I have tried all suggestions and followed instruction and cant get it to caLIBRATE... is this a known issue ?

Did you start a ticket with Neptune? It's probably your best bet. Their customer service is fantastic

Heh, same here. I had to run a manual calibration originally (early January) and it worked. Then tried to recalibrate it and nothing worked. The auto mode doesn’t work at all and manual mode has the dry settled number at 759 and in solution it settles at 740....

If you find a solution, I’d love to know it.

Hi,

I also had some issues with the salinity probe, but as others told in previous replies I used the ticket system from Neptune Systems and the support was really fast and helpful. They sent to me the steps for running the manual calibration and I had to send to them the result of the different steps. After that, the probe works fine and pretty steady.

The trick is to use your actual tank water instead of their solution. Like after the dry step, put it into your sump instead of the 35000 solution..... will set current tank conditions to 35ppt.

(Of course this assumes you’ve checked the tank and it IS at 35ppt)

Do not trust that probe. It's well known to drift even if calibrated correctly. Some have no problem but most know to NEVER TRUST IT.

The best way to use that salinity probe is to disconnect it and place it in the garbage.

Yes, that is how I got mine to work.

I just had the same thing on a 6 month old probe. Spoke to Neptune yesterday with remote support and they are going to RMA it. Lets hope the new one lasts longer.

I’ve never been able to get my Neptune salinity probe to work. No matter how many times I try to calibrate it.

I’ve just given up on getting it to read 35 ppt and for some reason it reads 28 ppt when the tank is actually 35 ppt. Now I just use it as a way to detect any variation from the 28 ppt it reads as a sign that something is wrong.

I agree. With an ATO, measuring salinity manually once a week works well.
