It’s difficult to imagine that there are people who disapprove of water ponds or who think they do not add something special to a garden. One’s mind immediately conjures up a picture of a pleasant sunny day, a verdant lawn, a deck chair and a tranquil pond, its surface still as it mirrors a blue sky. Who wouldn’t want one?
Ponds need maintenance to ensure that they remain a healthy place should they be home to aquatic plants or fish or to the types of amphibians which occupy gardens or farms and also to avoid the water becoming stagnant and malodorous. This can be achieved through the installation of a water pump which creates movement through the water.
As is always the case these days, there are myriad choices when it comes to buying a pond pump. We’re here to make that choice easier under a range of categories and criteria. Here goes…

A Guide to Water Pumps
Without movement, stagnation will set in with its attendant problems – insects of the unwanted variety (mosquitoes, midges, etc.) and weeds which are both unattractive and invasive. Over time, the water will become home to algae and a scum replaces that once pristine blue sky-reflecting surface.
Movement within the water ensures oxygenation and aeration which is essential for any fish which inhabit the pond: devoid of such circulation, fish will perish due to toxins forming. Aerated water will also attract the sort of insects who are welcome from an ecological perspective.
Now that we’ve established that a water pump is necessary, let’s look at what should be considered before purchasing one.
Types of Pumps
There are two universally recognized types of pumps: submersible (inserted directly into the water) or external (also known as out-of-pool or surface pumps).
Submersible pumps have the aesthetic advantage of being invisible and usually less expensive to install and maintain. They do not require any protective covering outside the pond and tend to be quieter than external pumps. Due to their positioning, however, they’re more prone to clogging.
External pumps are located out of the pond and are, of course, visible. If there is a desire to keep the external pump out-of-view, it can be hidden in shrubbery or placed under cover. The latter option will help protect the mechanism.
When making a choice, one needs to factor in poll size (and its occupants) since pumps are measured by the amount of water circulated using GPH (gallons per hour) as the standard measurement.
Submersible pumps are viewed as the best option for smaller ponds (less than 1,000 gallons) whereas external pumps are favored for ponds in excess of that capacity. In a natural pond (devoid of fish), the accepted criterion is that all the water should be circulated every two hours e.g. a pond holding 1,000 gallons needs a pump with 500 GPH capacity.
The equation changes if the pond is populated. If it’s a goldfish poll, the water should be circulated every 1.5 hours. Since goldfish are small creatures, such ponds also tend to be smaller. If the pond is home to Koi, there will typically be a larger population and the water must be circulated every hour to combat the build-up of toxins and debris. This means a more powerful pump is required since filtration uses half of the pump’s power.
Below is a guide to poll/pump size ratio:
|Pond size (gallons (GPH)||Recommended Pump Size|
It should also be noted that the depth of the poll should be twice the height of the pump to prevent a water vortex forming. Such an occurrence sucks air into the pump and adversely affects its performance.
The Economics of Pump Selection
Pond pumps have running costs which should be factored into the choice of product. With ever-increasing energy costs, a pump running all day every day will rack up utility charges so energy-saving models should be considered. There may be an increased initial outlay but that can eventually be recouped through reduced electricity and water bills. Solar-powered models are now on the market and have become increasingly popular in these environmentally aware times.
Matching Features to Available Choices
A pond may incorporate special features such as a stream, waterfall, fountain, resident fish or other forms of aquiculture which must be considered. Equally, pumps have varying abilities and features. Some work better with waterfalls, others are more adept at oxygenating the water. A thorough appraisal of these capabilities will allow the consumer to make the optimum choice. Time spent on this selection procedure will be rewarded.
