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.
Can You Use an Air Compressor to Aerate Ponds?
Can You Use an Air Compressor to Aerate Ponds?
If your pond needs aeration, you can turn to an air compressor to get the job done. Air compressors intended for use in water, however, differ from those manufactured for use on land, and many kinds of compressors exist. Before choosing one, figure out your specific goals for pond aeration, which will make choosing easier.
Land vs. Water Use
Although the term “air compressor” sounds like the machine should be able to deliver high volumes of pressurized air to any medium, that isn’t the case. Many air compressors are intended specifically for use in dry conditions — for instance, to power tools — and won’t function in water. Also, air compressors not intended for aquatic use can contribute toxins to water. Even when the word “pump” is part of an air compressor model’s name or label, the compressor still may not be suitable for pond use. That is because although “pump” usually indicates an item can be used with liquid systems such as ponds, some air compressor pumps are meant for use on only land.
Aquatic Air Compressors
All air compressors used in ponds should be “oil-less” because, compared to their counterparts, they deliver higher quality, cleaner air, which is safer for the animals and plants, or aquaculture, in the pond water. Aquatic air compressors are more high-tech because they can move oxygen through water without breaking stratification, which means they won’t mix the warm upper and cold lower pond water layers. Air compressors usually are intended for use in large ponds deeper than 8 feet. So if your pond is shallower, you could consider other aeration methods.
Other Aerators
Blowers, diffusers, pumps and fountains can achieve satisfactory pond aeration. Blowers work well for shallow ponds and often are used in conjunction with air diffusers, which mix pond water, breaking stratification. Surface aerators force water from about 6 feet down upward to snag oxygen from the air. Fountains achieve the same effect, often with decorative flair, making them an option for aerating small, shallow garden ponds.
Aeration Benefits
Pond aeration provides many benefits to aquatic ecosystems. Adding oxygen to a pond through aeration is often necessary when algae blooms deplete it or when it is treated chemically for plant overpopulation; the addition of oxygen helps pond fish and other aquatic species stay alive during those times. Aeration also circulates pond water, preventing problems such as stagnation, mosquito breeding and the debris buildup that often accompanies low oxygen levels.
Benefits of Having a Garden Pond
Having a garden pond is a dream for many homeowners. While creating a garden pond ecosystem can be a lot of work, there are many long-term benefits of building one. A garden pond provides aesthetic beauty to your house or commercial premises and can help you impress your neighbors and visitors. Below are some of the benefits of building a garden pond.
Natural Calmness and Beauty
A garden pond ecosystem provides a natural scenic beauty and natural calmness to your garden. It acts as a relaxing retreat from all the busy work life worries. Having a garden pond provides a very positive effect on the mind and body. Spending some time amidst your garden pond ecosystem can rejuvenate your mind and increase focus, creativity, and sleep quality, reducing stress and anxiety. Having a positive effect on the mind will also improve physical health.
Less pollution
Garden equipment machinery emits high levels of carbon monoxide, volatile organic compounds, and nitrogen oxides. When a pond occupies space in your garden, it automatically reduces the space available for plants and grass. This leads to less use of lawnmowers and garden equipment machines, leading to lesser production of gas and other air pollutants. It also helps in reducing the use of pesticides and fertilizers. Reduced usage of fertilizers helps to reduce the levels of toxicity in the garden. It also leads to cost savings on garden machinery and fertilizers.
Safe sanctuary for local wildlife
While ponds can be filled with beautiful fish, such as Koi and goldfish, they also attract and provide a sanctuary for local wildlife. Aquatic plants can be grown in ponds, which can attract different types of birds and frogs. The growth of algae also attracts tadpoles and other small aquatic animals. A garden pond can lead to an entire ecosystem of flora and fauna of local plants, birds, and small animals.
Financial benefits
We already discussed building a garden pond to save costs on garden machinery and fertilizers, and pesticides. But the most significant financial benefit of having a garden pond is it can help increase the overall value of your property. A garden pond makes your property far more attractive to prospective buyers. Having an already present garden pond means your potential buyer will have to spend money to build a new one, plus it gives your property that premium feels and helps command a larger price.

Water Pumps for your Garden Pond
Water Pumps for your Garden Pond
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 a correct pump for your garden pond is very essential.
There are following types of pumps for Garden pond
Submersible Pond Pumps
These pumps are fully submerged under water normally at the deepest area of the pond. They are a very economical solution for a small size pond and make a perfect fit for garden ponds. Submersible pumps are excellent for ponds with fish as all the electrical parts are well isolated from water, thus reducing the risk of oil spill or an electrical accident. The water intake pipe attached to filter helps to clean the water before it is delivered to the pool by the outlet pipe. These pumps come in many different sizes.
External or Centrifugal Pond Pumps
These pumps are installed outside the pond usually in a dry location. They are easier to maintain. These pumps are suitable for larger ponds. Compared to submersible pumps they do make a lot of noise.
Selecting the right pump for your Garden Pond
Garden pond pumps are measured by Gallons Per Hour. It’s recommended that the pond water is circulated every hour. So, if you have a pond with a water volume of 1800 gallons then you would require a pump with 1800 Gallons Per Hour. However, if your pond has fish and other aquatic animals you may have to select a larger pump with a capacity at least twice the volume of water in the garden pond.
Choosing the right kind of pump for your garden pond will help to keep your pond clean and healthy. We at Aquascapes can help you to select a pump that’s the right fit for your Garden pond needs with our expertise and experience. You can also check various water pump products in our catalog here.
