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.
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.
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.
Fish Friends for Koi
Fish Friends for Koi
When they are in the wild, Koi live with other species of carp. Koi also get along well with killifish and minnows.
Other types of fish that can be found in the lakes and streams they inhabit are large game fish, such as perch, bass and Catfish.
Koi are peaceful and do not bother or prey on other fish in your pond which makes it great for stocking your pond with a variety of other fish.
Sunfish get along well next to carp with Redear sunfish being the most popular for a carp pond.
Grass carp act as natural pruning system for your pond and they will make great friends for your Koi. Grass carp will also help maintain your plant vegetation as they like to eat and out of control plants that are growing too big.
Since they are similar, goldfish make a great friend for your Koi. They share similar color patterns to Koi and will help compliment the beauty of your precious Koi in their new garden pond.
For other fish, largemouth bass, catfish and striped bass will make perfect mates for your Koi. Bigger fish will require a larger pond size so keep this in mind when selecting the size of your garden pond.
Frogs can be really good friends for your Koi or any kind of amphibian. Local frogs, newts and even salamanders can share the same space as your Koi with no issues.
Try to attract frogs naturally to your pond rather than stocking them from a store. Frogs from pet shops may have bacterial infections or diseases that can spread to your fish. We want to keep your fish as healthy as possible so they can live a long life in your garden pond.
Fish that you want to avoid stocking your garden pond with if you have Koi are Bluegill. Carp and Bluegill are rivals and will be destructive to your garden pond as they compete for resources and food.
Small fish such as nano fish should be avoided too. These smaller fish will not be happy swimming around with large Koi and will be anxious and nervous when in an enclosed garden pond with them.
Lastly, the best option to stock your Koi pond with is more Koi. They like to be in a group or a school and the minimum for that is at least 5. If you have a larger pond, you may be able to accommodate up to 15 individual Koi. Be sure to consult with our professionals about the needs for your Koi pond setup.

Koi Pond Setup
Pond Setup for Koi
Koi are the more sophisticated version of their wild versions which are common carp. Carp are traditionally native to Europe and Asia.
The habitat of carp are lakes, streams and ponds with mud near the bottom and minimal water flow. They can be found in temperate and tropical areas and they like water temperatures over 70 degrees F.
Carp are most active in the dim lit hours near dusk and dawn but they will forage for food at all times of day.
Achieving these living conditions for your new Koi is not a hard task.
Koi Pond Setup
Koi prefer temperatures between 74 to 86 degress F year-round. For areas where it is colder, a heater system will keep them from freezing and protect your valuable fish.
A small stream or waterfall is fine for your Koi but they do not require an water flow to be happy.
For the pH of your pond water, it should be kept between 6 and 9. Crushed limestone can be used to help maintain the pH levels in your garden pond.
For best results, a Koi pond with concrete and rubber lining are best. For the bottom of the pond, a substrate that mimics a mud consistency will have your Koi feeling right at home.
A beautiful outdoor water garden will give the best result for a pond setup. The plants should be non-invasive so they don’t damage the natural ecosystem for your new Koi friends.
The best plants for your water garden will included:
* pickerels
* floating pondweed
* water lilies
* cattails
* water hyacinth
* duckweed and more
Willows and other shade trailing trees around your water garden pond are recommended by other garden pond owners. These will help to provide extra shade and cover for your fish.
How big should your Koi pond be?
250 gallons of water is the minimum for keeping a Koi in a pond. A school of Koi may require over 1000 gallons of water.
Ten gallons of water is needed for every inch of fully grown Koi as a rule of thumb. This same rule can be applied to other fish as well. Because Koi can reach 3 feet in length, this means that 250 gallons is the absolute minimum for one adult.
