I don't ever test my water except calcium/alk, don't even have the other test kits. I know it's bad practice but I figure my corals or nems would let me know if something was up even before the fish.....

your corals can take a swing in ammonia and nitrate and not tell you but it can kill your fish. You need a test kit and that is bought before you get your first fish.
Are you spraying anything in your room during the day? example: deodorant, furniture spray, windex, medication
