The Best Pumps for Koi and Fish Ponds

If you have a koi or a fish pond, their safety is likely at the forefront of your mind when it comes to choosing a pump. If it’s not, it should be! Koi and fish are an excellent addition to any pond and are great for helping you achieve that peaceful aesthetic you may want.

Choosing a pond pump for their safety is actually a lot more important than you might think. A pond pump that’s the right size helps to circulate the water and oxygen, as well maintain the water clarity you need.
