pH port No Bueno

DLuce510 · Jun 21, 2016

One of the pH ports on my Apex is deffinitly not working properly. I've tried to calibrate it several times but it will settle then over the period of hours just keep getting lower and lower. The pH/ORP port works great but I need one for my Calcium reactor aswell, any thought on what I can do to fix it instead of having to get another module?

I would open a ticket with Neptune....they should be able to help you out. I do not know of anything that can be done to resolve without replacing the module. I assume the probe is fine since it works in your second PH/ORP port?

Yes sir, it was a bit of a head scratcher. I believe I've seen another thread where somebody has had the same problem a while ago. I was afraid that was the only option. Probably better to just get a PM1.
