Apex alarm went off suddenly Sat night. PH was low. The tank is fine so I'm convinced it's the probe. It's all over the place; plummeted out of the blue.
I've cleaned it and ran it in a cup of tank water for a while but it won't settle down. Calibration fails with 7/10 solutions on the 10 side calibration.
From Neptune sys:
Bought from my LFS so maybe it sat on the shelf for a while. I'll buy another probe but it's just irritating me a little that it only lasted (me) this long.
Does it seem reasonable that I'd have to replace an Apex PH probe that was purchased June 2023? It's never been dry (fluid was in the cap when I opened it)? First controller/Apex so trying to get a gauge on what to expect. If they only last this long is the cheaper BRS probe a good option?
