Comparing Garden Pumps for Your Pond Projects

A garden pond needs healthy water. No one wants to sit and look out over a green, stagnant ooze while being munched on by mosquitos!

When comparing garden pumps, you need to know which is most likely to be the best one to keep your pond running smoothly. This means proper water circulation and equally distributed oxygen levels, especially if you have fish or plants.

Submersible vs Non-submersible

But how do you know what is the best pump for your pond? There are two main options when it comes to pumps. Let’s look at some comparisons between the two

Submersible Garden Pumps Non-submersible Garden Pumps
●      Designed to be fully underwater ●      Need to be installed in a dry spot near the pond
●      Economical for small ponds up to 1000 gallons ●      A better option for large ponds over 1000 gallons
●      Run quietly and are easier to install but require maintenance ●      Run louder and require more installation work, but are easier to maintain

 

How to Calculate for a Pump

Now that you know a bit more about the two garden pumps available, it will be easier to decide on the right pump for you. But if you moved into the house and the pond was already there, or if it was a spur of the moment DIY project without too many measurements, how do you know what size your pond is?

To find out what size pump you are going to need, there is a simple calculation to work out the volume of water in your pond (all measurements done in feet):

Pond length x pond width x pond average depth x 7.5 = water volume in gallons

Water Circulation

Ideally, you want your pond to circulate the water a minimum of once an hour. So, if you have a 500-gallon pond, for example, you will want a pump that is rated at a minimum of 500 GPH.
