Koi filtration is probably the most important mechanical function in your pond! Without a filter you won’t be able to keep your water clean and we all should know by now that the most critical factor in koi health is water quality!

I just put up a new Squidoo lens about the koi pond filter. It provides information on the basics of koi filters, how they work and what they do.

Different aspects of filtering are reviewed and you will find out where you can go to save money on all your koi pond filtration needs!

Don’t neglect to learn all you can about the koi filter that you may already have, or that you will purchase in the future. Your filter determines, to a degree (along with the size of your pond), how many koi your koi fish pond will be able to sustain, how quickly and large your koi will grow and how healthy they will be.

For any pond over 1000 gallons it is wise to use a pressurized biological sand or bead filter that can be back washed. There are pros and cons with either sand or beads.

During the backwash portion of the operation, sand, since it is heavier than water, falls to the bottom of the tank instead of flowing out through the valve with the waste. Plastic beads, since they are lighter than water, float to the top. As they are smaller than the valve-strainer’s holes, they get washed out through the valve into the waste stream. More and more beads are lost during each backwash operation.

Bead filters also have limited efficiency. Smaller beads have more surface area for good bacteria colonization, but tend to get flushed out during the backwash procedure. This doesn’t happen to the larger sized beads, but they have less surface area and thus are unable to filter as efficiently.

By under-loading the sand filters, and backwashing them more frequently with higher pressures and flow rates, you can take advantage of the greater food processing surface areas, while eliminating the chance of plugging, which can be their main fault. Many manufacturers recommendations for loading sand tend to be too high.

This causes the sand to plug the filter which is the main drawback of sand as a filtration medium.

Up-flow and gravity flow filters need to be cleaned regularly and it is a filthy job. The filter media is packed with rotting organic matter and foul odored fish waste .

As you clean and handle all the various parts of these filters you will find small, white feces-eating worms crawling on your hands and arms. Add to this the ambiance of the offensive odor described above and you don’t exactly have nirvana!

The up-flow and gravity flow filters, though inexpensive to make, cost a fortune to purchase. So, in addition to paying a premium price to buy one, you are also spending so much time and labor that you might as well have paid at least twice the price!

If you use a pressurized filter, all it takes is the turn of a handle for 2 to 3 minutes and the filter is clean. Almost like magic! This saves lots of time, inconvenience, labor, mess, and wear and tear on your Koi. It uses slightly more electricity to operate a pressurized pump, but the savings in labor more than make up for it in most pond owner’s eyes!

You can also use the waste water for your plants. It is packed with nitrogen and works even better than many of the fertilizers created especially for this purpose!

As you can see, to find the type that is right for you, you have several decisions to make about Koi pond filtration.

These pieces of Koi pond equipment, while not exactly necessities, are well worth the cost and you should acquire them if you can!

ALMOST NEEDS:

Skimmer: Your skimmer draws in surface debris. It is possible to do this manually with a net and by using a pond vacuum to get any debris that makes it’s way to the bottom of your pond. If you can afford to get one it greatly cuts down on your labor!

UV Light: A UV light is especially helpful in newer ponds until beneficial bacteria is established as your pond matures. This piece of Koi pond equipment kills algal blooms that float about suspended in your pond water. Two things to note; you need the proper size for your pond or it won’t be effective and UV lights don’t kill string algae as it’s attached and doesn’t float about in your pond.

Jets: People that have jets in their ponds say that they would never want to do without them. While not a necessity they do provide exercises for your Koi who are river fish and enjoy swimming in a current. If you install them in the right places you can move water out of “dead” areas of your pond and direct it towards the skimmer where debris can be collected. Also if they are installed so the water breaks the surface they can help to oxygenate your pond! As you can see they provide many benefits.

Auto-fills: While far from being a necessity an auto-fill makes maintaining your pond easier. As it’s name implies it always keeps your water at a pre-determined level. As water evaporates it is automatically replaced. This reduces the risk of forgetting to turn off the hose and inadvertently killing your fish by chlorination.

WANTS:

I consider pre-filters, underwater lights and automatic feeders to be in the “wants” category. They may be nice to have but definitely not necessities.

These are the basics, although there are definitely more details to consider when you choose specific pieces of Koi pond equipment.

In my opinion all Koi ponds should be at least three feet deep and not have any areas of the pond that are less than two feet deep!

All of the sides of the pond should go almost straight down rather than tapering. The pond just won’t be safe for your Koi otherwise. If you have any spots, particularly near the edge of the pond, that are less than two feet deep it is like sending out an open invitation to dinner to all the raccoons and blue heron in the area.

Even if you think you live in a relatively predator-free area you will find out differently if you don’t construct your pond defensively when it comes to depth. You might think your fish are safe if you have built a deep area with a cave for your Koi to hide in, but it will still be no match for the blue heron.

This Koi predator will simply wade out into your pond and wait patiently for the fish to come out of hiding.

It is much more aesthetically pleasing to build your pond properly than to find out later that it’s necessary to cover it with a net. A deep pond with steep sides is the best defense against Koi predators.

Another thing to know about depth is that Koi get the most exercise by swimming up and down in the pond as opposed to back and forth, thus to raise healthy, large Koi three feet deep is just the bare minimum. You might want to include an area up to six feet in depth to provide for plenty of exercise as well as safety.

There is a little room to play with when figuring depths for your Koi pond but make sure you take the forgoing tips seriously when planing your Koi pond design!

When you are deciding about the placement of your Koi pond there are several things to consider.

First, koi ponds do better in a shaded or partially shaded spot than in full sun.

You can place a Koi pond in full sun, but a shadier area will  slow algae growth considerably and helps prevent the water from becoming too hot during the warm summer months.

If you build your pond in a sunny location you might want to consider putting up an arbor or awning to provide your pond with some shade.

Shade also helps with protecting your Koi from predators…it gives them a place to hide. And, believe it or not, Koi can get sunburned so having some shade gives them a place to go to keep out of the direct sunlight!

Leaves from trees near the pond, with the exception of pines, shouldn’t cause problems  if your pond is well designed.  Pine needles can create quite a mess as they can make their way through skimmers and leaf baskets and clog up your pump.

Once you have picked a spot and decided on a shape for your pond you can use a garden hose or rope to outline it’s size and shape.  This will give you some idea of  how the pond will look.

Keep in mind that your new Koi pond will probably be the central feature of your landscaping. Once you have the general outline shape of the pond established you can get a approximate idea of how many gallons it would be by multiplying the average length by the average width by the average depth by 7.5 gallons per cubic foot.

You’ll still have quite a few decisions to make but you’ll have a good starting point!

Happy pond designing!

One of the most common mistakes people make when designing their first Koi pond is that they plan to build it too small.

The smallest pond I would recommend building is 1500 gallons, which would be approximately 7 feet wide by 8 feet long and 4 feet deep.

This may sound very large to some people, but if you build a pond much smaller than that, you will probably not end up being happy with it.

One of the problems is that Koi fish are extremely addictive and just like with Lay’s potato chips, it is hard to be happy with just a few!

You also need to keep in mind that you may start out with several 6 inch long Koi, but within 3 to 4 years they could grow to be 2 feet long or more.

With very few exceptions, most people end up wishing they had made their first pond bigger.

Bigger isn’t always better though. The largest pond I would recommend building is 15,000 gallons. The dimensions would be approximately 17 feet wide by 21 feet long and 6 feet deep.

A Koi pond design much larger than that can cause you several problems. For example it can become almost impossible to catch one of the fish if you need to.

If it becomes necessary to medicate the pond it will become more expensive the larger your pond gets. In addition, all the water in the pond will need to be filtered at least once every three hours. Operating pumps large enough to get the job done can cost hundreds of dollars per month.

Last, but not least, if you design a pond that is too large you won’t be able to enjoy your Koi as much because the larger the pond the less your fish will be visible.

Make sure to plan your Koi pond design carefully to comfortably accomodate your Koi and please your sense of aesthetics!

To create a lush water garden design that enhances your beautiful fish you will want to choose a variety of Koi pond plants so that you have a balanced look and ecosystem. There are several types of plants you can include.

Water Hyacinth is a beautiful and functional Koi pond plant

The first type are SUBMERGED PLANTS like Anacharis and Cabomba. These are planted underwater in the gravel or soil and they will help to oxygenate your pond. They do this by pulling carbon dioxide from the water and releasing oxygen as part of the photosynthesis process.

Another type are the FLOATING PLANTS. Many of these plants provide your garden with lovely flowers. The root systems that drift below the surface actually act like a filtration device, which is why some sanitation plants use Water Hyacinth as part of their purification process. Plants such as the Water Hyacinth and Water Lettuce also may serve as camouflage for your pond filter or other pond equipment.

MARGINAL PLANTS like Cattails and Irises do best in the shallow water or wet soil around the edge of your Koi pond. They grow up above the water. Marginal Koi pond plants make an ideal way to transition from pond to the surrounding area in a gradual way.

The final type of pond plants are FLOWERING WATER LILIES. They are the essence of any

Water Lilys provide shade and are a nice addition to any Koi pond.

water garden or Koi pond. They are similar to marginal plants in that their roots grow underwater, while the leaves and flowers emerge above the surface. Lilies will spread across your pond surface. They aid in providing shade and shelter as well as aesthetic appeal.

The following are some of the items that are necessary for planting and tending to your Koi pond plants:

~Planting Baskets These baskets will contain and anchor your plants on submerged shelves. You can also use floating island planters to create one-of-a-kind floating arrangements.

~Aquatic Planting Media boosts the ability of root systems to gain a firm foothold and get well established for the growing season.

~Aquatic Fertilizers are used to promote blooms, lush foliage, and strong roots in aquatic plants.

~Pruning Tools give you the extra reach to trim and sculpt plants for a well-manicured Koi water garden.

The above suggestions include the basics that will give you a good start on planting and maintaining beautiful and healthy Koi pond plants.

Today I’m posting a letter that I just sent out to my email
list. The content is important so I wanted to make sure that my blog
readers get it too!

“I thought I’d send along an article I came across the other day.

Hopefully you know that you don’t want to place your Koi pond at the
bottom of a slope. That way if there is any pesticide runoff from a
garden or from your lawn it won’t be directed towards your pond.

Koi are fairly hardy but contaminating their water with pesticides
can kill even the hardiest of Koi.

In fact the three most important components of Koi care are:
1. Water Quality
2. Water Quality and
3. Water Quality

It’s that important.

I hope you find the article interesting and that it drives home the
point. You probably won’t ever run into this extreme (hopefully) but
it won’t hurt to keep this in mind.

There is no reason that Koi and Koi pond plants can’t co-exist, however many Koi owners are very reluctant to mix the two. The main reason for this is that these fish are voracious eaters and will consume almost anything they can fit into their mouths!

Koi are by nature very curious and each has a unique personality. Koi pond plants might become food, provide entertainment or even be ignored. Unfortunately there is no way to predict how your particular fish will react.

Koi & Pond Plants

In general it works out better to introduce your Koi into a planted pond than to introduce a Koi pond plant into an established Koi pond. Koi are curious fish and will go over to investigate the new addition. Then, if one begins to nibble on the plant they will all nibble on the plant as they learn from each other.

However, if you put a few new Koi into an already planted pond chances are that they’ll probably leave the plants alone. Exploring a new environment and finding new things to do can occupy them, thus providing a bit of protection for the plants.

Koi pond plants that have recently been potted do not have well developed root systems to help hold the soil in the pot and the plant in the soil. If your Koi can find any way to get to the soil they will uproot your plant. Rooting is an instinctive behavior for members of the carp family.

One way to keep them out of the soil is to place rocks on top of the dirt. Of course this only works when the rocks are larger than the Koi’s mouth and it won’t prevent them from pushing the rocks out of the pot.

To prevent that from happening you can plant in a pot that is two or more times deeper than the dirt. If the Koi want to get at the dirt they’ll have to stand on their head which is quite uncomfortable for them. Even so, you still need to place the rocks over the soil.

Another option for protecting roots is to grow your Koi pond plants without soil. You can plant them in plastic net baskets with golf-ball size lava rocks. The fish aren’t interested in the rough textured rock, your plants will get their nutrients from the water and the spaces in the rocks allow bacteria to grow. This method will both help keep the Koi away from the roots and help keep your pond water clear.

Leaves are considered a delicacy by bored or hungry Koi fish. There are a couple of ways to handle this problem. You can make sure your Koi are well fed and offered a variety of foods, including fresh and / or rotate pots in and out of the pond. Pots sitting out of the pond give plants a chance to recover while the pots in the pond are available as a tasty snack! Watercress and water celery are particularly good for this.

Keep the plants that you most want to protect in shallower water and at the edges of your pond to make them harder for your Koi to reach. They aren’t averse to coming up out of the water a little ways to get to a delicious meal!

The addition of fast multiplying duckweed or mosquito fern to the pond offer a nice alternative to your more prized Koi pond plants.

As your Koi get larger you might need to separate your plants from your fish. Often barriers can work well. Most of these include netting with holes just large enough for Koi fry and water currents to pass through. Your success rate with netting can vary as the fish can learn to wiggle over the floating nets. If one does it the others
wil surely follow since Koi are quick learners. However you could get lucky and they may not figure it out.

Koi pond plants

Some Koi enthusiasts build cages from wire around their plants and this can work well as long as you are certain that there are no sharp edges for your fish to get scratched on. Opportunistic diseases can take over if an open sore or scratch is available to fester in.

A last thing to keep in mind is that many Koi ailments are treated with salt and some Koi keepers keep a minimum salt level in their ponds. This is probably okay as long as it is a very low level. A pound of salt per 100 gallons of water will kill all of the submerged plants.

If you have a sick fish and want to medically treat i with salt you will need a higher concentration and should remove it to a seperate tank for treatment purposes.

If you are careful and do some planning you should have very little trouble with Koi pond plants.

There are many excellent reasons that you should invest some time and money in Koi pond plants. They do involve a little bit of work but they provide many important benefits.

The first thing you need to know about Koi pond plants is whether or not you really need them. They do involve a bit of work but they provide many benefits.

First of all they help keep your pond clean, balanced and algae free. Pond plants feed on unwanted nutrients like fish waste and nitrogen. These are the same materials that feed algae and allow them to flourish. Since algae and Koi pond plants compete for the same food and pond plants are higher on the food chain, they starve off new algae growth.

Plants can beautify your pond.

The best combination for your Koi pond is: lots of live plants & good filtration & a minimal amount of fish = a healthy ecosystem…AKA a clean pond!

Some other reasons that you need Koi pond plants include:

1. They provide cover for your Koi, thus preventing things like sunburn (yes, Koi can sunburn!) and predation from birds. Birds, with their keen eyesight have no problem locating your colorful Koi and swooping in to scoop them out of your pond.
2. As already stated they help reduce algae problems.
3. Pond plants help lower the water temperature of the pond thereby also lowering the day-night temperature differential of your pond. This helps reduce environmental stress on your Koi.
4. Another benefit of Koi pond plants is that they help lower evaporation rates…
5. And they provide nice, shady areas for your fish to relax in.

Pond plants provide cover for your Koi.

6. The plants in your pond help also help keep your fish well fed. They do this in two ways. First, they trap some of the floating fish food, giving your Koi another chance at it before the pond skimmer gets it. Secondly, as Koi are voracious eaters, the plants themselves provide a “fresh food” source for them. No matter what you do you are going to have to plan on periodically replacing some of your plants. Your Koi won’t be able to resist them!
7. Pond plants also provide excellent cover for Koi fry (Koi babies). While you may not plan on raising any babies they will still be born and having pond plants ensures that at least a few will survive.
8. Some of the plants in your pond will (and should be) oxygenator plants. The best plant for fast growth and best water filtration is the water hyacinth. The oxygenator plants are the backbone of what aquaculture is intended for. They filter contaminants out of the water and produce new oxygen.
9. Last but not least, the plant life in your pond creates a beautiful backdrop for your colorful and elegant fish! Don’t underestimate the aesthetic beauty they will add to your Koi experience.

As you can see, there are many excellent reasons that you should invest your time and money in Koi pond plants!
