Contrary to common belief, biological filters do not process or filter the solid waste of fish in your koi pond. They continue to build up and putrefy, creating a breeding ground for harmful species of heterotrophic bacteria which are pathogenic to koi fish. As stated, the biological filtration process utilizes Nitrosomonas bacteria to break down ammonia into nitrite and nitrobacter, further converting nitrites into nitrates, which is less harmful to koi fish.
Plants now utilize the nitrate and phosphate for fertilizer; if you have not provided an adequate ratio of water plants to koi fish, "hard" algae (growing on rocks and koi pond walls) and "free- floating" algae use nitrate and phosphate to reproduce.
The key to preventing this condition, called "algae bloom," is to provide enough non-soil bearing plants such as water lettuce and hyacinths to compete for the nitrate and phosphate. Since these two plants are tropical and can only survive in warm climates, hardier varieties such as Elodea and Anacharis will perform well in cold climates. These plants are commonly used in bio-filter ponds.
A bio-filter pond is used in conjunction with shallow koi ponds with small populations of koi fish. It will also eliminate the need for a mechanical bio-filter and a second pump to operate it.
The bio-filter pond is located higher than the main pond for two reasons. It prevents the koi fish from eating the plants and it allows the water from the waterfall to be filtered as it passes through the plants prior to spilling into the lower koi pond.
An adequate ratio of plant cover for the koi pond's surface is approximately 20 to 30 percent. This is a basic rule of thumb and many factors can change this equation.
For example: koi fish population, water temperature, and debris accumulating from leaves or over-feeding the koi fish. I have said many times that the Koi Pond is the koi's living room, dining room and toilet.
If you do not have a bio-filter, that could explain why your koi pond is a tad green, stinky, or cloudy, and why your finned family is gulping air on the surface. Trust me. That will not be for long. Fish gulping air to survive would be like you -- in an attempt to avoid breathing poisoned air -- gulping water to survive.
If you do not already have a biological filter, I can not encougage you enough to abtain one. If your pond is over eight hundred gallons, and you are using an above ground pump that produces over 3500 gallons per hour, I suggest a pressurized bead filter. I cover the topic of biofilters in greater detail in another article. Happy koi, peace and joy.
Koi Pond Filter System
A biological Koi pond filter saves precious Koi from themselves. Let's face it, Koi eat like there's no tomorrow. All that eating, in a garden pond environment, makes for a dynamic living, swimming, eating biological hazard machine. The mounting waste Koi produce amounts to rising levels of toxic compounds in the water, the most common being ammonia and nitrate. It's not such a big deal when the levels of these toxins are kept under control. However, a spike in ammonia or nitrate levels in the pond water could kill your Koi. In the wild, this process is taken care of by either the sheer volume of water, and/or the current of moving water taking waste particles along with it. In a garden pond setting, we need to supply this process mechanically.
When entering the market for a Koi pond filter be sure to consider the fish first, not the price. If your Koi's health is of importance to you, then you will want to take every measure to ensure their quality and longevity of life. Clean water is not only a key to their survival, but also a key to your peace of mind. Let's face it; the cute little fishes need you. They are living beings that will depend on you to look after them for the life they spend in the pond environment you establish for them. Wow? how's that for a reality check?
The Koi pond filter has much to do in continuously maintaining the cleanliness of the pond water. Consider the number of fish you are intending to keep in your pond, along with how large or small the pond is itself. Koi are voracious eaters, and in turn they produce a substantial amount of waste. Because of their avid appetites, Koi also have a tendency to grow very large and very fast depending on the circumstances. Facts such as these need to be understood when keeping Koi, especially if you plan on adding more fish to the pond at a later date. A solid, reliable biological Koi pond filter is a necessity, and should be looked upon as a predominant link in the lifeline you supply them.
It is a good idea to take your time in understanding pond filtration, as this will give you some insight into what your role will be in terms of pond filter maintenance and up keep. Explore your options with a specialist at your local pet store, or with a reputable Kio pond expert who will assist you in configuring the right pond filtration system for your specific requirements. As with many things, there are countless brands, makes and models of Koi pond filter to choose from. Getting your head around it all can seem quite daunting on the outset, especially when you will be factoring in what pond pump and other equipment to use along with the filter. However, getting your figures and information together before hand can help alleviate much of the uncertainty when deciding on which pond filter to go with. It can not be stated enough that cutting corners on filtering equipment up front could cost you dearly further down the road if you loose some or even all of your beautiful Koi fish. It is wise to agree that money and frustration are saved when you take pride in making the right decision on installing a Koi pond filter system right the first time. Yes, it costs a little more to buy the best? but aren't they worth it?
