Apex problems

Ph will be fine then drop like a rock or shoot for the stars. This is my 3rd probe it's brand new. Starting to feel like my unit is bad.

Where is the pH probe located in your setup?

Sump

Which part of the sump? Do you dose in the same area as the probe? any powerheads near the probe? How's the cable run to the apex unit, near any power cables? Apex Classic or 2016?

I get major PH dips when I dose in the same chamber. Usually temporary, but it will look like a poltergeist attacked the Apex. Also had issues with stray voltage from a heater that was on its way out. Numbers went weird when it kicked on.

Edit: you may have some issues, there is no daily PH swing @ all! The photo is my setup today.

Silly question, did you calibrate the new probe?

 

[aj741986]

Yes it's been calibrated. It's by a heater. Never dosed by it. It will work fine stay in low 8s then drop instantly or jump up instantly. My tank has a ground prob in the overflow and one in the sump
