TUNZE osmolator ( ATO ) problem !

[jlnielsen13]

Hello Tunze,

I bought a TUNZE ATO system for my 500+ gallon system and hooked it up to my sump in the basement fish room.

It seems to function normally, turning on and off and supplying water to the tank. The problem is by the end of the day (everyday) the "too low" light on the far left is lights up red and then it fails to pump any more water in or work at all.

If I fill the tank up back to level and unplug the TUNZE it begins working again as needed but eventually by the end of the day shuts down due to the "too low" light on the far left.

I have cleaned the sensor and tried everything but can't figure this one out.

Anybody have any suggestions?

Thanks in advance- JIM

Have you checked what power setting its on yet?

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.).

Too low generally means it tried for 10 minutes and has timed out, it could be that more water is needed, the pump speed can be adjusted inside the controller.

I will check that when I get home today- hoping you are correct on that one!
Thanks,
