because of the price and you might not get what you pay for. Luckily it didnt kill any of my tank inhabitants.

Comments: It would have been a little nice if it included instructions. Is it calibrated? Any special precautions that I should take? pretty weak! Not too many options when it comes to probes, so not much I can do I guess.
