Perfecting Pairings: OASE FiltoClear & Atlantic FilterFalls

Atlantic and OASE are great partners with complementary product lines that dovetail perfectly to enhance water quality and reduce maintenance. We complement each other on a number of levels, including filtration philosophies. Here in the States, where leaves and clippings are typically the major maintenance concern, we clean from the top, skimming the surface of the pond to capture floating leaves and debris before they can sink. The pump lives in the skimmer, sending the prefiltered water up to an upflow biofilter, where pads clean and clear water mechanically and biologically.

In Europe, fishponds are typically cleaned from the bottom. There, a solids-handling pump on the bottom sends fish wastes and small particulates to extremely efficient pressure filters that remove much finer suspended solids than upflow biofilters can.

The two philosophies are yin and yang; one continually removes leaves and floating debris but requires periodic cleaning of settled solids; the other captures the settling solids but requires vacuuming to remove leaves and larger debris. Put the two together and you get top down, bottom up cleaning that dramatically improves water quality and drastically reduces maintenance.

Let’s take for example any existing fish pond here in the States with a Skimmer and FilterFalls. Let’s say this pond is a few years old and the fish in it are happy and healthy. That means they’ll be big and fat from constant overfeeding and there will be way too many of them, both because they’ve reproduced and because their owners will have added fish – “only a few, here and there, really!” Yeah, right.

Now there are more wastes than the original equipment was designed to handle. Even with additional mats in the FilterFalls, the excess nutrients have started to impact water quality and clarity, as algae take advantage of the constant nitrates in the water column. The homeowners have an aeration system, and are adding bacteria, but the pond just isn’t as clear and clean as it was with one fifth the fish load. Nor are the doting ‘parents’ willing to part with a single one of their cherished ‘children’, all of whom have cute names and endearing habits. So, there are more fish and fish wastes than the pond can metabolize naturally and even an aggressive cleanout will only delay the return of the same conditions.

The contractor now can offer a return to gin-clear water, guaranteed, without rebuilding the pond. A properly sized OASE FiltoClear Pressure Filter paired with an AquaMax Eco pump is the perfect drop-in solution and comes with the OASE Clear Water Guarantee. The system works in three ways to clean and clear the water. The pump, placed centrally at the bottom of the pond, begins pulling in wastes and passing them to the FiltoClear as soon as it is plugged in. The UVC Clarifier inside the filter renders any algae in the water sterile, unable to reproduce, eliminating green water. The ‘foams’ or sponges in the filter trap suspended wastes, returning clean, clear water to the pond. Maintenance is easy; the filter backwashes clean in seconds. The pump is designed to pass wastes without clogging and can go entire seasons without needing to be cleaned. 

Installation requires hiding the pump, its cord and the return hose, a matter of moving and maybe adding a few stones. The filter can be hidden from view either by placement far from the pond’s edge or behind a raised waterfall. The filtered water can be returned anywhere into the stream or along the pond perimeter. Two additional plugs will have to be accommodated, one for the pump and one for the integrated UVC, with a combined draw of only about 2 amps, the circuit powering the original pump may be able to handle it. Even if a second circuit needs to be added, this solution requires much less time and labor than a pond rebuild or even a full pond cleanout.

Finally, a drop-in solution for ponds with water quality concerns that guarantees clear water in ponds up to 2000 gallons. For larger ponds, use OASE BioTec Screenmatic² and ProfiClear Filters with the appropriate UVC Clarifier and pump to achieve the same results, with clear water guaranteed.

The Most Valuable Koi

So we all know what ‘koi’ are, and we have an inkling that there are serious collectors – koi kichi – out there. That makes them valuable, at least to some people. But how much could a fish, even a big fish, even a very pretty fish, actually be worth, and why? 

Well, there was once a very beautiful nishikigoi in Japan, of the type first developed over two hundred years ago. This stunning fish was a Kohaku, white with red patches pleasingly distributed over her body. What made her exceptionally lovely was the intensity of her colors, and the absolute crisp delineation between the white and red. All the borders were sharp and crisp. The red patches were perfect, all the same unvaried shade without blotching or faded areas. The white field they overlaid was equally without stain, a perfect white. She had no other markings, and no imperfections. At nine years old, the three-foot-three-inch fish had perfect fins and her body the ideal shape, swelling to its largest girth midway between her head and tail, perfectly symmetrical. Her breeders, Saki Fish Farm in Hiroshima Japan, auctioned in October of 2018. At the gavel’s drop, a young lady from Taiwan with a family background in koi, Miss Yingying, paid 203 million yen for S Legend, as the carp is called. 

That’s $1.8 MILLION BUCKS for a fish! What’s even more amazing is Miss Yingying Chung’s story, but that’s for you to look up.… 

And remember, when you’re ready for your million dollar koi, Atlantic-OASE has the pond equipment for you!

So You Want to Put in a Koi Pond!

There are many good reasons to want to keep ornamental carp, known as koi fish. First and most of all, they are friendly, engaging creatures that will recognize and respond to you. It’s a great feeling to see a whole shoal of happy, HUNGRY jewel-colored fish churning the water to reach you. Yes they learn, quickly and well, to expect food, but they respond to you whether you have food for them or not, every time. It’s delightful. 

They are very beautiful animals by any measure. Their colors are marvelous, with hues from the deepest reds through orange, true gold, silver, pearly white, black, greys of every shade, even blues. Many varieties sport glittering reflective and metallic scales, in different patterns on their bodies, that literally sparkle in sunlight. Their fins can be equally enchanting, especially those of the type commonly known as butterfly koi. When they aren’t racing to you for food, their long flowing fins swirl around them as they dance gracefully in a synchronized ballet, the rhythmic, circular patterns they describe soothing, relaxing, almost hypnotic. One can get lost for hours just staring at their languid movements in a deep, clear pool, I can personally assure you. 

But to enjoy them at their best you must provide a healthy environment for them. The best koi ponds will ideally be large and deep enough for the fish to exercise in both horizontal and vertical directions; three feet is usually cited as the minimum depth for happy koi. The optimal volume per fish is harder to pin down, but experts and aficionados (koi kichi) like 100 gallons per inch of fish; bigger is always better as far as volume goes. That said, koi will adapt to smaller bodies of water, but they will not attain the same size and run the risk of greater mortality in smaller, shallow ponds for a number of reasons, including more exposure to predators and greater temperature and pH swings.  

Water quality is critical, especially with animals that feed (and defecate) with such gusto. In Japan many ponds have a constant source of fresh spring water to flush out wastes, but that doesn’t work here, so adequate circulation and filtration is a must. Figure on running the entire volume of the pond through the filtration system once per hour. A 5,000 gallon pond should optimally run 5,000 gallons per hour through the filter. Although quality and clarity are totally different issues, with some of the best koi in the world coming out of clay ponds with totally opaque water, that doesn’t work for our ponds. We want to see the koi in polished water, so secondary treatment by ultraviolet light helps keep algae suppressed and water gin-clear. 

Finally, for the healthiest, most vibrant koi, the pond shouldn’t be overcrowded. This is where we have to overcome our own nature, because koi keeping is a powerful addiction. We see an especially beautiful fish and we need to have it. Not only do we always want more of them, but they grow to a pretty impressive size. Forget the four-inch-long cutie you brought home from the pet store. Koi grow to 2-3 feet long and upwards of 30 pounds under ideal conditions, and if they’re happy, they are also procreating like crazy. If you’re not very careful and very disciplined, pretty soon you can walk across the pond on their backs. 

All that said, once you get the bug you’ll never be free of it, so remember these guidelines. 

  • Build It Bigger! The one comment we hear from just about every customer after a couple of years is, we should have made the pond larger and deeper from the start. 
  • Oversize the filtration. The largest skimmer you can install reduces the frequency of emptying the net or basket. The larger the biofilter, the less often you will need to clean it. The less maintenance the happier you will be, and the more filtration, the cleaner and clearer the water. (Plus, you will be able to better support that greater-than-optimal number of fish that you will almost certainly end up with.) 
  • DON’T OVERFEED YOUR FISH, even if they beg, and they will! Too much food means too many nutrients in the water, overloading filtration and vastly complicating maintenance. Also, no matter how much they seem to want to eat, the last thing you want is obese, unhealthy fish. Feed them once a day as much as they can eat in 5 minutes, turning off the pumps to keep uneaten food from accumulating in the skimmer.   

If you’re interested in koi keeping, Atlantic-OASE has everything you need, from kits that make pond construction easy, to advanced filtration that cleans itself and reports back to you via WiFi. You might start by checking out the information at the Atlantic Water Gardens University on our website, and remember, we’re always here to help. Good Luck, and Happy Ponding!

Fun Facts for National Koi Day

In honor of National Koi Day, I thought I’d mention some facts about koi that you may find as interesting as I do.

The term “koi” or “koi fish” is technically incorrect.

That’s right, just like the name of our favorite megamonster Gojira (not “Godzilla”), Westerners got the name wrong. Our finny friends are actually nishiki-goi, colored carp. If you look up the work “koi”, you’ll find the translation is “love”, and the word refers to the physical act, not the Platonic ideal. Oh well, too late to change now, but at least it’s good for lots of overseas giggles.

The fish we call koi have been cultured and bred for so long that their digestive tracts have partially atrophied.

Only about 60% of the food they ingest actually gets digested, one of the reasons they are such prodigious feeders. (And poopers!)

Koi are not only affectionate but intelligent.

They recognize their owner, come when called and can be taught tricks like ringing a bell for food. Our Miss Piggy was with our family for 17 years and knew all of us by our silhouettes and voices. She would race to us when we approached, lifting her head out of the water to be petted, eagerly taking food from our fingers. When she died after a major snowmelt dumped road salt into our front yard pond, we were devastated.    

Barring accidents or predation, koi can live a long, looooong time.

Here in this country 10-20 years is considered a long life; in Japan the average is closer to 50 years, but under ideal conditions colored carp can live for many decades, even centuries. The oldest nishiki-goi on record, a scarlet fish named Hanako (‘flower girl’) was born during the Tokugawa era of shoguns and samurai. Treasured for her unusual color and affectionate nature, her original owners the Koshihara clan built her a spring-fed pond at the foot of Mt. Ontake in the mid 1700’s. In the 60s, two of her scales were taken and analyzed in a lab. Just like trees, scales exhibit growth rings that can be counted to reveal age. The laboratory determined her birth date to be the year 1751, making her 226 years old when she died on July 7th, 1977 (7-7-77)! National Koi Day, July 7 was created in her honor.

Taking Koi Pond Building into the Future

With the new merger between Atlantic and OASE one concern always comes up, “will my OASE pump survive in the bottom of a pond?” 

I completely understand the concern about a pump in the bottom of the pond because traditionally in the US it has only spelled disaster. On the other hand, in Europe they’ve been building ponds for many years this way. They find it weird that the US uses large skimmers and FilterFalls to build our water features. One of the big advantages our company and OASE saw when discussing the merger was the opportunity to change how ponds would be constructed around the world.  

The American way of building ponds is what we’ve typically seen from Atlantic and other companies in the US. We utilize a skimmer to protect our pumps and to pull and trap the debris that floats on the top of the water. From there, the pump pushes water up to a FilterFalls where beneficial bacteria treats the water, removing toxins. But this still leaves one area untreated: we don’t ever touch anything on the bottom of the pond. The black muck that develops on the bottom of the pond has to be removed, typically via draining and mucking out the bottom by hand. Some contractors install bottom drains to easily flush everything out, but whether they pump it out or drain it down, basically they have to do a full restart of the pond year after year.  

The European way has been quite the opposite. They have designed and engineered their pumps to sit at the very bottom of the pond and have them pick up and push fish waste back to a UV/Filtration system that polishes the water. With the fish waste and debris going through the pump up to their filter systems that are cleaning the water, they do not see the need for a FilterFalls. The downside to this is they must use pond nets to clean the debris off the top of the water and are restricted in the types of water falls they can build because their pumps aren’t designed to do high flow at high head heights.  

The A-O merger presents an opportunity to bring both our practices together by incorporating the best aspects of each design. We now are building ponds with a skimmer to pull debris off the top of the water while also allowing us to build great falls using our FastFalls. Then, we are utilizing the OASE “Clear Water Guarantee” system by incorporating their pumps in the bottom of the pond feeding their filters that clean and polish your water. The result is a pond that can be customized to the highest level, cleaning and polishing the water without the need to ever fully drain your pond again. With the OASE PondoVac, we can go in and suck out leaves and debris that settles at the bottom that can’t pass through the pump to get to the filter. As for cleaning the filter, it’s as easy as turning a knob and flushing out the system twice a year, so easy you can do it in a suit and tie.  

And as for concerns about the pump at the bottom of the pond. These pumps are specifically designed to handle everything that a pond throws at it and they’ve been doing it for many years! 

This YouTube video made by a homeowner, who installed a brand new OASE system, shows all the mud and debris that was being put into the filter and how well the system works on day 1!

That is exactly what we want to see happening. It means we are cleaning the pond from top to bottom, unlike in the past when we, here in the States, would only clean from the top. OASE pumps are designed to deliver the debris from the pump to the filter system by utilizing a large intake pre-filter and Environmental Function Control (EFC), which will shut off the pump if it’s running dry or freezes or clogs (which takes a lot), to prevent pump damage. The large surface area of the wrap-around pre-filter allows small particles to pass through. It’s designed for water flow all around the pump, giving it multiple surface areas for the pump to pull water from. The pump also features a coated magnetic rotor for adverse water conditions and a proprietary grounding plate for unparalleled safety. These things make the pump very resilient from ever burning itself out or breaking.  

As Atlantic-OASE continues to grow we want to continue to push the envelope on how our industry creates incredible water features. Our company feels that we have an opportunity to define what a top of the line Koi pond should be built like and give our customers the best possible design available in the industry. We hope you will join us in creating state of the art water features that will be hassle free and allow anyone to enjoy a beautiful pond in their backyard!
