tror du får problem med den där till 430 liter. Den kommer inte palla med att fylla upp tillräcklig nivå på den korta tid den är på, vilket utlöser en säkerhetsbrytare om jag förstått det hela rätt. För att återställa brytaren måste du kapa strömmen till osmolatorn och plugga in den igenDetta för att den inte ska kunna tömma din dunk om nivåvakten hänger sig. Därför den bara är speccad för upp till 200 liter. Beror ju iofs lite på hur mycket som dunstar i ditt akvarium Så här säger instruktionsboken (http://www.tunze.com/fileadmin/gebrauchsanleitungen/x3152.8888.pdf) "To set the metering quantity for aquariums up to 200 liters (53 USgal.), the jumper on the controller can be adjusted. Disconnect the controller from the power supply, and then detach it and open the case by simultaneously applying pressure the points (1). Change the jumpers on the circuit board as shown in figure (2). With this setting, the Osmolator® nano features an electronic monitoring, which stops the metering pump (3) after 3 minutes of continuous operation. This avoids an overflowing of the aquarium, for example, in the event that the sensor is blocked. After the time monitoring has elapsed the metering pump will receive a short pulse in a time interval of 10 sec. This indicates an exceeding of the set max. dosing time. After switching the power supply on and off, the Osmolator® nano will be ready for operation again. The maximum dosing time is also exceeded when the storage tank is empty, and the pulses of the metering pump indicate that the tank needs to be refilled." "Maximum delivery rate during 3 min. Dosing time: (1) At a conveying height of 0.80 m (31.5 in.) of the metering pump (water level between the storage tank and hose end in the aquarium) a maximum volume of approx. 3.2 L (0.85 USgal.) will be refilled. (2) At a conveying height of 1.15 m (45.3 in.) approx. 2.9 L (0.77 USgal.). (3) At a conveying height of 1.30 m (45.3 in.) approx. 2.8 L (0.74 USgal.). (4) Maximum conveying height: approx. 3 m (118.1 in.) Caution! These values only apply for the original Osmolator® nano 4x7 mm PVC hose with a length of 2 m (78.7 in.). With a shorter PVC hose the metering amount will be higher. Note: The pump performance data can vary by up to 20%."
