Smelly pond

Question:

My water feature water smells after not being used can I add anything to the water to stop it smelling?


Answer:

If it has no plants or fish in it, use swimming pool chlorine to clean it up. If it is a pond with plants and fish, start the pump, add submerged and floating vegetation. Pump out 25% of the water and replace it. Don't forget to add dechlor.
