PH Probe interference

Post by fishi »

I finally calibrated my ph probe. Got 7 and 10 calibration solution and that went well.

I then put my probe in the sump and I noticed my ph was high 8.6 and then climbed to 9. I figured the water didn't have that high of ph.

So i started trying to diagnose it. When i turn all the relays to off the ph probe goes down to 8.2 - 8.3. I turn one item on at a time and everything is good until i turn either my power heads or my protein skimmer on. Then It starts to climb.

The weird part is when i turn those off it doesn't go back down. It only goes back if I turn off all the relays.

Everything is mounted to the side of the stand on the outside via velcro. I have both the lights and the reefangel hooked into a gfci protector.

Any ideas?

Incase anyone finds this searching. My probe was broken. The little ball shattered at the end. Not sure if I broke it previously or when i tried recalibrating again. Ordered a new probe and ph calibration fluid.
