The three key commodities that are absolutely essential in order to succeed.
We have attempted to provide you with some general rules that apply to all Koi ponds no matter what materials you use in your construction. These are common sense practices which we sometimes tend to overlook.
How Deep Should a Koi Pond be?
A Koi pond needs to be at least 3-feet deep, preferably 4-feet, and in most cases does not have to be over 6-feet deep unless you are trying to grow jumbo show Koi.
In colder climates 4-feet would be the minimum and an area that is 6-feet in part of the pond. In warmer climates you can get away with 3-feet deep, but remember that a shallow pond will heat up and cool quicker, which is not good for the Koi.
Maintenance Planning – Plan ahead
A Koi pond should be as maintenance free as possible, so when planning the location of your bottom drains keep in mind that they will only draw from a radius of 4 to 6 feet. Plan to have enough bottom drains to remove the debris & silt from the bottom of your pond.
Some components to consider
Make sure to install a skimmer and as far away from the waterfall or water return as possible, so that all floating debris to the can flow towards the skimmer.
A vortex, if space and budget allow, is very beneficial for your biological filter, as it will catch the bigger debris and cause less clogging in the bio-filter.
Basic design considerations
The pond edge should always be higher than the surrounding ground to avoid runoff water that could have chemicals from fertilizers, fungicides, and just any debris lying on the ground.
Keep the pond away from trees for two reasons: their roots could damage your pond and you don’t want to have to remove leaves all the time. Leaves in the pond will upset your pond’s water chemistry.
You will want to place the pond in an area close to your house, so that you can enjoy it from inside during inclement weather.
The last consideration is probably the most important, your Budget. This will determine the size of your pond as much as the space you have allocated for it. You should consider everything for the pond—filters, pumps, plumbing, electrical, stonework, landscaping and any other expenses associated with your pond. Once this is done you can begin construction.
