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.
Selecting a Correct Pump For Your Garden Water Features
Water pumps are one of the most crucial features of the garden pond. Although a static garden pond pump isn’t an absolute necessity, a pump is required when we install a fountain, waterfall, and filter. A water pump helps to keep the circulation of water. Water circulation helps to keep the fish and plants healthy. Water circulation helps in the prevention of algae build-up, breeding of mosquitoes, and stagnation of water. Water circulation also helps in the proper distribution of oxygen levels throughout the garden pond system.
Choosing the correct pump can be difficult, but it doesn’t have to be!
For a heavy waterfall flow, you’ll want to use about 2,000gph per single foot of waterfall discharge. If you would like a lighter waterfall flow, use about 1,000gph per foot of waterfall discharge.
Take note of your tubing from the pump to the waterfall. If its greater than 10′ then we recommend to add about 1 foot of head for every 10′ of tubing.
First you will want to determine the head pressure. Head is the same as the total number of feet from the top of the waterfall to the top of the water’s surface.
Second, you’ll want to determine the desired water flow. How much water do you want moving over the waterfall per hour? Usually you’ll want about 1,500 gallons of water per hour (GPH) for every 1 foot of waterfall discharge. This is just the average though, you may want more. For instance, if your waterfall is 2′ you’ll want a 3000gph pump.
Lastly, in this example the head pressure is 5′ and the estimated pump needed is 3000gph. Noting this information, we find out that we will need a pump that is 3000gph at 5′ of head.
Aquascape pond pumps can be tricky if you’re uncertain what you need. The simplest solution is to give us a call and ask what size you need for your water garden, but beyond that, take a look at a pump calculator to see which one you need. Simply add in the values for your water garden and you’ll be able to find out exactly which pond pump you need.

Solar Powered Water Features for the Garden
Nothing can complement water more than a lovely beautiful sunlight. Water along with sunlight is what really makes up a beautiful summer day. Ancient water features were powered using gravitational forces, human power or animals to pump in the water. Since the 18th century, the majority of water features have been powered by pumps. In the modern garden features the source of power is almost always electricity. As more and more people become aware of alternate installation methods, there is an increasing range of innovative designs in market running on alterante sources of energy like solar power. The advantages of using solar power include environmental benefits, no electrical lines in the garden, and free energy.
Solar water features combine the beauty of sunlight and water by using the sun to run their submersible pumps, which send water tumbling downward to the basin and back up to the top again. The same natural looking resilient materials used to make other regular fountains are used to build these solar powered water features, however, these water come without the ugly looking cables. One of the biggest advantages of using solar powered water features is there is no cost on electricity as sun being a natural resource. A Solar with Battery Backup fountain even includes a battery to save up energy for nights and cloudy days.
Solar water features free from the electrical cords present a great amount of flexibility in regards to their placement in garden as they are no longer limited due to constraints of wires and cables. These solar powered water features help you in making your little bit of contribution towards the environment. With solar powered water features in your backyard garden your outdoor space will truly be one with nature.
Solar water features provide beautiful additions to any landscaping or garden. With great flexibility offered by solar water features, you can customize the placement of water features in many ways. You can choose from a plethora of water features such as solar powered fountains, waterfalls, lightning. All of these run on pure solar energy thanks to solar panels and help to add beauty to your garden.
