Components of a Koi Pond: Backyard Pond Kits


Components of a Koi Pond and Backyard Pond Kits.

So you want to build a Koi pond and are in search of backyard pond kits. Consider what season you're in.

If you're in the late fall season or even winter months, we suggest picking up in the spring.

With so many options available, all you need is a push in one direction. Keep in mind that once your Koi Pond is complete, your work is not done until you're ready to winterize the pond in the coming months!

Here, we will discuss the important components of a Koi Pond and what you might find in your Backyard Pond Kits.

The Underlay of a Koi Pond

The underlay of a Koi pond is a thick filter cloth material is used under liner for protection. It also be used on top of liner under larger rockery.

It must be installed during pond construction.

Koi Pond Liner

EPDM Liner (45 mil) is used to line the pond and behind the falls/stream. This liner is flexible and durable. It must be installed during pond construction.

PVC Flex Pipe for Koi Ponds

PVC Flex pipe is used to connect pumps to filtration then to the spillway. PVC flex pipe is durable and flexible.

PVC fittings are used in pond construction for durability to withstand sunlight and freezing.

PVC glue and primer fuse the fitting to the pipe. It must be installed during pond construction.

Pond Spillway or Up-Flow Filter

An up-flow filter or spillway is used at the top of the falls or stream to diffuse the water and provide even falls.

This filter will also provide and additional filtration pathway once filled with Pond biological materials or, Pond Bio Media.

It must be installed during pond construction.

Koi Pond Skimmers

A pond skimmer using a skimmer pump, draws the surface water into a basket or net to keep the surface clear of debris ie. leaves, dirt, unwanted animals.

It must be installed during pond construction.

Skimmer Pump for Koi Ponds

A pond skimmer pump is a submersible pump that is placed within the skimmer to draw in the surface water and circulate it back up to the spillway.

It must be installed during pond construction.

Pressurized Filter with UV For Your Koi Pond

A pressurized pond filter cuts down on much of the manual cleaning of the pond.

A solid handling pump at the bottom of the pond feeds the bottom water (sludge and debris) into the pressurized filter.

The pressurized filter has a backwash system that cleans itself with a few pumps of a handle.

A UV system is often incorporated into a pressurized filter to keep the water clear of suspended algae (green water).

It can be added during construction or after construction- it’s reported to be easier to add during construction.

Solids Handling Pump

A solids handling pump for your koi pond construction can handle small debris and sludge and therefore is placed at the bottom of the pond.

The pump feeds the debris and sludge into the pressurized filter and back up to the spillway or directly back into the pond.

It can be added during construction or after construction- it’s reported to be easier to add during construction.

Pond Aerator

Pond aerators systems act by oxygenating the pond water. Every process in your pond depends on oxygen.

Oxygen levels drop in higher heat and at night; this is why supplemental aeration is required.

Pond aerators also provide oxygen in the winter months.

A great way to save energy by turning your waterfall off at night, allow your aerator to oxygenate!

The pond aerator can be added during construction or after construction.

Pond Ionizer

A pond ionizer releases ions into the water through a probe which is placed in the pipe line, in the skimmer or in a stream.

An ionizer is the only mechanism that can control/eliminate string algae. The pond ionizer can be added during construction or after construction.

Float Valve or Electronic Water Level Controller for Your Pond

A float valve or electronic water level controller maintains a constant water level in your pond. It easily connects to a ½” water supply line.

These units ensure your pond water never drops too low.

Often installed into skimmers.

The Float Valve can be added during construction or after construction.

Additional UV For Your Pond

Additional UV filters may be needed in a pond if water clarity is lacking.

A UV sterilizer/clarifier can be added in-line anywhere from the skimmer pump to the spillway.

Can be added during construction or after construction.

Pond Lighting

Pond lighting can be used in or out of water. Pond lighting allows you to view your pond at night when most people are home or entertaining.

Simple yet beautiful, the pond lighting of your choice can be added during construction or after construction.

Pond Deicer

A pond deicer is a unit used to create a small hole in the surface of your pond during the winter months and insures proper gas exchange to keep the fish alive through the winter.

These units are thermostatically controlled, making them cost effective.

The pond deicer must be added during the winter.

When to add Pond Fish?

Either pond fish or koi can be kept in a pond. If you are looking to over-winter your fish a pond, ensure one part of the pond is 4 feet deep for the fish to go dormant in.

A pond deicer and aerator should be used in the winter.

Let new pond run for at least a week with beneficial bacteria and plants before adding fish. Use a dechlorinator.

Pond Plants as a Finishing Touch

Plants provide the necessary shade and hidden cover for fish.

They provide oxygen during daylight hours and filtration. Plants are used for decorative purposes to provide a more natural look to any pond.

Add pond plants to pond only once the water temperature has become equal to what the plants were accustomed to.
