Osmolator Malfunctioning

[sclaussen]

I installed my osmolator this evening and it took a while for the pump to begin working but it did. I am building a 90g but am testing the tunze on my 29g biocube. I have the dark probe on the bottom magnet in the back left return section of the biocube. I have the float on the top marget almost 6 inches above the black probe. The system runs fine for a bit, refilling back up to the black probe, but inevitably it decides to continue filling above the probe. The floater then stops the system, the alarm goes off, ... Is this a setup issue of some type, or do I have a bad probe?

Thanks,
Shane

Make sure the reservoir is below the tank and that it is not a siphon causing the problem. The optic sensor has no way to differentiate between air bubbles and being out of water so it is critical that the section the sensor in is free of bubbles. It is not impossible the sensor is defective. We recently changed the sensor to increase the accuracy, sensitivity and reliability and some of the earliest of these new sensors are just too sensitive, they work in a perfect system but are too easily affected by air bubbles. The key is to have a nearly bubble free chamber either way, even the current sensor or the oldest sensor will not work with more than a few occasional microbubbles.

Ok Roger - I'll play around with it again today and look to see if any microbubbles exist - I don't think there are any - but I am running the ato tube back into the same section the optical probe is in so maybe that is creating some splash bubbles (I was letting it drop in so I could hear it running) - I'll run the tubing to the neighboring section and try it all again. Thanks for the quick response.
