Koi Pond In The Spring

Making sure your pond is ready for the coming seasons should not take you more then a weekend to complete, and will ensure that you have a successful water garden for the remainder of the year.             

KOI POND IN THE SPRING

Your Koi pond will literally come to life at the first of springtime. The Living organisms in your pond have spent the previous winter in a proverbial hibernation, and are ready to come to life at the first signs of warm weather. 

Spring is the perfect time to begin maintenance on your pond before the fish, plants, and other pond life come back to live from their winter slumber. As the days begin to get warmer, your pond will start drastically changing. 

If you are not careful, you may miss this much needed opportunity to perform maintenance. Generally, watch for temperatures around 50 degrees, as this is the perfect time.

The maintenance needed on your pond will largely depend on what happened during the previous winter. If the previous winter was hard, chances are you will need to perform more changes, so it may be a good idea to start as soon as you start noticing the weather changes. 

However, some spring maintenance will have to be completed every year, no matter how harsh or how mild the previous winter was.

Water Quality

You may notice that the water in your pond is extremely clear when the seasons are changing from Winter to Spring. Do not let this fool you, as there are several factors that will actually cause problems once Summer comes if you do not remedy these issues ahead of time.

Water Remedy

 During the Fall and Winter months, organic material such as leafs and plant material may have found it’s way into your pond. While the water seems clear at the time, the organic material placed a large amount of nutrients into your pond, which will cause a surge of algae growth once spring arrives. 

If algae was not enough, the large amount of organic material in your pond will start to decompose, and will reduce the oxygen content in your water.

Since your water is perfectly clear, it is the perfect time to clear all of this unwanted debris and slit from your pond. This can be completed a number of ways.

1) Hire a pond professional from your local dealer or pet store. They will have the equipment needed to vacuum the majority of the debris and slit out of your pond. While this is a more costly option, you will have the assurance that the majority of the problem causing material will be removed from your pond. 

2) If hiring a professional is not an option, you may want to consider using a fine mesh net to scoop up as much debris as possible. The only issue is most nets will only stir up the slit in your pond, rather then remove it.

Once you have removed unwanted debris, you must then test your water. Winter seems to cause the pH levels to change. At the start of Spring, your pH level should be an 8. 


This can be achieved by topping your pond off with treated tap water which is buffered to be slightly alkaline by your local water company.

Maintaining your Koi Fish

Spring time is a very weak time for your fish, because they have not eaten for months, and have may be living on a low level of energy. This cause your Koi to be more susceptible to attacks from organisms such as bacteria, parasites, viruses, and fungi. 

This makes Spring the opportune time to take all preventative measures possible. Adding a large spectrum of treatment solutions will greatly reduce the amount of disease causing pests and material. 

Once the temperature warms up, another dose of this treatment will ensure that your Koi will be well protected while they redevelop their immune systems. Once temperatures warm up, your Koi immune systems will be effective enough to protect themselves from disease.

Strangling Koi-Could The Cause Be Lurking In The Filters?

Remember even a crystal clear pond might contain toxic levels of chemicals potentially lethal to your Koi, while an algae bloom might look repulsive; (makes it challenging or impossible to see your Koi) but actually could be beneficial to your Koi.

Butterfly Koi

Koi ponds are artificial self-contained ecosystems. Koi are ammonotelic, that is, the majority of their nitrogenous waste is excreted by diffusion (the movement of a substance from an area of higher concentration to one of lower concentration attempting to achieve equilibrium) via the gills, into the water, as ammonia. Ammonia is excreted in two forms: NH3 the toxic form, and NH4+ the ionized and nontoxic form.

The relationship between these two forms is greatly pH and temperature

dependent;-The higher (more alkaline) the pH, the greater the amount of (toxic) NH3, while the lower (more acidic) the pH, the greater the amount of (nontoxic) NH4+- The warmer the water, the more NH3, the colder, the more NH4+.

Because the unionized form of ammonia (NH3) is the toxic form, and because this form is more prevalent at higher pH and temperatures, ammonia-Becomes dramatically more toxic with increasing pH & temperature.

From Roark’s web site: www.click2roark.com biofilters  become populated with families of bacteria that convert ammonia to nitrite. Nitrite is also a very toxic substance.

Unlike ammonia, it does not come directly from Koi, but is formed almost solely in the filter or source of that family of bacteria. Because nitrite does not come from the Koi, when it contacts the Koi’s gills it enters the fish by diffusion (again from the area of higher concentration, the pond, into the lower concentration of the Koi blood) binding hemoglobin in blood rendering it unable to carry oxygen.

A second population of bacteria grow in our biofilters to convert nitrite to nitrate, fairly harmless to Koi but usable by algae and plants. As the Koi eat the algae and plants, this cycle begins all over again. The bacteria that convert nitrite to nitrate are the most susceptible to aberrations in water quality and are therefore the first to decrease in number ammonia is harmful to Koi, and even extremely small amounts in the water over an extended time may cause permanent gill damage.

Treatment for high nitrite includes water changes, suspended feeding, salting to 0.1% and increased oxygenation. Again, these are meant to temporarily improve the situation until the filter is working.

In all cases address the underlying causes- start with checking your filter. In the spring, check ammonia, nitrite, pH and KH (total alkalinity or Carbonates) with your test kits daily until your bacterial colonies are populated each spring, then weekly during the summer. An ounce of prevention is worth pound of cure. These forthright simple precautions can prevent a small problem evolving into a catastrophe failure and your investment is shattered.

Good Or Bad Bacteria-What Is It

All Koi Ponds Have Good and Bad Bacteria

Pond bacteria are present in nearly all ponds, except those ponds built to contain only pure, clean and sterile water. Artificial ponds need chemical agents such as bleach to eliminate any pond bacteria that may possibly come out. Otherwise, most ponds found in gardens or landscaped areas also known as "living ponds" are inhibited by good and bad bacteria.

Bad Bacteria

Just like the bacteria we have in our bodies, there are generally both good and bad bacteria present in pond water. Whereas, the good bacteria help people break down the food, while the bad ones trigger disease, inflammation, or even infection.


Pond bacteria are no different: there are good bacteria and bad bacteria. Good bacteria fight off bad bacteria to keep them from coming back, while bad bacteria infest water and its organisms.


Bad Pond Bacteria - http://Nishiki-colorfulkoi.blogspot.com Bacteria for ponds are generally small to be individually seen by naked eye, but they are recognizable by way of alterations in water colors, the existence of pond scum and algae, as well as foul odors such as methane. The most troublesome is the algae build-up. Algae have many various types, several thousand in fact.


Algae are commonly categorized as fungi instead of bacteria, but they are dealt exactly like bacteria. Several kinds of algae create an unwanted appearance to ponds and can be very harmful.


Wildlife as well as domesticated creatures can get water-borne diseases and even die once it consumed water infested by harmful algae. Humans directly into contact with algae infested pond water can experience skin rashes or irritation, eye, nose and throat irritation, and other illnesses.


Good Pond Bacteria - Whereas bad algae often thrive on decaying plant material and animal waste, the good pond bacteria normally thrive on the bad bacteria and consume the latter's food sources.

Good Bacteria

Good pond bacteria are usually weak and thrive only under limited conditions. One kind of good bacterium is sludge remover. The sludge removers feast on dead substances from ponds, removing a food source essential to various kinds of bad bacteria.


Another kind of good bacteria are nitrifies. These kinds multiply slowly. Nitrifies role is converting ammonia into nitrites and then into harmless nitrates.


Periodic Waste Removal -The ideal approach to maintain good bacteria is by removing dead materials periodically. A natural pond cannot be "cleaned' just like a pool, primarily because it is hosting plant and marine life.

However, you have to be careful in the particles or substances that fall off the pond and avoid overfeeding fish that greatly contribute to bacterial growth. One good promoter of algae development is direct sunlight.


Eliminating undesirable pond bacteria is definitely an extensive process, particularly if the pond water is stagnant. Installing a water fountain, an aerator, or anything that promotes movement of water can be a significant help in cleaning a pond.


As what has been noted previously, pond bacteria are too small to be seen; however, once you succeed in removing algae, pond scum, sludge, and clarify the water, you've probably won the battle-- although the war may continue over time.
