Don’t forget to actually wash the top off. It was just wiped off. I always finish with soap and water. Gets the stinky vinegar smell. I prefer to use bleach. 1/4 cup in a full bowl of water. run for 30 minutes. I do have to turn the pump on when it shuts down. I dump out the water. Rinse the bowl and grow deck with water. Then I fill it back up with clear water and run it for 30 minutes. I then dump out the water and do a thorough rinse. I make sure the sponge is in during those cycles and thoroughly rinsed because it needs to be cleaned as well.
