apex ph reading incorrect

[swnoob]

For the last couple of weeks my ph reading has been acting up on its own. As you can see by the picture it will give a false value instantly and sometimes fix itself after a few hours.

Most of the time I have to power cycle my apex to get working again. I hate doing that because in the past I have lost all programming due to power loss.

The probes are only a few months old and I've also switched the probes on the base unit to confirm that it happens on the same connection with either probe.

This is one of the reasons I recently switched to 2 part dosing and took my calcium reactor offline. Afraid either probe may fail and the reactor isn't dialed in correctly leaving me with no safeguards.

Has anyone run into the same problem?

Thanks

If you switched the probes and it still happens then it sounds like it may be an issue with the port on the brain unit or software related. Are you running the latest software? Are all your modules up to date?

Not that it's the problem but if you need calibration fluid I have a bunch.

My apex is running firmware version 4.40_3A16. Just checked their site and it looks like 4.51 would be the latest. Apex fusion usually alerts me when there is an update available. Weird.

The apex module list says (OK) on all.

I'll give the new version a try and hopefully that resolves my problem.

Have plenty of calibration fluid.

Thanks!

Although the modules say OK, there may be an update for them. Select the module, make sure you check the box Update Firmware and submit. I do that every couple months to ensure the modules are up to date. My eb8 lists SW12 and display SW11

Happened to me a long time ago. Sent to Neptune and it was bad ports. $100 later and it was working normal again.

try messing with the connector works too. mine was not working properly and just wiggling with the connector to module fixed it.

I'm hoping the firmware update will fix it. I would hate to send it to Neptune for the 4th time. Previous issues were unrelated.

I may just tough it out and upgrade to a GHL Profilux in the future.

Tried that with no luck. Once it starts reading incorrectly it will eventually freeze and the only way to get it to work again is if I power cycle.

call Apex, somehow they fixed over the phone for me. I had same issues with both modules and magically fixed by them over the phone.

Tried updating the firmware and that didn't help.

I did delete all the logs via telnet and it's been working for the last 18 hours without any issues. Hopefully that did the trick.

I would suggest cleaning the connection & probe where it plugs in with electrical cleaner. Corrosion could easily cause such a problem. After cleaning some dielectric grease will help keep the moisture out and the connection better.
Personally I use dielectric grease on all my electrical connections and plugs around the aquarium. You can find bout at electronic parts shops or auto parts stores.

Good idea. I'll definitely pick some up.

Thanks for the tip.

I had the old Ac3 and trying to calibrate and use two ph probes was a problem from their product... I have apex now and use two ph probes with minimal trust. I suggest calibrate often and solenoid kill commands on CA reactor...My solenoid stuck open finally and am replacing as we speak ...

The chaps at Neptune know what's up with Multiple Ph probes
