We just bought a house with a half-acre pond. Where do we start? | Ponds & Lakes Q&A

Q: We just bought a house with a half-acre pond. Where do we start?”

Hans – Brandon, MS

A: Some home buyers look for granite countertops or in-house movie theaters – but a half-acre pond is an amenity that makes us giddy! Because you likely don’t know the history of the pond, how it was built or how it was maintained, it’s best to give that new pond a complete rehab from the bottom up so you can use it to its full potential.

Here’s a five-step process that will make the job easy:

  1. Assess the Pond’s Condition. Before you begin rehabbing your pond, take some time to examine it, including measuring its size and depth, identifying weeds and beneficial aquatic plants, checking for fish, and inspecting pre-existing structures like a dock or an aeration system. These details will help maintain your pond or get it back into shape.
  2. Give It an Oxygen Boost. Your real work begins with installing a bottom-diffused aeration system, like one of the Airmax® Aeration Systems. The units, which include a diffuser, compressor and airline, circulate oxygen throughout the water column so that it’s readily utilized by critters living in your pond, including fish, frogs and beneficial bacteria. It also helps remove harmful gases from the water. If your pond already has an aeration system, thoroughly inspect all its parts and tune them up as necessary.
  3. Control Weed Growth. Treat prolific growth of aquatic weeds and algae. Invasive plants like cattails, chara, phragmites, bulrush, watermilfoil and even out-of-control water lilies can become real problems in a closed ecosystem. Depending on your situation, you may need to use an herbicide and/or algaecide to get them under control before they take over and negatively impact your water quality. For help, check out our Weed Control Guide, which can help you ID and choose the right remedy for the weed.
  4. Remove Unwanted Vegetation. Before and after you treat the weeds and algae, mechanically remove growing and dead vegetation with a Weed Razer™ and Weed Raker™. If you don’t pull that growth out of the water, it will break down into detritus and pond muck, which will actually fertilize the weeds and algae you’re trying to eliminate!
  5. Do Your Maintenance Chores. Now that your pond is on its way to being clean, clear and usable, keep it that way by maintaining it with beneficial bacteria and pond dye. Beneficial bacteria, like those found in ClearPAC® PLUS Pond Care Package, will break down any residual pond muck buildup and keep the water clear. Pond dye will tint the water blue or black, preventing ultraviolet rays from reaching problem plants like algae while adding beauty to your waterscape.

With a little work, you can transform your new pond into a dramatic part of your landscape – particularly if you decide to add a decorative fountain or other feature to it. Have fun with your new aquatic playground!

Does the type of algae and where it’s growing determine what chemical is needed? | Ponds & Lakes Q&A

Q: Does the type of algae and where it’s growing determine what chemical is needed?

Q: Does the type of algae and where it’s growing determine what chemical is needed?

Pete – Addison, AL

A: When battling algae, you have the upper hand if you understand the enemy. What type of algae is it? How does it behave? What are its strengths and weaknesses? Before we get in to how to treat the green menace, let’s discuss the different species of algae and where you are likely to find them in an aquatic ecosystem.

Algae Explained

In a large pond or lake planktonic algae, filamentous algae and chara, are the most common types of algae you’ll come across.

  • Planktonic algae, the source of algae blooms, are floating, microscopic plants that color pond water shades of green, blue-green, brown or variations in between. In controlled amounts, this type of algae can actually be beneficial. It can shade the pond’s bottom, preventing subsurface nuisance plants from growing.
  • Filamentous algae are single-celled plants that form long, visible chain, threads or filaments. These threads, which start growing along the bottom of the lake in shallow water or on rocks or other aquatic plants, intertwine and form mats that resemble wet wool. When these mats rise to the surface, they’re commonly referred to as pond scum.
  • Chara is a gray-green branched multicellular algae that has 6 to 16 leaf-like branchlets that grow in spirals around the stem. Though bottom-growing chara superficially resembles terrestrial plants, it lacks flowers, true leaves and roots. It has a skunky, musty, garlicky-type smell and has a crunchy- or grit-type texture, thanks to calcium carbonate deposits on its surface.

In general, algae will grow just about anywhere sun penetrates the pond. Surprisingly, algae has some benefits: The tiny plants feed fish and make great homes for micro- and macro-invertebrates like bugs and worms. But algae has its definite drawbacks. Besides being unsightly and odorous, uncontrolled blooms can cause oxygen depletions, affect fish health and, in extreme circumstances, cause fish to die.

Vanquishing the Menace

The key to successfully treating algae – whether planktonic, filamentous or chara – is to make the most contact between it and the algaecide. Rather than dumping the chemical into one place in the pond, which will only kill algae in that small area, it needs to be evenly dispersed.

Floating mats of filamentous algae and suspended planktonic algae are best treated with liquid mixtures, like Algae Defense® and Clipper™, that are sprayed directly over the area with a pond sprayer. To treat extra thick mats, stick the top of the sprayer into the mat itself to get the chemical to the deeper portion of the problem.

For bottom-growing algae, use granular algaecide, like Cutrine®-Plus Granular and Hydrothol, and distribute it with a granular spreader. It’s the preferred choice because the granules will sink over the algae bed and make maximum contact with it.

Follow up by raking out any decaying or dead debris with the Pond & Beach Rake, setting up an aeration system and adding natural bacteria, such as the types found in ClearPAC® PLUS Pond Care Package.

My pond was a mess, so I drained and refilled it. Now I have algae. What do I do? | Decorative Ponds & Water Gardens Q & A

Q: My pond was a mess, so I drained and refilled it. Now I have algae. What do I do?

Beth – Benton, AR

A: Sometimes it’s just easier to start from scratch – particularly if you have a disaster in your pond.

A complete water change rids your water feature of excess organic waste, clears up murky water (briefly, as you’ve discovered) and gives you a chance to start over with a clean slate. Those are some worthy benefits!

The urge to purge, however, has its drawbacks. If you’ve completely drained the water from your pond and scrubbed everything clean, you’ve also stripped a lot of the beneficial bacteria that was working to help clean the pond in the first place! The algae that’s growing now is most likely due to fish waste and a lack of mature filtration.

To return your pond to its crystal-clear state, here’s what we recommend.

  1. Decide how bad it really is: Believe it or not, some algae in your pond is natural and beneficial as it helps filter the water. Make sure your expectations are in line with the reality of having a pond, and then let the pond take its natural course with a little help from you. But be patient! The Nitrogen Cycle will eventually help clear things up naturally – but it takes time. If your water quality begins to suffer a few weeks in, think about doing a partial water change and/or following these additional suggestions.
  2. Treat if necessary: If the algae is becoming excessive, treat the algae growth with an algaecide in the morning or evening when water temperatures are cooler. In addition, make sure you have adequate aeration to ensure oxygen levels stay high for your finned friends.
  3. Seed Your Filter Media: To kick-start the regrowth and reproduction of beneficial bacteria in your pond, add some DefensePAC® to your pond and filter. The package contains Nature’s Defense®, which instantly begins breaking down dead organics in the pond; Clarity Defense®, which helps clear debris suspended in the water column; and Muck Defense®, which attacks buildup on the liner, rocks and gravel.
  4. Condition the water: When you refill your pond with water, be sure to use Stress Reducer PLUS to condition the water and reduce fish stress. It helps your fish form a beneficial slime coat that’s lost from stress or handling, and it also makes tap water safe by working to remove chlorine, chloramines and heavy metals.
  5. Learn from the situation: Instead of letting your pond fall into its “mess” state again, figure out why it wound up in that situation in the first place. Are there too many fish living in your pond? Is your filter too small for your pond’s volume and fish load? Do you need more plants growing in and filtering the water? Does your pond receive too much sun or rain runoff? Dig down to the root cause of the problem and correct it!

In the future, if you find your pond’s water quality waning, consider doing a partial water change instead of a complete water change. A little fresh water will go far to clear things up without having to start completely over!

Q: I spend a lot of time trying to kill algae, and sometimes it doesn’t work. Do you have any tips?

Vince – Columbia City, IN

A: Frustrating, isn’t it? You spend hours upon hours pondside, dosing the water with algaecides and raking out algae-feeding plant matter and detritus, only to see the green menace return weeks – if not days – later. Is there a way to control the nuisance algae that’s turning your pond into pea soup?

You bet. Below are our top recommendations for battling the algae. If you follow these guidelines, you’ll have that green menace under control in no time.

#1 – Treat Only Actively Growing Algae
When using algae control products in your pond or lake, the algae must be present and actively growing. Why? Because the chemicals need to make direct contact with the tiny organisms and absorb into their cells for them to be effective; if there’s no living algae, the chemicals will land in the water and become diluted, and therefore ineffective when the green stuff blooms.

#2 – Treat When Weather Is Favorable
Algae can grow in cold temperatures – even frigid, depending on the species – but algaecides aren’t so tolerant. The pond water must be warmer than 60°F for the chemicals in them to work. Apply your algae treatment on a sunny, mild day when rain is not expected in the immediate forecast. This will allow the chemicals to adequately absorb into the algae. As always, read the product label for instructions and specific temperature requirements.

#3 – Treat Only a Third at a Time
When temperatures heat up and the algae dies off, that combination of warm water and decaying plant matter reduces the amount of oxygen available to fish and other living critters in the pond. Keep them in an oxygen-rich environment by treating the pond in small sections and wait 7-10 days before moving to the next section. In addition, keep your aeration system or fountains running during treatment to continue circulating and oxygenating the water.

#4 – Read the Product Label
Different algaecides have different active ingredients, inert ingredients and specifications, so always read your product’s label for appropriate protective equipment and application rates. Pay special attention to warnings concerning water use and restrictions in ponds used for irrigation, drinking and swimming, as well as in ponds that house certain types of fish. If you have trout, which are sensitive to copper-based treatments, test the carbonate hardness levels and ensure they are above 50 ppm prior to treatment. If they’re above that, use another treatment, like Hydrothol®, that contains no copper.

#5 – Follow Up with Airmax® Ecosystem Pond Management Program
Algaecides are a great tool that can temporarily clear up pea soup water, but they do little address the actual problem causing the algae – which is excessive nutrients and organics. By following your treatment up with proactive pond management practices, such as aeration and natural water treatments like MuckAway™, you will reduce the accumulation of dead organic material, which will help to keep your water clear season after season.

How are algae able to grow in the winter when everything else is dormant? | Ponds & Lakes Q&A

Q:How are algae able to grow in the winter when everything else is dormant?

Q: How are algae able to grow in the winter when everything else is dormant?

Patrick – Vandalia, IL

A: Algae can be tough little buggers. An estimated 72,500 algal species exist worldwide, and some of them can thrive in inhospitable conditions, including areas with ice and snow. With a handful of nutrients and a little bit of light, they’re able to grow – even in the 39 degree water under the ice in your lake.

But if your lake’s water is clean and clear during the spring and summer, how can it explode with algae in the winter?

Food Aplenty

Algae feed on byproducts of decomposing organic debris, like phosphorous and nitrogen, in the water. During the warmer months, natural bacteria would typically break down these nutrients, leaving little food for the organisms. But in the cooler months, those bacteria go dormant. That means the algae enjoy a feast – and a population explosion.

If you keep a hole in your lake’s ice, you can help control the nutrient density with a product like Pond Logic® EcoBoost™. This bacteria enhancer, which has no temperature restrictions, binds suspended organics while providing trace minerals to fish. Simply mix it with water and pour it into the lake.

Let There Be Light

Algae also require sunlight to thrive – but not much. Even through a clear, solid sheet of ice, algae can get enough light to use for photosynthesis. When that light is impeded, however, the algae won’t grow as quickly.

A layer of thick snow cover is Mother Nature’s way of preventing light from penetrating the water, but you can also use pond dye, to block those rays. The blue or black dye comes water soluble packets that are simple to use: Just toss two packets per acre into the lake, and the shade will inhibit algae growth.

Algae’s Benefits

Believe it or not, algae growth in the winter does have its benefits. It helps to filter the water, and on warmer days it’s a great snack for your fish. Plus, when the algae photosynthesize, they give off oxygen as a byproduct – which is then available for your fish (and other aquatic critters) to breathe.

Don’t worry: The algae won’t take over your pond like it does in the summer. It can grow, but the cold temperatures aren’t ideal for explosive outbreaks. If you’re concerned, however, try some EcoBoost and Pond Dye. They’re safe for your fish, and they’ll keep that algae under control until spring.
