I've had Tunze 3155 for about four months and it is connected to a timer to pump water 4 times a day to avoid constant pump buzzing (the tank is located next to my work desk and the timer turns the pump on when I'm not there). A week ago I've noticed that the water level in my return pump chamber is considerably below the ATO controller. Evidently, every time the ATO is powered up, the pump works for around 30 seconds and then stops with green LED showing "Level". So, it adds some water four times a day, but not enough to keep up with evaporation. This issue, probably, started a while earlier, but it took some time for the water to drop to a noticeable level.
I do use Kalkwasser mix of about one two flat teaspoons of kalkwasser for a gallon of water. Not sure if it matters now though, since the pump flow is good when it works.
Does anyone have any idea what is happening?
