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.

With Koi pond equipment, as with everything there are both wants and needs. You must be able to determine which are which.

There are also some types of equipment that, while not necessities, make caring for your pond so much easier that you should acquire them if you are able to.

Remember also that you will need to make decisions on some of these things during the initial stages of your Koi pond design and construction. If you leave out the necessities at the beginning it will cost you many times over to add them later.

NEEDS:

Pond Filter:   This piece of equipment is the “heart” of your Koi pond.  It keeps the water clean and healthy for your fish. The filter plays two very important roles. First, it mechanically removes fish waste and anything else that causes cloudiness in your pond.  Second, biological filtering changes the ammonia in your pond into nitrites and then to nitrates which renders them less toxic to your fish.

Bottom Drain:   Bottom drains are of the utmost importance in order to have a successful Koi pond.  Some ponds even need several bottom drains. Without a bottom drain your filter can’t do it’s job correctly.

Pump:   The last piece of necessary Koi pond equipment is your pump. You will want a large enough pump to send all your pond water through your filter every two to three hours. There are several factors to consider when choosing a pump. Make sure you choose an efficient pump designed specifically for Koi ponds.

These are the things you cannot do without to maintain a happy and healthy environment for your Koi. Make sure to invest in quality models of these pieces of Koi pond equipment!

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!
