Conductivity replacement

[LilysDad]

Is there any other conductivity probe that’ll replace the original apex my original isn’t working well and I don’t want to buy a $200 one

I’m not doubting the diagnosis, but how do you know it’s a probe problem?

Does it responsively read at all? Such as different in air and tank water?

Not know the controller, I can’t be sure it’s a probe issue, but the first thing I’d do is soak it in vinegar overnight to see if deposits on it are an issue. Gentle toothbrushing of it may also help.
