Koi Fish Health

Keeping your Koi Fish healthy takes careful preparation and planning. There are several major factors to look out for.

Poor Water Quality

Poor water quality is the leading cause of koi-ulcer Koi Fish deaths and Koi Fish Ulcers. Just like humans are concerned with the quality of the air that they breathe, fish need that same quality in water. Keeping a steady pH is crucial. Even if you are in the parameters of a healthy pH (6.8 – 8.2), it still shouldn’t change much, as a sudden change can shock the fish, causing severe stress, or possible death (similar to living in extremely clean air, and then moving to a smokey, humid room).

Another major problem is if a Koi Fish is not getting enough oxygen. If oxygen levels decrease, all fish in a pond can potentially die overnight! Keeping an eye on oxygen levels is crucial. Remember, if you add more fish, you are going to need more oxygen. Changing out water is very important, but remember not to change all of the water at once. It is suggested to change between 25% and 33% of a pond at a time. Any more can shock the fish causing stress, or death. If you live in a climate where the pond is going to freeze, you must remember to expose areas of the surface to allow for gas exchange, and prevent toxic buildup. A great device to maintain oxygen is an aeration device, which disturbs the water constantly, similar to a waterfall.

Parasites

The second leading cause in Koi Fish deaths are parasites. The leading cause of parasite contraction is through other fish. It is a good practice to quarantine a fish for a few weeks before introducing it to your pond. Although this wont ensure that the fish is parasite-free, it is a strong indicator that it is, and if it isn’t, that the amount of parasites on the fish isn’t reproducing fast enough to harm the fish, or it’s environment. When purchasing a fish, it is always good to ask where the fish is from, what treatments they use to keep their fish parasite-free.

Parasites generally congregate on the sides of the fish, top of the head, and along the base of the tail. The two common parasites that are visible without a microscope are anchor worms, and fish lice.

Fish Lice are about a 1/4 inch in length, and are green, fish-lice translucent, jelly like creatures. They have several sets of legs that are used to attach to the Koi Fish. To treat, you need to purchase Fluke tabs, or ProForm LA. Assuming that your water doens't need Oxygen, pH or other treatments, you should have no problem ridding your fish of Fish Lice.

Anchor Worms are not actually worms, but copepods. The anchor_worm female will attach her head to the fish by using its head, which is shaped like an anchor. The male worm attaches itself to the female, and fertilizes her eggs. After the eggs are released, the worms die off, leaving open wounds on the fish. These wounds can easily turn into infection. There are several treatments including Fluke tabs that will work, but the most effective way to rid your fish of anchor worms is to qurentine them, and manually remove the worms with tweezers.

Fish Stress

An unhealthy fish is an unhappy fish. Not providing the proper elements to resemble a natural habitat can cause serious stress on a fish. It is important to have the correct plants. Having plants that offer oxygen, food, and shade are crucial. If a fish doesn’t have proper shade, they will stress due to heat. Also, if the water is cooler, than it can hold more oxygen.

Lack of Sunlight

Another common problem is adding too many plants to your whitekoi pond. Although fish like to hide from the sun when it is too hot, having a pond that has too many plants can cause your fish to not get enough sunlight. This is an easy problem to spot and fix. If you have a colored fish that is losing color, it is possible that they have a lack of pigment which can be caused by a lack of sunlight. The easy fix, is to remove some of the plants from your pond. Don't remove all plants, as the fish do need a place to escape from sunlight on bright, hot days, but remove some of them.

Bulging Eyes

If a Koi Fish's eyes start to bulge, a number of causes are koieyebulge_copy possible. The reason that a fish's eyes bulge, is due to fluid buildup either behind the eye, or actually in the eye itself. The most common cause is due to bacteria. If a fish is introduced to the pool, it could be related to stress. It is best to quarentine the fish and look for signs of improvement. Another common behavior is lack of appetite. If your fish stop eating, it cold be due to bacteria in the water. The best remedy is to start to change out water. Over time the fish's eyes should start to retract, and appetites should resume. If not treated in time, the fish's eyes could have to be removed.

Excavation

The Excavation process is the ‘ground breaking’ step. First you mark off your perimeter with paint marks. From there you will need to start excavating the dirt. Depending on the size of your Koi pond, generally a backhoe, bobcat, or shovel(s) are used. If you are going to rent machinery, be aware that the more time it takes, the more money it will cost. If you are hiring an excavation company to do your work for you, don’t be afraid of big companies. Although the smaller, more localized companies are great, what it really comes down to is experience. Ask as many questions as possible. See how long the company has been in business, how large the company is, and how many ponds they have dug. Search for reviews online at places like Yelp. One potential problem that is frequently overlooked is access to your pond. If you are bringing in heavy machinery, you always want a clear path from the road. Many times...

Preconditioning

Pressure Wash After all cleanup has been taken care of, you will want to pressure wash your pool. This will help to remove all dirt, and cement film left behind. A thin layer of dried cement will be left behind, called ‘surface cement’. Be sure to spray all cracks between lights and other fixtures. Acid Wash Before you fill your pool, you will want to give it an acid wash. The reason for doing this is to wash away any leftover grit, dust, and other debris left from the cement. For the acid wash, you will need diluted Muriatic Acid, a sump pump, a scrub brush and a towel. You will want to pour a small pool of water into the bottom of your Koi pond, and then mix the muriatic acid in with it. You will then want to place the sump pump in the center of the mixture, and start spraying your pool walls. You will notice a strong acid vapor, which is visible, and also very strong scented. Don’t be alarmed by the loud hissing sound...

Building A Koi Pond

When building your Koi pond, you want to first double check your pre-planning steps. You first want to check with all utility companies to ensure that there are no underground lines that you are going to hit. Each state has at least one Underground Service Alert provider. The Underground Service Alert provider will notify all necessary companies to come out and survey your yard to make sure all lines are sound. If there are no lines running through your yard, or through your plans, the company will mark the road in front of your house “NC” which stands for “No Conflict”. Click Here to find a list of Underground Alert Service providers in all states. You will also want to get a City Permit. Although every City/ State has their own requirements, some general requirements include: A Fixed Enclosure – An approved wall, barrier, or fence that separates the pool from outside objects. Self-Closing, Self-Latching Doors – All...

Water Testing

Water pH It is extremely important to check the pH level in your pond frequently. An acceptable pH ranges between 6 and 8.5. The major concern of pH is the relationship of ammonia and nitrite toxicity. With 7 being neutral, every integer being an exponential increase in toxicities. Any pH level below 7 is considered ‘acidic’, while any pH level above 7 is considered ‘basic’. A pH over 8.5 can lead to fish disease, and eventually death. A higher pH level is generally caused by runoff from mortar, bricks, plant pots, or other runoff. A pH of 9 or more can damage a Koi fish’s kidneys and can lead to death. Adding salt to the water can help by detoxifying nitrites, killing parasites, and controlling algae. Adding too much salt can cause harm though. It is best to keep the salt level at around 0.1%. The mixture should be around 1 tablespoon of salt for every 10 gallons of water. It is very important to know how much...

Sealing

When sealing a pond, you must first make sure of a few things. You want to make sure that the pond is rid of any dirt and debris, as dirt and debris can cause a barrier between your seal and concrete, which can eventually cause cracks, and leaks, and allow bacteria and fungi to grow through your pond. Along with ridding your pond of dirt and debris, you will also want to make sure that it is dry. Once the pond is dry and clean, you want to apply a layer of sealer to a section of your pool. We suggest not applying sealer to the entire pool at once, as you will have to smooth out the layers to avoid clumping and dips where cracks or imperfections may have formed. It is suggested to use a paint roller to apply the sealer. Use extension rods as needed, as you do not want to walk over any fresh sealant. As you apply the first layer of sealant to sections of your pond, you will then want to cover the pond with a tarp, held down by stones or bricks or...

Steel

After the plumbing phase, comes the steel installation. Steel is used to reinforce the concrete in the Koi pond. Although concrete has great compression strength, it has minimal tensile strength. Steel bars, (or rebar), which can withstand high levels of tensile stress are used to create a framework within the concrete to add strength under high levels of pressure from the water within the pond. Using steel in concrete is known as reinforced concrete. The general rule of thumb is to lay the rebar down one way, 12" apart, and then lay it down perpendicular to that, also 12" apart, so you create a 12" x 12" grid. This grid is commonly referred to as either a 12 on 12 grid, or 12 inch on center grid. Places that are more weight-bearing, such as waterfalls or deep areas in a pond, they will use a closer grid, such as 6” x 12”, or 6” x 6” to increase support. Rebar usually runs in 60’ pieces. If the bar is not...

Plumbing

Plumbing is one of the most important processes in building a Koi pond, and also the easiest to run into problems with, as there are so many variables. You want to make sure that you have all proper lengths and widths on pipes, appropriate pumps with the appropriate power, Filter(s), Water leveler, drains, etc. One commonly overlooked specification is finding the correct sized pumps and piping. Originally I used a ___hp pump, and ___ diameter piping. I found that power wasn't distributed evenly throughout the Koi pond, so decided to use ___diameter piping, and 2 ___hp pumps. By doing this I was able to keep even pressure throughout all of the pipes, and in turn keeping happy fish. Also, having several low-pressure pumps keeps electricity costs lower. When determining what size pumps and pipes to use, you want to take into account how long your pipes run, the diameter of your piping, and the height in which water will have to be moved. Using the exact calculation is...

Electrical

When installing electrical, you first want to make sure that you are going to have the supplies that you need. Here is a list of supplies needed for every pond: ½” Conduit, to run from main electrical service panel to equipment ½” Brass, to run from electrical service panel to pool lights Pond Lights GFCI for Pond Lights Light Switch Pump Hookup(s) Bonding equipment for components Before starting your work, you must first remember that all wires and work must be left exposed for inspection. You can have your lines buried, but just not filled in. A good place to start is with the sub-panel. If possible, it is easiest and best to place this as close to your main service panel as possible. Depending on the size of your pool, you will need a specific amperage breaker (generally, a 50A breaker will do, but be sure to calculate your amperage beforehand). You can attach your light fixtures to the steel, as this is a great anchor...

Rock Work

Rock work can be one of the most aesthetically important parts to building a Koi Pond. Having nice rock work can make even the most basic ponds visually appealing. The key to good rock work is planning. Having large, round rocks with flat surfaces helps the building process, as no rocks will need any alterations. Find the rocks that you will want to use, and plan out where you will set them. Once you have done so, you will want to go ahead and lay them into their appropriate places. Note that you will have to dig the ground to form to your rock, like two puzzle pieces. Once you have dug your rock placement, and have the rocks in place, you will want to seal them to the fill. A good product for rock seal is Stonetech rock sealant. This will prevent any water from getting into the cracks, which can cause erosion. If you are stacking rocks on top of each other, for something like a waterfall, you will want to use a standard mortar or grout mix of...

Fixtures

Waterfalls There are several different ways to add a waterfall to your Koi Pond. The first and easiest option is to purchase and install a waterfall kit. This is obviously the easiest, as the kits include all necessary equipment, with instructions on how to install and operate. Several things to look for in a quality waterfall kit include a pump, preferably one that is energy efficient and has a warranty. Depending on the amount of usage, you want to make sure that your pump wont burn out. You can find waterfall kits at most local pool or home garden supply stores. Be sure to research your options beforehand, as there are most likely more options than just what your local supply store carries. The other option is to build a waterfall yourself. In order to do so, you will need the following materials: Rocks Mortar PVC piping A submersible water pump Pond Liner You will first want to play out what you want your waterfall to look like. It is best to...

Fill

Once all electrical work has been completed, you will need to get a Pre-Gunite City Inspection. Once this has been approved, you can start the concrete phase. Shotcrete (concrete applied pneumatically (via air pressure)) is the material that is used to form the ‘shell’ of the Koi pond. On average, Koi ponds are usually 6” thick, and 8” thick in the coves (the bent area between the wall and floor of the Koi pond). The top 6” of the Koi pond is called the bond beam. The bond beam is usually 12” thick to increase the structural integrity of the Koi pond. Shotcrete is applied at 100 – 150 psi pressure. This works to compress the concrete, causing a stronger bond that can withstand more pressure, and has less of a chance of cracking. Shotcrete is the common method to pouring a Koi pond because no forms are needed. The concrete used is generally low-slump, meaning low in moisture. The low-slump...

Asagi

(Ah-Sog-Ee) Asagi are fully scaled, nonmetallic fish with a long history, but because they closely resemble Magoi (the wild black carp). Some hobbyists see them as unrefined, dull, and not proper koi at all. Certainly they are an acquired taste, far removed from the brilliantly tri colored modern Showa or the flashy koi grouped in Hikariutsuri. But their quiet elegance serves as a counterpart to their more exotic pond mates and they also have the potential to grow very large. Asagi have a long, yet simple history. The Asagi Magoi, one of the three recognized types of Magoi, is said to be the forerunner of all modern koi breeds. About 160 years ago, two mutants koi types arose from this proto-koi, namely the Konjo and the Narumi Asagi. Although instrumental in the development of Matsuba koi, the dark Konjo Asagi were not seen as having any value, and were kept mostly for food stock. However, Narumi Asagi have gone on to become one half of a recognized judging variety - the other...

Koi Fish

Bekko

The Bekko Koi Fish is usually a white fish with black markings. The Bekko has also been known to be red, or yellow with black markings. The white Bekko is known as the Shiro Bekko Koi, the yellow is known as the Aka Bekko, and the red is known as the Ki Bekko. The Japanese translation means “tortoise shell.” The Bekko is commonly mistaken for the Utsuri Koi Fish.

Goromo

The Goromo Koi Fish is very similar to the standard Kohaku Koi, except instead of having the standard red patches, the edges of the scales normally have a black or blue hue to them. The breed of fish is a hybrid of the Kohaku and the Asagi Koi Fish. The breed came about in the 1950s.

Koi Fish

Kikokuryu

Kikokuryu are the metallic version of Kumonryu. Where the Kumonryu has muted, matte white and soft, deep black, the Kikokuryu has a metallic platinum-white and a glossy, lacquer-black. Kikokuryu originated from a crossing of Kumonryu and Platinum Ogon brood stock. What To Look For: Similar to Kumonryu, the pattern of any single Kikokuryu will change completely many times throughout it\'s lifespan. For this reason, body conformation and the quality of the colors themselves (but not the pattern) should be the first things considered when choosing a Kikokuryu. Be aware that if you buy a Kikokuryu solely for the pattern that it displays at the time of purchase, it is likely to change to a completely different pattern within a few months, if not sooner.
