Ammonia slowly climbing?

[PRock]

Okay, I'm done with this Seneye thing. I shutdown my computer to install some new hardware, moved the USB port the Seneye is plugged into, rebooted the computer and my PH tanked?!?

It was out of the water for oh, about 30 seconds as I re-routed the cables. I have ammonia again! By the next reading it was showing ammonia, and it went over the alarm value of 0.05 ppm within an hour and a half and has staid there pretty much ever since. So I'm going to go out on a limb here and say that according to the Seneye, Air = Ammonia.

Re seated the slide under water - guess when!

If the seneye is using an optical sensor to measure a color change in a chip (seems likely) then small air bubbles could totally change the apparent measurements.
If so, that's a pretty annoying implementation - air bubbles causing a false high ammonia alert.

These two threads should meet
***a seneye that held in the hundredths, and I thought it was neat they mentioned natural levels in the thousandths ppm vs hundredths or tenths

How accurate is Seneye for NH3? How impactful is 4ppb Nitrite?

I've been struggling to come to grips with some odd test results. My tank is now 3.5 months old, but it has gone without fish for the last 2 months following a series of seemingly mysterious fish deaths. I purchased a Seneye to monitor Ammonia in the tank, but it is always reporting ammonia...
