AquaController3 and 100 mV ORP delta w/ light

C

chrisk

I'm a little confused. I recently got the AC3 in the group buy and have been running it for the last few weeks. I've noticed that when the tanks main lights come on, the ORP drops to ~ 310mV. When the lights go off, the ORP immediately jumps to 410mV. I've tried turning PH compensation on / off with no noticeable changes. There is always lighting over the refugium. Anyways, trying to see if this was normal so I can determine how to setup my ozone controller.
 
No, mine isn't affected by my lights.. there is a bit of natural ebb and flow, but more in the 10-15mv range, and especially when I feed the fish or dose iron or iodine to the tank.

Do you have a grounding probe installed? Might be worth a try to see if there's some stray voltage.
 
I don't have a grounding probe, however, I re-did all of the wiring and it seems to alleviate the problem. Thanks for the suggestion!
