I had to drain my tank last weekend to get a fish out. I drained it into an old DT I had in my basement. The tank was too narrow for a 5g bucket so I used my ato to pump the water back into my tank, which went great until the alarm tripped alerting me the ATO pumped a lot of water. With my previous ATO, the solution was simply unplugging it for a minute or so, and then it would reset when I plug it back in. With the Tunze this did not work. Does anyone know how to reset this? Do I just turn off the high water level alarm and then turn it back on?
