PH Probe with Grounding Probe Problems

Post by brennyn21 »

So whenever I put a grounding probe in my tank it make my PH Probe read 2.6 or something really low. I did buy a brand new PH probe and it did the exact same problem. Another odd issue is when my AWC (Auto Water Change) turns on my ph again drops to 2-3 range I thought it was super odd. I made sure power cord was no where near the ph probe and cable and still didn't make a difference and the Water out line and water in line are in the sump and ph probe is in main display and if I disconnect the water out line from the pump it fixes the issue just not sure what is causing it. Im using a Stenner dual head dosing pump for auto water change

I had some issues with stray voltages/grounding in the past affecting my salinity probe. I ended up putting the probe in a small cup and have tank water drip into to cup, and overflow back into the sump.
