Koi Ponds: Basic Information You Should Know

Advertisements

Here are some important points to consider for your koi pond, when designing and considering constructing a Japanese koi pond for yourself or with the help of professional koi fish pond builders.

Koi Pond Size & Maintenance

While it is said that for the size of a koi pond, that the larger the better, if a pond size is extremely large, then maintenance and cost then becomes an issue. This means the total cost of upkeep of the pond including pump costs and replacements, any water treatments required, and electrical costs, as well as the ability to monitor the wellbeing of your fish and being able to net your fish out when required.

For example, a koi pond larger than 20 by 12 feet, according to Eric W Poingdestre [1] becomes difficult to manage.

It depends on the resources you have for your koi fish care and maintenance.

Pond Depth

According to most koi experts, your pond depth should be 6 feet. If you have a smaller pond, the bare minimum you can go as low as 4 and ½ or 5 feet, but the slightly deeper depth is better. The more shallow depth of 4 and ½ feet have been used in cold climates but the concern here is survival of the fish during the very cold weather where freezing over can occur.

Japanese Koi Pond Construction

Because koi ponds require digging out part of the garden, it's a job that requires the help of people, whether you’re going to build a koi pond yourself, or hire professional.

But also, you’ll need sound advice and information from your builder and council that there are no major plumbing or electrical lines in the area where you’re intending to dig and build.

Also consider your koi pond liners. The lining of the pond is usually in the form of a butyl liner or fibreglass. Butyl liners can be attempted by hobbyists, but fibreglass construction is by the experts. With any material check to see that it is safe for koi, as there are many different brands of liners, to ensure that they are not toxic to the pond environments and the koi.

Koi Pond Design

Be aware that a well designed koi fish pond will help with proper maintenance of your koi fish.

A sloped bottom that leads to the bottom drains helps with drainage.

Vertical walls increases volume of pond as well as reducing the chances of predators getting to the fish.

If you’re using a plastic lining, then you’ll want to avoid sharp folds and corners to prevent breakage of the lining.

There are many good koi designs available, and whichever you choose and modify, always ensure that you know the actual volume in your pond both in the design as well as during construction (in case this changes). This is so that you can accurately calculate the amount of product to use as water treatments if needed in future.

Before considering a koi pond for the garden, always remember the safety aspects.

If you have small children or you have small children as neighbors who have access to your yard, then koi ponds may not be a safe option.

So have a careful look at your garden, and consider each of these points when looking at and choosing a good koi pond design.

Have a look also at what koi pond supplies you'll need for a new or existing pond.
