Adding Expansion HUb and Salinity Expansion

[ganjero]

Something else that is connected to your setup is doing that.

Roberto,

When you say setup, do you mean the reefangel controller? or my entire reef system?

I've been watching this for a bit and just want to though in my 2¢.

Do you have an ATO that is feeding fresh water into the sump, possibly close to the Salinity Probe?

Good point, and believe it was somehow close. I will try setting them on opposite sides and see how that works, but if that is the case shouldn't it just go down and then back to 32-34 instead of 44?


Thanks

That is true it should go back to normal and not 44ppt.
Is your ATO dosing Kalkwasser too?
I had my Salinity probe get covered with calcium deposits and it gave me crazy reading.

Placed in a different area in the sump and still have the same issues.

Does anyone know what equipment commonly cause issues with this probe?

Have you checked for stray voltage?

[ganjero]

Measured for Stray voltage. I have a ground probe installed so I removed it, my multimeter shows a reading of 14. I turned everything off and almost every piece of equipment added a point.

When I put the ground probe back in the reading goes back to zero, but I found that if I leave it out the salinity reading stays constant, 5 points off but constant.

Any thoughts?

Do you have another 12VDC power supply to try connecting to the salinity module?

Is this the same salinity expansion I bought off of you today?
