Tunze Osomlator 5017 ATO - Water level Issue

[baktabiznis]

I have a Tunze 5017 ATO in my Red Sea Reefer 250 sump that's about 3 months old and I can't get the water level in my return to stay consistent. It's like it has a mind if its own. I will have the water level set and the ATO will come on and keep it consistent for a while but then the water level will being to drop. If I unplug and replug in the ATO it will kick on and try and catch up but never does. It will even say "low Level" and begin to pump but soon after goes green and stops but the water line will barely be above the return pump. The optical sense is mounted at least 3" above the return..

Any help is greatly appreciated.

Thanks,

Is the tunze new or used?

Might have a bad controller.

I am not sure if this applies to your system, but if you have large tank and your osmolator is set on "NANO" then it might cause problems like yours.
"Setting the pumping power
“Dosing power”
The dosing pump can be set by means of the internal
potentiometer in the controller (4).
“nano” setting: small aquariums, for a maximum
pumping height of 1.0m (39 in.).
“medium” setting, delivery condition: medium-sized
aquariums, for a maximum pumping height of 2.8m
(110 in.).
“max” setting: aquariums up to 1,000L (264 USgal.),
for a maximum pumping height of 3.9m (154 in.)"
