Outdoor Koi Pond
You were mesmerized by the brilliance of the colorful koi at the fish farm. You have a strong desire to complete the small patch of vacant land in your back yard. Now learn how to make your new found koi into the most comfortable, safe, and cared-for fish in the world.
Let’s take about building a good habitat for the koi fishes. There are a couple ways you can make an outdoor pond. One is to take a swimming pool that is not used very much and change it into a koi pond. This is easy for the koi owner to do. It would probably look nicer, though, if you paint it a darker color so you can actually see your koi. You will also need to change your pool’s filter into a biological filter.
Another way to make a koi pond is to build your own. To do this, you will need to dig a hole that is at least three feet deep and deeper in colder regions. Once the hole is dug, you will need to line it with some kind of plastic liner. You want to cover the bottom with gravel and make sure the sides of the pond are straight up and down to discourage predators.
Besides the actual koi pond rocks structure, you will need a pump and a biological filter. To conserve energy, you either want to purchase a high head pump or a low head pump. For smaller ponds, a submersible pump would be a good choice. These are easy to use and work pretty well at running a filter.
Depends where you live and what climate you live in, it’s important to consider the needs to control koi pond temperature. Obviously, Koi ponds in cold or hot geographical regions will need to be handled differently.
Having a good koi pond filtration system is essential to having healthy fish and clean, clear water. Bio filters get rid of fish waste that the fish release from their gills. Koi bio filters come with either an up flow or a down flow. An out of pond design is easier to deal with and can be added to a pond that is already built. The best spot to pick up your filtration system is your local koi dealer. Check out their ponds and see what they do. Ask questions and get advice on what works.
Besides an effective filtration system, you will need decent testing kits to test the water quality in your pond. When you test your water, you will be concerned with pH levels, ammonia levels and nitrite levels. Optimal pH levels suitable for a variety of koi fish are between 7.5 and 8.2. pH measures how acidic or alkaline a liquid is. Ammonia levels are important to monitor because this chemical is very toxic to koi fish. Ammonia is produced as a byproduct when fish eliminate wastes into the water. These levels should be kept as close to zero as possible.
Nitrites are a byproduct of ammonia, and while not harmful immediately, they will eventually break down a fish’s immune system and starve them of oxygen. The levels of nitrites should also be kept to a minimum. One way of neutralizing the effect of nitrites is to add a salt solution to the pond. This helps the fish build up a resistance to the harmful effects of nitrites. Adding suitable koi pond plants may also help in controlling the nitrites level naturally.
