    Salinity probe slowly dropping, can't solve micro bubbles?

    I have calibrated this thing 3 times in the first week now. In the tank temperature matched with temp compensation turned to 2.2. Still, it slowly drops each day until I come home and give it a quick shake/tap in the tank. This is in the sump in the lowest flow area I can find. Is there any other solutions? or a special chamber or something? Can you guess what time I tapped the probe to get the bubbles out?

    Sometimes mounting at a 45 degree angle with the hole pointing up helps.

    That did not work. When I tip it up, I get very high readings 44ppt+, unknown why. I have no real good low flow zones in my sump and I never made a good microbubble trap... perhaps I have to put it somewhere else? or is there a device? This is basically worthless data to me, and salinity/temp is all I really care to see until the ALK monitor is out.

    Do you mean when pointed up the reading temporarily changes and goes back immediately when pointed down, or do you mean once you tipped it up the reading stayed at 44ppt.

    Correct, very high and stay, then put it back in holder, back to 35ppt after a good shake, then slowly drop over day

    I would contact support. Maybe the probe got damaged internally.
