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.

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

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.

Jason – Brooklyn, NY

When it comes to filter media, your pond – and the fish and plants that call it home – benefit from variety. Because each type of filter media provides different benefits to your pond’s water quality, each one plays a vital role, and none should be overlooked.

The characteristics of different filter media say a lot about the roles they play. For sheer durability, you’ll appreciate the performance of our Matala Filter Media Pads and our Pond Logic® BioBalls Filter Media. Our Matala Pads are available in multiple densities – from porous to fine – and they’re designed for easy cutting to fit the dimensions of your filter. These filters perform well for the long haul, with the most porous Black Matala Filters designed to remove larger particulate, ranging to our Grey Matala Filter Pads, which filter small particles. With a careful mix of Matala Filter Pads, you’ll achieve both mechanical and biological filtration, and your pond water will be cleaner, clearer, and healthier for all of your pond’s inhabitants.

Our BioBalls provide excellent secondary filtration by providing a home for beneficial bacteria. These bacteria perform vital biological filtration functions, and their unique design is well suited to fit filter boxes. They’re easy to clean, and they last virtually forever.

Our Fusion Filter Media Pads, which are available for purchase by the foot, allow for maximum water pass-through without sacrificing durability. Because of their unique design, they’re exceptionally clog-resistant, and they’re easy to cut to suit the needs of your filter.

Finally, our Bacti-Twist® Bio Ribbon Filtration Media does the twin tasks of biological and mechanical filtration. This distinctive media provides a large surface area to house beneficial bacteria, and fits easily into any filter container.

With a carefully-selected mix of filtration media – of varying densities to allow for water flow and the establishment of beneficial bacteria, both you and your pond will see the short- and long-term benefits, making your water feature a picture of health and cleanliness, with minimal effort.

Matt – Howell, MI

For pond enthusiasts who are short on free time, we’re big fans of pondless waterfalls. Since they typically don’t have fish and don’t involve open bodies of water, there’s very little to maintain. Without fish waste, debris or muck to contend with, these beautiful features can add a lot to your yard – and require very little in return.

Occasionally, though, algae can form on rocks in in a waterfall. And unless you have a fondness for the green stuff, you’ll want to dispatch with it as quickly and efficiently as possible.

For some, biological filtration is a viable option. Since most pondless waterfalls rely on a basin for circulation, the installation of an appropriately-sized filter – and some filter media – will generally resolve any algae issues. But under the circumstances, filtration is rarely the simplest solution. At the Pond Guy, we strongly recommend the use of PondLogic® Oxy-Lift™ Defense® Pond Debris Remover. Oxy Lift™ is designed to break debris off rocks quickly and easily – without a lot of effort.

In fact, process couldn’t be much easier. Simply turn off the waterfall, sprinkle on Oxy Lift (be sure to avoid direct contact with any plants), and let it sit for ten minutes. If the algae are particularly well-established, light brushing can help to loosen things up. Once those steps are complete, simply turn the waterfall back on – and get the instant gratification of immediate results.

As an added measure to prevent recurrence of algae, a partial water change and an occasional basin cleaning goes a long way. So enjoy the limited free time you have. Your waterfall is waiting.

Should I add submerged plants to my Water Garden? | Decorative Ponds & Water Gardens Q&A

Stacey – Grand Rapids, MI

Let’s face it: floating and surface plants, like lilies and hyacinths, are the rock stars of any water garden. They’re the show-offs, the preeners, the colorful ones that visitors “ooh” and “aah” over; the divas that pond owners proudly feature on center stage.

But, may we ask, where would the rock star be without his support crew – the techies, the roadies, the groupies? Still playing air guitar in front of his mirror, that’s where. Lilies, hyacinths and the like just happen to be the most visible and attractive feature of a supportive ecosystem that should include their plainer relatives – the Submerged plants, like Vallisneria, Red Ludwigia, Hornwort and Parrot’s Feather. These worker plants compete with algae for the nitrogen produced by decaying plants and fish waste,produce oxygen to help keep the pond properly aerated,andprovide shade and shelter for koi and other fish. Submerged plants may not be flashy, but they’re a critical component in maintaining water quality and general pond health.

The easiest way to add one of these workers to your water garden is to plant its stems in a Laguna Submersible Pond Planting Basket along with an ample supply of Microbe-Lift Aquatic Planting Media, and place it on the bottom of the pond. The baskets come in various sizes with mesh sides and bottoms – this allows the plant to seek nourishment outside the basket, without the risk of growing out of control.

Any performer will tell you that a well-fed support crew is a happy support crew. So to make sure your Submerged plants are getting the nutrition they need, we highly recommend the Laguna Temperature Activated Aquatic Fertilizer Spikes, a verbal mouthful that also delivers the goods. Simply push a spike into to the soil near the plant until the cap is just above the surface and you’re all set for a year.

So, by all means, add Submerged plants to your water garden and let your lilies rock on!

My pond water is green. Do UVs really work? | Decorative Ponds & Water Gardens Q&A

My pond water is green, do UV’s really work?

My pond water is green, do UV’s really work?
Summer – Baton Rouge, LA

The short answer? Yes. While it might seem like smoke and mirrors, UVs help to consolidate algae particles, which are then removed through regular filtration. And because planktonic algae particles are typically responsible for green pond water, products like our all-in-one ClearSolution Filter and AllClear systems – which include UVs within their filters – and our Power UV™ Clarifiers – which can be added inline with your existing plumbing – are terrific resources to help keep pond water clear and clean. Bear in mind, though, that UV can’t work miracles, and has no impact on string algae.

Now that we’ve established the fact that UVs really do work, there’s an even bigger issue to consider. The presence of planktonic algae is, after all, a symptom of a larger issue – and UVs are simply a means to treat it. In order to reduce reliance on UVs and filtration, it’s important to consider the cause of the bloom.

Planktonic algae bloom in nutrient-rich water. Nutrients can come in a variety of forms. There are many culprits – including excessive fish food, an overabundance of fish (and the waste they produce), bird droppings, and even runoff from fertilized lawns. When too many of those nutrients are in your pond, algae – which are present in all water – multiply quickly to take advantage of what they see as a free lunch. When algae multiplies, a cycle begins which depletes oxygen, and can harm or kill both fish and beneficial aquatic plants. So take stock of your pond. Evaluate the number of fish you have – and adjust your feeding levels accordingly. If your pond is overpopulated, consider reducing the number of fish, and the corresponding waste they produce.

Finally, consider using our PondLogic® DefensePac®, which helps to improve water quality, eliminate muck and built-up debris, and to enhance fish health. With quick and easy application, you’ll see noticeable results in no time – and with minimal effort.

Robert – Racine, WI

Waterfalls are one of nature’s greatest creations. In addition to providing breathtaking beauty and places for daredevils to kayak and – for some inexplicable reason – ride over in padded barrels, they serve as massive aeration systems, introducing fresh oxygen into the ecosystem that fish and plants need to thrive. In backyard ponds, waterfalls serve many of the same functions – but their scale is often inadequate to provide sufficient aeration. They also fall a bit short as places for kayakers and barrel riders to strut their stuff.

So, while your backyard waterfall definitely helps to keep water oxygenated, additional aeration is always helpful – especially when algae begins to grow, and fish are faced with warming water and reduced oxygen levels. To provide the aeration any backyard pond needs, we strongly recommend our KoiAir™ and PondAir™ Aeration Systems. With a wide variety of options available for ponds of every size and depth, these systems help to increase circulation and reduce stratification to provide the healthiest possible environment for fish and decorative plants.

For signs that your pond’s aeration is insufficient, look for increases in muck and debris at the pond bottom. When properly aerated, muck is broken up naturally, leaving the bottom clean and the water clear. If you have fish, and they surface regularly or gather beneath a waterfall, your aeration may be inadequate. If that’s the case, you’ll give your fish cause for celebration by installing additional aeration – and you’ll have the satisfaction of a clean, clear pond that makes your backyard the perfect sanctuary.

Q: How many and what type of plants should I have in my pond?
Bryce – Myrtle Beach, SC

If you’re a person – and we’re going out on a limb here to assume you are – you understand the importance of eating a balanced diet of fruits, vegetables, grains and proteins. Variety, it seems, is more than just the spice of life. Like you, your water garden thrives on variety – in the form of a carefully selected mix of aquatic plants. But just as overeating is harmful to you, over-planting spells trouble for your pond. So, whether you’re dining or planting, it pays to be prudent.

Ideal plant coverage is around 60% of your featured surface – this allows for enough nutrient absorption to help prevent algae from gaining a foothold in your pond. There are many types of water plants to choose from – bog plants, marginal plants, lilies, floating and submerged plants – and frankly, we recommend that you try and use them all because each type of plant brings a little something different to the water table if you get our drift.

For instance, submerged plants, like Hornwort or Anacharis, are oxygenators, providing critical support to a pond’s eco-system by supplementing the water with oxygen, while floating plants, like the water hyacinth, provide shade that cools the water and cover under which fish can hide.

Our customers have found The Pond Guy Choice Hardy Water Lilies, make lovely additions to their ponds. Position the root of the plant in a container of Microbe-Lift Concentrated Aquatic Planting Media, and locate the water lily so that its floating leaves are away from any splashing water for best results.

Blue Flag Iris, Water Hibiscus and Bog Bean are all lovely examples of bog plants that can be placed around the shallow edges of your pond for both aesthetic and ecological reasons. To keep your water garden in healthy, we suggest you treat your plants once a year to such products as the Laguna Temperature Activated Aquatic Plant Fertilizer Spikes or the nitrate and phosphate free supplement Bloom and Grow, formulated specifically for aquatic plants.

There’s no doubt about it: variety is the spice of life. It’s also the sign of a healthy, well-cared for pond.
