Apex question

[jordan10]

Hi so just got a Apex and setting it up. I calibrated the salinity prob like it said. But it's showing 3.2 on the screen is that right?

I had the opposite issue with mine, it read high, but was able to fix it with these steps from @rkpetersen.

Apex salinity probe calibration

The Apex conductivity/salinity probe is not of the best design. With that acknowledged, here's how to get yours working consistently and well. First, if you've done a calibration before and it seems to be messed up, simply recalibrating it is likely not going to do the trick. You need to reset...

No, That's not right. Something went wrong

Now it's bumped up to 29.6 so I'll let it sit little longer then I'll try looking into them steps. It should be around 35 right?

If 35 is what your tank is. The salinity probe is very sensitive to microbubbles, so it needs to be in a place away from them. I get the best results when I tilt the probe holder so that the tip is facing away from the flow of current through the sump.

Also, any changes in readings take a few mins to show up on fusion. It's not instantaneous.

Thanks and round 34 and yea I read that about the air bubbles. Thanks for ur time.
