Q: Why are water changes important?

Q: Why are water changes important?

Shirley – Warr Acres, OK

A: It’s nice to open a window on a warm spring day and let the fresh air flow through your house, right? Well, a partial or complete water change in your koi pond or water garden is the same thing: It freshens your finned pals’ environment, making them happy and healthy.

Here are five reasons why water changes are so important to your fish, plants and other aquatic life:

  1. Nutrient Removal: Muck and debris buildup happens in just about every water feature. A water change manually removes any excess nutrients and chemicals like nitrates, phosphates and ammonia that can be harmful to fish and other underwater critters.
  2. Healthy Fish: Fresh, clean water means improved water quality, which ultimately promotes your fishes’ health. Just as you need oxygen to thrive, your fish need clean water to thrive. Their well being is directly related to the liquid environment in which they live.
  3. Algae Control: Pea soup and string algae feed on all that decomposing waste, which they use as fertilizer. By removing those excess nutrients in the water column with a water change, you can discourage the growth of algae.
  4. Fights Foam: Foam forms when excess organic material has accumulated in your water garden. When this nutrient-laden water pours down your waterfall, the air and water collide, causing the proteins and other organics to be trapped inside bubbles rather than turning into ammonia and nitrites. A water change will quickly reduce that foamy buildup.
  5. Clears Water, Stabilizes pH: A water change will also improve the appearance of cloudy water and maintain pH levels, resulting in a pristine pond filled with healthy fish, lush greenery and clean water.

To keep stress levels down among your fish, we recommend doing partial water changes as soon as water temperatures reach 50° F. In addition, be sure to add some Stress Reducer PLUS and LiquidClear™ to your water. The Stress Reducer PLUS forms a beneficial slime coat on your fish and makes tap water safe for them. The LiquidClear’s™ beneficial bacteria helps to digest dead organics in the water, making it crystal clear.

Why does my water garden turn green and can I prevent it? | Decorative Ponds & Water Gardens Q & A

Q: Why does my water garden turn green and can I prevent it?

Laurie- Bardstown, KY

A: Green water in fish ponds and water features are a common conundrum faced by hobbyists. What causes it, and how can it be fixed?

Algae Explosion
Green water is the result of an imbalance in your pond’s ecosystem. When too many nutrients – also known as decomposing plant material, fish waste and other debris – build up in your water garden, algae flourish because the nutrients act like fertilizer to those tiny plants. That thriving planktonic algae is what causes your water to resemble pea soup.

Finding Balance:
To achieve balance in your pond, you need to evaluate and correct the underlying problems that are causing your green water. Here’s a guide that can help you identify the problem and work toward a solution:

  • Problem: Too many fish.
    Solution: If your water garden is brimming with fish, it may be time to relocate some of them. Overcrowding is a common source for green water because your filtration system may not be large enough to handle the amount of waste being produced. A simple rule of thumb to ensure room for your fish is one fish (5 inches long) for every 10 square feet of surface area.
  • Problem: debris buildup.
    Solution: After a long winter, waste and debris may have built up in your pond. A good spring cleanout will remove those excess nutrients that are feeding the algae. Here’s an easy step-by-step spring cleaning guide to follow that will help you through the process.
  • Problem: Inadequate mechanical filtration.
    Solution: Mechanical filtration helps to remove the excess nutrients from the water column. As the water passes through the filtration system, debris is removed and collected in the filter box or skimmer. Check to be sure your filtration system is adequate for your pond’s size and fish population. If it’s not, consider giving it a boost.
  • Problem: Lack of beneficial bacteria.
    Solution: Beneficial bacteria, like those found in DefensePAC®, are microorganisms that eat through detritus and other algae-feeding nutrients. With little or no nutrients to feed the algae, the green stuff will eventually die off. Learn more about DefensePAC’s components and how to use them here.
  • Problem: Inadequate aeration.
    Solution: Those beneficial bacteria – as well as your pond’s fish – need life-giving oxygen to thrive, and that’s where aeration comes into play. Air being pumped into the water via a diffuser or air stone will circulate the water column and infuse the water with oxygen. Learn more about the importance of aeration here.
  • Problem: Too much sunlight and not enough plants.
    Solution: Because algae are plants, sunlight is essential for growth. You can block that sunlight by covering your water’s surface with floating plants. We recommend shading 40 to 60 percent of your pond with water lilies or other floating plants.

Going Ultraviolet
Once you’ve cleaned out your pond, checked your filtration and aeration systems, added some beneficial bacteria, adjusted your fish load and added some plants, you should be well on your way to clearing up that pesky algae. A final remedy to try is an ultraviolet clarifier, like The Pond Guy’s® PowerUV™ Clarifier. It’s designed to clear water. As a result, the tiny particles of debris clump together and are removed by your mechanical filtration system.

Good luck keeping that green water at bay!

How often should I be changing my UV bulb? | Decorative Ponds & Water Gardens Q & A

Q: How often should I be changing my UV bulb?

Q: How often should I be changing my UV bulb?

Deborah – Providence Forge, VA

A: Your UV bulb is an important component of your pond’s filtration system. The bulb’s ultraviolet rays destroy the ultra-fine planktonic algae that cause green water by destroying the plant’s cellular walls. The tiny dead algae particles are then removed by your mechanical filtration system, leaving behind clean, clear water.

UV Ready

For maximum effectiveness, you should change your UV bulb at least once a year, such as when you perform your pond’s annual spring cleanout. If you’ve recently changed your bulb and your water is still turning pea soup green, you might need to simply clean off debris that has built up on the bulb itself.

Whether you have a standalone UV clarifier, like the PowerUV™ or one that’s part of a filtration system, like our ClearSolution™, use a soft cloth when cleaning or changing the bulb rather than using your bare hands. The oils on your skin can actually shorten the lifespan of your bulb.

Unfortunately, a UV clarifier does not affect string algae at all, so you’ll need to use AlgaeOff® or AlgaeFix® to rid your pond of it. But if your pond turns green from planktonic algae every year from full sun exposure or too many fish, a UV clarifier is an excellent solution.

Preventing Algae Growth

Though UV bulbs do a great job with green water, an even better solution is to prevent algae growth in the first place. Planktonic algae flourishes in ponds that have nutrient-rich water—meaning water that has lots of fish waste, leftover fish food, decomposing plant material and even fertilizer from your lawn.

You can tamp that green growth down by reducing the number of fish in your pond, minimizing the amount of food you feed them and cleaning up the waste they produce, as well as regularly removing the built-up detritus.

Consider using the Pond Logic® DefensePAC®, which uses beneficial bacteria to improve water quality throughout your water column, eliminate muck and built-up debris, and enhance fish health. With quick and easy application, you’ll see noticeable results in no time.

Should I add a pressurized filter to my water garden? | Decorative Ponds & Water Gardens Q & A

Q: Should I add a pressurized filter to my water garden?

Q: Should I add a pressurized filter to my water garden?

Sherri – Hilliard, FL

A: Whether you have an existing pond or are building a new one, just about any pond can benefit from a pressurized filter.

Able to be positioned anywhere outside your pond, these units hold water pressure so filtered water can be routed back to the pond or up to a waterfall. This allows you to create a flowing waterfall effect without taking space at the top of the falls.

But that’s not all. Here are some more reasons to add an AllClear™ PLUS Pressurized UV Filter to your water feature:

  • Remove Excess Fish Waste: Are your koi and goldfish getting bigger and adding to the waste load in your pond? Instead of parting with a few of your finned pals, just add another filter! It will help to reduce the added waste from the growing fish and allow you to keep them part of the family.
  • The Backflush Feature: Water changes can be a pain. Pulling out a pump and routing water out of the pond for your regular water changes take time and effort. But with the backflush feature on the AllClear models, the hard work is a snap! You simply turn a dial, and waste water and debris are rinsed from your filter via a discharge outlet.
  • Green Water Abated: In addition to featuring mechanical and biological filtration, the AllClear filters include an ultraviolet light, which destroys algae and clears up green water. If you experience algae blooms throughout the pond season, a UV light will help.

With some things in life, too much isn’t always a good thing—but that’s not the case with filtration. As long as you’re not filtering out your beneficial bacteria, more filtration will only make your water clearer and pond healthier.

PRO TIP: If temperatures dip below freezing where you live, the AllClear PLUS will need to be removed for the winter and stored in a frost-free area.

Q: Besides koi, what are some other types of fish for my pond?

Judy – N Tonawada, NY

A: Koi may be the living jewels of the pond world, but you can choose from a variety of fish that are suitable for your water garden – most of which can be found at your local pet store. Some of our favorites include:

  • Comets/Sarasa: Colorful and active, these varieties of goldfish are distinguished from their aquarium cousins by their long, single and deeply forked tail fin. In optimal conditions, their tails can grow up to 2 feet in length! Comets typically have red and white coloration with red appearing on the tail and dorsal fin. The Sarasa’s color pattern, in fact, often resembles a kohaku’s, making it quite koi-like. These guys have a life span of 7 to 14 years or more.
  • Shubunkin: Another variety of goldfish, shubunkins sport opalescent red, white, grey, black and blue scales in a calico pattern – and the bluer, the better (according to fanciers). They have streamlined bodies with well-developed and even fins. Shubunkins, which hail from Japan, reach a length of 9 to 18 inches and live 7 to 14 years or more. They add a big splash of color to your pond.
  • Plecostomus: Why not put your fish to work for you! The plecos is an omnivorous fish that will actually eat your string algae (as well as leftover fish food and other scraps). In a pond, sucker fish can grow up to 2 feet long. Because he is a tropical fish, he will need to be overwintered inside when water temperatures dip below 60° Fahrenheit because he’ll die in temperatures below 55°F.

As temperatures start to dip in the fall, it’s a great time to add new fish. Just make sure you have the necessity on hand to acclimate them. You’ll need Pond Salt, which will reduce the fishes’ stress, improve their gill function and protect them against common pond toxins while adding essential electrolytes to the water. You’ll also need Stress Reducer PLUS, which forms a protective slime coat on your new fish, and removes chlorine, chloramines and heavy metals from tap water. For more tips for acclimating your new fish, check out our blog post here.

So many fishes, so little time … With all these fabulous finned friends to choose from, you’ll wish you had a bigger pond!

My water garden has turned green. Will a UV light help my pond? | Decorative Ponds & Water Gardens Q & A

Q: My water garden has turned green. Will a UV light help my pond?

Al – Mount Holly, NJ

A: Ultraviolet bulbs can work wonders in an algae-filled pond, particularly one in full sunlight. As the green water passes by the light, concentrated UV rays damage the tiny plants, ultimately killing them.

UV clarifiers work well and can certainly help your pond, but they shouldn’t be your primary method of algae control. Before investing in a UV unit, check your mechanical and biological filtration first.

Mechanical Filtration

Did you perform a thorough spring cleanout of your pond? Is your filter overloaded with debris? Do you need to wash out or replace your filer pads? Is the system sized appropriately for your pond? You may need to make some filtration upgrades. The Pond Guy® AllClear™ Pressurized UV Filter adds mechanical and biological filtration as well as a UV clarifier, giving you three types of filtration in one unit.

Biological Filtration

In addition to checking your mechanical filtration system, you should also make sure you’re following a regular maintenance routine by adding Nature’s Defense® and Muck Defense® to your pond. A healthy population of beneficial bacteria—your biological filtration—will keep the nutrient load in check, which will starve the algae out of your pond.

UV Clarifier

If your mechanical and biological filtration are taken care of and your water is still too green to enjoy your koi and goldfish, consider a UV light. Here are some tricks for choosing the right one:

  • Wattage: The first trick to getting the best results is to pick a UV bulb that has a high enough wattage for your pond’s volume. All UV clarifiers are rated based on pond size. The larger the wattage, the larger the pond size the UV clarifier can handle.
  • Flow Rate: The second trick is to pump the water past the bulb at just the right flow rate. Pushing water past the UV light too fast can render it ineffective, while pushing the water too slow can cause the UV clarifier to act like a sterilizer, killing not only algae but your beneficial bacteria as well. A great rule of thumb is to push the water approximately half of what the UV is rated per hour. For example, The Pond Guy® 9-watt PowerUV™ Ultraviolet Clarifier is rated for ponds up to 1,200 gallons, so a 600 GPH pump would be ideal.

Another point to consider: Do you want an above-water UV clarifier, like the PowerUV™, or a submerged one? If you’re looking for a below-water model, check out the Pondmaster® Submersible UV Clarifier. It includes a Halo Ring that lights up to show you the unit is working.

Why Does My Pond Water Turn Green? | Decorative Ponds & Water Gardens Q & A

Why Does My Pond Water Turn Green? Why Does My Pond Water Turn Green? 

Joanne – Evans City, PA

Green water is a form of algae called planktonic algae and there are quite a few factors causing your water to be clear during the winter and green as the weather warms up. The main reason is the interruption of the nitrogen cycle.

In order for algae to grow, it needs a food source (nutrients) and sunlight. During the colder winter months of the year, nutrients within the water are less likely to increase due to the fact that the digestive systems of fish have slowed to a point where little, if any, nutrients (fish waste) are being added. Also, during the colder months, algae and aquatic plants are not as active at consuming nutrients.

As the weather warms up, fish become active, digestive systems kick back in and nutrients begin pouring in and if not held in check using aquatic plants, natural bacteria and filtration, green water will develop.

If you have chronic green water and still can’t keep it in check, consider a UV or Ion clarifier.

Monica – Chicago, Il

In the world of water features, disappearing fountains are in a category of their own. Because they don’t involve fish and plants – and typically don’t have filter systems – many people assume they’re maintenance free. But like all backyard water features, disappearing fountains do get dirty, and often gather debris that aren’t eliminated through simple recirculation.

As a result, disappearing fountains are susceptible to water discoloration caused by debris buildup. Fortunately, Pond Logic® FeatureFix™ Water Feature Cleaner is formulated specifically to safely eliminate accumulated debris and clear unsightly discoloration – often in as little as 48 hours.

To prevent ongoing buildup problems, a disappearing fountain is a prime candidate for regular maintenance. We recommend the regular application of Pond Logic® FeatureClear™ Bacterial Water Feature Cleaner, which contains natural, beneficial bacteria that digests organic debris to keep water crystal clear. It’s true. Disappearing fountains do require regular maintenance. But with FeatureFix and FeatureClear, it’s one item on your “to do” list that’s downright easy to check off.

When you create a new pond, you’re effectively building a new ecosystem from scratch. At the beginning, your pond’s waters might look clean, clear and inviting, but nature’s just getting started. Until the initial nitrogen cycle is complete, there’s still work to be done before fish can safely take up residence.

At its early stages, any new body of water – whether an indoor aquarium or a backyard pond – goes through the nitrogen cycle. This cycle begins when living organisms break down nitrogen through their natural digestive processes. Until that cycle is complete, concentrations of ammonia naturally build up in the water – and too much ammonia is extremely harmful to fish. Fortunately, with the introduction of natural bacteria in products like ourPond Logic® DefensePAC® to your pond, you can speed up the nitrogen cycle, making the pond safe for new fish in four to six weeks or less.

In addition to DefensePAC, other products like Pond Logic® Stress Reducer Plus and Pond Logic® Water Conditioner go a long way toward making new pond water inhabitable. Stress Reducer Plus helps fish to restore their natural protective slime coats, making them less vulnerable to illness. Water Conditioner helps to neutralize chlorine and other chemicals in the water that can lead to stress.

But simply adding DefensePAC, Stress Reducer and Water Conditioner won’t tell you when your water is ready to support piscine life. For that, you’ll want to use our PondCare Master Liquid Test Kit, which tests water for pH, ammonia, and nitrite. When readings are consistently within healthy ranges – as clearly explained in the Master Liquid Test Kit’s documentation – you’re ready to welcome your new fish to their new home.

I empty my skimmer every day. Is there a better way to keep leaves out of my pond? | Decorative Pond & Water Garden Q&A

I empty my skimmer every day. Is there a better way to keep leaves out of my pond?
Joseph – San Francisco, CA

Leaves are notoriously difficult to train. Try as you might, they simply fall wherever they please. And when their drop zone of choice is your pond, the task of cleaning them out quickly loses its novelty. Fortunately, there are lots of ways to keep even the most determined leaves out – and cleaning your skimmer on a regular basis is just the beginning.

For those who experience limited leaf drop in their pond, a skimmer may do the lion’s share of the work by gathering up the majority of floating leaves and debris. For any surplus, and for leaves and debris that sink to the bottom of the pond, hand nets and vacuums may be sufficient to keep your water clean and clear.

But not everyone enjoys the satisfying sense of accomplishment that comes with manual leaf removal. If you’re one of those who don’t, we strongly recommend the use of pond netting to stop leaves before they reach the water. At The Pond Guy, you’ll find plenty of options. For economical, single-season purposes, try our Dewitt Economy Pond Netting. For a more durable option that stops leaves and debris, keeps predators at bay and allows abundant light penetration, consider our Clear Fine Mesh Pond Netting. For durable protection that will provide years of use, the nylon mesh construction of our Premium Pond Netting is an exceptional value.

For the ultimate in pond protection, though, our Nycon Big Top Pond Cover is a natural choice. Designed to prevent penetration by even the smallest debris – while keeping predators out – this durable cover forms a tent over your pond, and will provide years of seasonal service.

However you choose to preserve your pond’s pristine appearance, timing is of the essence. As soon as leaves start to fall, it’s time to take action. And whether you’re skimming, cleaning or covering, we have everything you need to make the job a breeze.
