I'm going back to Costa Rica in a few days for almost 10 days. My ATO is in place and I have a caretaker & a backup caretaker. There is no TV or computer where I am going -\-a person needs to unplug at least once a year! My tank should take care of itself. I just need someone to feed, empty the skimmer cup and fill the ATO water reservoir once a week. Did I leave anything out ?
