How To Choose The Correct Pond Pump

Choosing a pump for your pond or fountain is a crucial step to ensure you maintain proper water movement. Failure to keep the water adequately circulated can result in stagnation, algae buildup, and mosquitoes. In addition, if you have fish, plants, or other aquatic life in your pond, you must keep the water healthy by evenly distributing the oxygen levels and other nutrients.

Types of Pond Water Pumps

There are two main types of pond water pumps: submersible and external (out-of-pond), also known as centrifugal pumps. Depending on the application, each pump offers specific advantages.

Submersible Pond Pumps

Submersible pumps are designed to be fully submerged underwater at the deepest part of the pond. They are placed directly into your pond or in a skimmer box or pond vault. Submersible pumps range in size from 50 to 5,000 gallons per hour. They are easy to install and are sometimes a more economical solution for smaller ponds (up to 1000 gallons of water). They are also quiet and can also be used to drain your pond. If you have fish or other aquatic life in your pond, you may want to consider a model that does not use oil because there is a danger of the pump seal breaking and oil coolant leaking into the water.

Centrifugal Pond Pumps

External or centrifugal pond pumps are a reliable, energy-efficient option. They are installed in a dry location near your pond. External pond water pumps are suitable for larger ponds (over 1000 gallons). Compared to a submersible pump, they are typically louder and more complicated to install; however, they are easier to maintain.

When selecting a pond pump, it’s essential to keep in mind that pumps have different cord lengths. Ensure the cord is long enough to go through the pond and plugin far away from the water. Some electrical codes specify that the outlet for water features must be at least 6 feet away from the water. Therefore, it is recommended that you avoid using an extension cord. However, if you must use one, make sure it’s suitable for outdoor use and plugged into a ground fault circuit interrupter (GFCI) so that it will immediately shut off if there is an overload.

How to Size a Fountain or Pond Pump

Pond pumps are sized by gallons per hour (GPH) at one foot of lift or height. Larger capacity pumps are rated by horsepower (HP). To determine the size pond pump, first, you need to calculate the volume of water in the pond. To calculate the volume of water in gallons, multiply the length x width x average depth x 7.5.

Water Circulation Factors

It is recommended that pond water is circulated at least once per hour. For example, if you have a 500-gallon pond, you need a pump that runs 500 gallons per hour at the discharge height. If your pond has a pressurized filter, you ideally want to turn the water approximately once every two hours. For example, if you have a 1000 gallon pond, you need a pond pump rated at a minimum of 500 GPH. If your pond has a skimmer or waterfall, the water should be turned approximately once every hour. Therefore, if you have an 1800 gallon pond, you will need an 1800 GPH rated pump.

Calculating Head and Lift Height

Two of the most critical measurements in sizing a pond or fountain pump are the maximum head height rating and maximum lift. Head height means the vertical height the pump raises water above the surface of the pond. The pond fountain pump’s top height can lift the water to is called “Maximum Head” or “Max Head.” The “Head” is measured straight up from the water level of the pond. Its length then measures any horizontal/diagonal flow, and 1’ of “Head” added per 10’ of horizontal/diagonal distance. To calculate the lift, you need to measure how far the water in your fountain has to travel from the pump’s location in your rush to the top of the fountain where the water comes out. Then you need to select a pump that lifts higher than that measurement. For example, if that distance is 24”, than you will need a fountain pump that lifts at least 36” tall. The “maximum lift” is the maximum height that the pump will raise the water.

Selecting the Proper Pond Water Pump Tubing

It is also essential to use the correct tubing size because it directly affects the pond pump’s maximum lift capability. If you use smaller tubing than specified, you will limit the pump’s maximum lift and the amount of water circulated.

Choosing the right pond water pump for your pond or fountain requires careful consideration and a little upfront research. However, doing so will go a long way toward keeping your water clean and healthy and your pump operating efficiently.

Best way to Maintain Water Features in Garden

Having water features in your garden, whether small or large, gives an utmost sense of calm and tranquillity. To keep these water features as smooth as possible for a long time, it’s essential to regularly maintain water features in garden like pond, waterfall, fountain.

Water Filters:

Water filters are an essential component of a healthy pond ecosystem. Filters help to process fish waste, uneaten fish food, leaves, and runoff from lawns. It is recommended to choose the right filter right before you start building the water features. If the water features are already built, it is difficult to add a skimmer or bio falls. In such a case, a submersible pond filter can be used. You can check some of our filter products here.

Water cleansing:

If the water is dark in colour, there is a chance that there is a crud at the pond’s bottom. In such a scenario, it is better to do a full-scale cleaning of the pond water. Empty the pond water into the surrounding landscape. With the help of a garden hose, rinse the rocks and gravel. Once the pond is cleaned, you can remove the water pump and fill the pond again.

Plants trimming

Skim and trim the leaves and plants in the garden every week. This helps to keep debris to a minimum. Control the spread of algae. Floating plants limit sunlight allowing to check the growth of algae. Additives can also be used to reduce algae growth.

Regular checks

Conducting regular checks on equipment like pumps and filters to ensure they are free of clogs and debris helps them operate properly. Test the water regularly, especially if you have fish, as excessive amounts of chemicals like ammonia and chlorine can affect their health.

Keep the water moving.

Circulating the water with a pump, waterfall, or fountain will help avoid mosquito larvae from hatching to maintain water hygiene. Moving water also helps to distribute and support the oxygen levels throughout the pond for fish. Install features like small waterfalls or streams which help to keep the circulation of water. For proper circulation, choose the right kind of pump for your pond. We have different collections of water pumps which you can choose from with the help of our experts.

Seasonal pond care

Fluctuations in seasons require different maintenance of ponds. What you do with your pond during this seasonal transition depends mostly on where you live. If your area experiences long periods of freezing weather, you may consider shutting down the water flow or adding a floating de-icer. You can choose to keep water running, but do ensure that an ice dam does not form. Here are a few products to consider, as you plan for seasonal pond care going into the fall and winter months.

Following the above recommendations can easily help you maintain water features in your garden.

Koi Carps

In the last few years, keeping Koi Carps in ponds has been a trend. These fishes are native to Japan and hence are also called Japanese Koi. Koi comes in different vibrant colours and may grow up to quite a large size of 28 to 32 inches. These fishes require constant temperature in water and need water to be fresh. They can live a long life by pond fish standards, with some living up to 40 years old. If you are going to keep koi, you need to have a larger pond with 50 to 60 inches in depth.

These are just some of the varieties of pond fish, and there are many more still. Whatever pond fish you choose as part of your garden pond, always remember, taking proper care of fish and ensuring adequate living conditions and diet is most important.

Tips for building a great Garden Pond


A garden pond could be a part of a larger waterfall mechanism in a garden or a simple fish pond. There are certain things to be considered while building a garden pond. A nicely build garden pond will add liveliness and beauty to a garden. Below are some tips for building that perfect garden pond.

water garden installation and construction

Keep the pond size suitable
It makes sense to build a pond of a size which will ultimately suit the garden. A pond of very small size or one which is too big won’t be suitable. Also, the location of the pond in garden with respect to house should be considered. Take the opinions of some friends or neighbors to see what would be a suitable location and size for the pond. Planning the size of the pond is extremely important before starting the building work.

Protect the bottom of the pond
It’s essential to protect the bottom surface of the pond against burrowing animals. To protect your pond, make sure to lay down a metal sheet on the surface and then lay dirt and mud on it. Then place the underlayment and liner on top of the dirt. Make sure to protect the sides with pond lining as well to prevent the water from getting out.

Plan the drainage carefully
It’s a high chance that your pond will overflow, especially in a rainy climate. To avoid water spilling out and damaging the plants or area of lawn outside, identify a spillover area in your garden and implement it. Then channel the water towards the spillover area.

Filling the pond
Be creative and fill the pond with great care. You can use a garden hose to fill in the water only up to a certain level. Add in different types of rocks and rounded stones. You can also add different fishes and plants, and amphibians like small turtles to the pond. While adding fishes and other animals and plants, care should be taken to not add species that are invasive or predatory on each other.

Cleaning the Pond
Garden ponds will collect leaves, dust, debris, and you will have to eventually clean it. Create a pond with a smoother surface and lesser rocks, which will be easier to clean. The cleaning process takes a lot of time and planning should be done while building the pond about how much time one would like to spend on cleaning and pond maintenance going ahead.
