I purchased a tunze ATO and at first it runs fine. after an hour or so, i finding that its sucking all the RODI water out of the 5 gallon bucket. Is it the position of the rail in my sump? Anyone else have issues where after a few hours, there finding the reserve tank is empty? I was thinking maybe bubbles were the issue, but there are no bubbles on the sensor

based on what i was able to find through google, there may be a siphoning effect happening..i can fix that with a one way valve. should that fix my issue. not sure if its a siphoning effect im experiencing. right now what i did was use two five gallon bucket filled one with water and put the sensors in the other bucket. lets see what happens
The manual discusses this problem and I mentioned it in your other thread. You need to route the top off hose up to the tank. Pump the water into the overflow box, that is ideal as it mixes it on the way down to the sump. Make sure the hose is not touching the waters surface. A check valve will not work. The water is flowing in the same direction that the valve would open. Gravity can never fail, just set it up as shown in the manual and you will be fine.
actually I think I got it fixed. I think it as the location of the sensor. I did a little experiment last night. I needed a control and I tested for one variable. I set up two buckets. One empty. One filled with water. The tunze worked gr8. So either water movement in the sump or airbubbles from the protein skimmer was the issue. Will keep u posted
Thank you for your replies. I just read your reply on the other thread..i recreated this thread because i thought the subject was too vague on the other one. I set it up as the manual suggested. I think it maybe have been that the sensor was too close to one of the perpendicular walls of the sump or it was air bubbles...last night my tank does 5 gallons of kalkwasser into my tank so i removed the kalkwasser and just using rodi until i get this straight..I was wondering if my sump may be too small and that the protein skimmer is causing too much turbolence in the sump..I dont think that is the case, but it was an idea. I will see how today goes with the rodi..I do not think its a defective unit.
