In-line salinity probe problems.

[Tony Dreasher]

OK Apex friends I have a problem I need some advice on.
My salinity probe has been reading spot on and I want to put it in a in-line probe holder. It’s dead on until I feed and turn the pump off and it goes up into the high 40s low 50s and won’t come back down. If I take it out and put it back in the tank it goes right back down to where it should be.
Any advice?
Tony.

following. I was considering going inline. I have tried so much to dial my salinty probe in.

That’s usually an indication that there are air bubbles in the probe.
