ug, people. Yeah You let it run for a few days at least. Some people let them run for a month, I've personally let my 10 gallons run for a week in the past and been fine with that.
If you have a water testing kit use that to determine when your cycle is up. Wait for the nitrites to go down (although you have to have a test kit that can measure that). Some tanks cycle faster some don't.
Feel free to message me any questions, I'll try to help the best I can!
