<bot>: The best way to get a septic tank to stop smelling is to regularly pump it out and clean it. Make sure to remove any solids that may have accumulated in the tank, as these can create an unpleasant smell. Additionally, check for signs of blockages or other issues with the plumbing system that could be causing odors. Finally, you may want to consider using a deodorizer or air freshener to help mask any smells coming from your tank.
