Can you use a timer on a koi pond to save on energy costs?
Well, it depends.
If you have a larger koi pond with multiple streams or pumps, then yes, you could shut them all down except one pump that meets the minimum required circulation.
If you only have one pump on your pond, then no, do not use a timer. Your pond and fish and plants need to breath. Your pump is the source of that oxygenated water.
Now pondless waterfalls and fountains are not necessarily maintaining a living ecosystem, so you can put those on a timer as much as you wish.
Keep in mind, your pond is a living, breathing ecosystem that needs constant oxygen, just like the human race. If you shut your system down at night, then you can never have sufficient growth of beneficial bacteria to fight algae blooms, and your finned friends will have a hard time breathing.
