Buying a pond kit can be an easy way to build a koi pond. But you must make sure you choose the right kit. Many of these kits are designed for building garden ponds.
These water pond kits will not be suitable for building a koi pond. They are too small and will be too shallow to make a good home for koi.
Koi are much larger than the goldfish these ponds were designed to accommodate. Koi eat more, poop more and require a much stronger filtration system. Placing them in shallow garden ponds makes them extremely vulnerable to predators also.
Building a Koi Pond Using A Pond Kit
Because the engineering is done for you, by using a koi pond kit it is possible to avoid a lot of the guess work involved in building a koi pond. Your pond pump will work in tandem with your pond skimmer and waterfall making it possible for even someone inexperienced with koi pond design to achieve professional results.
Generally the cost is less to buy a kit than to buy all the items separately. There is also the added convenience of having everything you need on hand and having instructions on pond set up.
Because pond kits make the job easier and the results more certain you can skip hiring a contractor and do the job yourself even if you have little or no construction or pond building experience.
What To Look For In A Pond Kit
First you will want to look at the pond kits size. I would not recommend stocking more than one koi per 500 gallons regardless of your filtration system.
Since koi are big and messy you want the largest kit you can afford. Remember that the 10 inch koi you just bought can reach 36 inches when full-grown.
Once people start raising koi they want to add more fish to their collection so it’s a good idea to think ahead when shopping for pond kits.
Check The Pond Pump
Your pump is the heart and soul of your koi pond. Make sure your pond kit has a well made pump that can turn the water over at least once every two hours.
You actually want to shoot for a pump with higher output than that because it will also be required to run your waterfall. Ideally the pump should be rated to turn the water over once per hour. So if you are building a 6,000 gallon pond with a water fall and skimmer your pond pump’s output should be about 6,000 gallons per hour.
Check The Pond Liner
Make sure the kit contains a quality liner. You want a 45 mil EPDM pond liner. The best liners are made by Firestone. Avoid any pond kits that have a preformed liner as these will be suitable only for use as garden pond kits.
Avoid any pond kits that use anything else but an EPDM liner. Look for pond kits that contain underlayment to protect your liner from sharp stones or other objects. Most good pond kits will come with this.
What Else Pond Kits Include
Besides a good pond pump and the pond liner, koi pond kits will also have a pond skimmer and waterfall unit designed to hold the filter media. Look for signs of sturdy construction. In particular check how easy it is to remove the leaf trap from the skimmer.
Most koi pond kits will contain all the pipe fittings you will need and most will provide properly sized flexible pipe. Various manufactures include different amenities. Some pond kits provide pond starter culture, de-chlorinator, waterfall foam, silicone sealant and even koi food.
For many would be koi pond owners buying koi pond kits can be a great way to break into the koi hobby.
