If I treat my pond for weeds and it rains, will the treatment still work? | Ponds & Lakes Q&A

Q: If I treat my pond for weeds and it rains, will the treatment still work?

Q: If I treat my pond for weeds and it rains, will the treatment still work?

Amy – Linn Grove, IN

A: That all depends! Because you’re applying chemicals to water, you’d think that rain would have no affect on the herbicide—but it actually might. How long it rains, how heavily it rains and how soon it rained after you applied the treatment could impact its quality and effectiveness.

If wet stuff from the sky is a threat and you’re thinking about spraying algaecides or herbicides to control nuisance plants in your pond or lake, here are four general guidelines to follow:

  1. Check the Weather: Is steady rain forecast for the day? If so, postpone any treatment of emergent weeds. Many treatments need to be absorbed by the plant’s leaves to be effective. A day-long stint of rain will rinse the chemical off the weed before it can be fully absorbed.
  2. Check the Weather, Part II: If you’re expecting heavy precipitation, definitely put off treatment to another day. The applied chemical could rinse off the plants and overflow from the pond before being taken up by the target weed.
  3. Reapply If Necessary: A light sprinkle will generally not affect the chemical’s potency in a pond that’s already been treated. If a downpour occurs within a few hours of application, however, plan to reapply the herbicide in a few days to fully control that target plant.
  4. Make Your Treatment Count: Use a pond sprayer to apply the chemical as close to target weeds as possible, and use a sticky surfactant to help the chemical absorb into the plant like Treatment Booster™ PLUS. Treatment Booster™ PLUS breaks down the surface of the weed or algae and allows the active ingredient to penetrate.

Even though you’re treating aquatic weeds, wet weather can still impact the chemical’s effectiveness. Check the short- and long-term forecast and plan accordingly – because you don’t want all that hard work (and costly treatments) to be for nothing!

I know herons are a common pond problem, but I think I have a raccoon around. Will it eat my fish, too? | Ponds & Lakes Q&A

Matt – Burton, MI

A: Bandit-masked raccoons are a familiar sight just about everywhere because they will eat just about anything, including your fish. Found in forests, marshes, prairies, suburbs and even cities, raccoons can be a nuisance around ponds and lakes. Here’s what you need to know to keep them away from your pond – and your garbage cans.

ID, Please

With the exception of 75-pound Bandit that holds the world record for “World’s Fattest Raccoon,” these nocturnal foragers are typically between 15 to 23 pounds and 30 to 37 inches long, or the size of a small dog. They sport heavy fur streaked in brown, black and gray, and have black eye stripes that resemble a mask. Raccoons have bushy ringed tails that grow up to a foot long, and their dexterous paws and long fingers make distinct prints in the mud or snow.

Sushi for Dinner

Though raccoons love to eat mice, insects, and tasty fruits and vegetables (particularly sweet corn) plucked from your garden and garbage can, the opportunistic water-loving critters will happily take a dive in your lake to hunt for crayfish, fish, turtles, frogs and worms. They’ll use their lightning-fast paws to grab both aquatic and terrestrial prey.

Tracking a Bandit

Raccoons aren’t exactly stealthy. If they’re prowling around, they’ll leave telltale signs around your home and property – like knocked-over garbage cans, overturned rocks and flower pots, rooted-through plants and disheveled yard decor. They’ll also leave tracks in the wet soil around the pond. And, if you’re lucky, you may even find a shelter or den made in a hollow tree, culvert, woodchuck burrow or under a building.

Evicting Raccoons

Mother Nature provides her own raccoon control in the form of coyotes, foxes, great horned owls and bobcats, but you can give her a hand in several different ways.

  • A live-animal trap baited with cat food or tuna will allow you to capture and relocate your problem raccoon.
  • The Nite Guard Solar® deterrent keeps raccoons away with its solar-powered LED lights. Activated at dusk, the red lights resemble a predator’s flashing eyes flash and cause the critter to run away.
  • Keep garbage cans securely sealed and manage other easy-access food sources, like cat food bowls and compost bins.

With hundreds of thousands of raccoons traipsing across the countryside, you’ll likely discover one or two (or an entire family!) living on your property near your lake. But if you use some wildlife management tactics like these, you can keep them under control. Good luck!

We just bought a house with a pond. Do people actually swim in them? | Ponds & Lakes Q&A

Q: We just bought a house with a pond. Do people actually swim in them?

Q: We just bought a house with a pond. Do people actually swim in them?

Julie – Calcutta, OH

A: Yes, absolutely! Swimming ponds are all the rage—and for good reason. Compared to chemical-laden swimming pools cleaned with chlorine, swimming ponds use plants, natural bacteria and aeration to keep the water crystal clear. The Europeans have been creating these for years, and the trend has taken hold here.

Whether you want to dive into your new-to-you pond, however, really depends on how well it has been maintained. Here are some tips to prepare your pond for summertime fun!

  1. Reduce Muck
    There’s nothing like tiptoeing into a pond, only to sink 6 inches into the slippery, slimy muck. Ponds that haven’t been maintained often have a buildup of this sludge. One way to reduce it is to use natural bacteria like MuckAway™. The tiny microbes gobble through the decomposing debris, going through 2″ a month when used as directed.
  2. Add Aeration
    Did your pond come with an aeration system? If not, you need one. An aeration system will increase the productivity of those muck- and odor-eating natural bacteria by infusing the water with oxygen. An aerator will also improve water quality and churn the water column.
  3. Zap Algae
    Algae around your beach area is no fun—and it’s no good for your pond’s water quality, aesthetics and usability. Algae happens, particularly in ponds that have a lot of nutrients (muck and other decomposing debris) and sunshine, but you can battle it with some Algae Defense®. The algaecide goes after chara, filamentous and planktonic algae, the main cause of pea soup-colored water.
  4. An ‘Activity’ Pond
    Rather than refer to your pond as a “swimming pond,” think of the area as your summer activity zone. Who needs summer camp when you can do all these things around your pond:

    • Go fishing! Stock it with fish, grab your pole and tackle box, and catch and release some game fish.
    • Get some exercise! Run or walk laps around your pond, or drop in a paddle boat and do some laps—just 30 minutes can burn 100 calories.
    • Build sandcastles! Why go to a crowded beach when you could build sandcastles at home! Dump a truckload of sand pondside and enjoy your own dunes.
    • Try snorkeling or diving! It may not be the Great Barrier Reef, but you might make some interesting discoveries. Let us know if you find any sunken treasure.

Clare – Westford, VT

A: It sounds like that strange stuff floating in your pond is pollen – particularly if you’ve had the same issue at about the same time in previous years. How do you identify it and get rid of it? Read on to learn more about fixing your pollen problem.

Just on the Surface

Looking like an oil slick floating on top of your pond, the pollen’s hue may vary in shade from white to yellow to green, particularly if there’s a little algae mixed in. The substance will break apart if you run your fingers through it, and it often forms a circle around aeration plates.

The tiny pieces of pollen stay on the surface thanks to something called surface tension. Pollen is light, and when it lands on still water that’s not moving it remains there. Unless something breaks the water tension, like rain or the splash from a fountain, the pollen will continue to float and coat the water surface.

Saying ‘Goodbye’ to Pollen

If you want to get rid of that unsightly pollen, here’s what we recommend:

  1. Add Aeration: Aeration, like our Airmax® Aeration Systems, churns and moves the water below the surface, and that action will help break down the surface tension from the bottom up. We offer a range of aerator sizes to fit any pond, from small ornamental features to large water gardens or fish ponds.
  2. Add Some Splash: While the aerator cycles the subsurface water, a decorative fountain like our AquaStream™ Fountains, or even a garden hose (in desperation!) will break the water tension and dissipate the pollen. Check out the different styles, sizes and spray patterns of our fountains – they look great and work hard!
  3. Wait It Out: Pollen will eventually dissipate with the changing of the season or after a heavy rain. If you’re patient and wait it out, the problem will resolve on its own.

Green Be Gone

Is the pollen in your pond a bit green? You could be battling an algae and pollen problem. In addition to resolving the situation with aeration and a decorative fountain, use Algae Defense®. It’s a fast-acting, algae-killing liquid formula that can be applied directly to your pond with a sprayer – so it’ll destroy the green stuff and dissipate the pollen.

After getting out of my swimming pond, I had a leech on my leg! How do I remove leeches from my pond? | Ponds & Lakes Q&A

Q: After getting out of my swimming pond, I had a leech on my leg! How do I remove leeches from my pond?

Q: After getting out of my swimming pond, I had a leech on my leg! How do I remove leeches from my pond?

Dennis – Blythewood, SC

A: There’s nothing like climbing out of your pond and finding one (or more!) of these little blood suckers stuck to your leg. What are they, and how do you banish them from your pond?

Getting to Know Leeches

Leeches are 2-inch-long brownish-black segmented worms that are a distant cousin to the earthworm. They use their suction cup-like mouths and teeth to latch on to vertebrate and invertebrate animals, feeding on their blood. Of the 700 different leech species, the majority live in freshwater environments, like your swimming pond.

Leeches love to live in the debris at the bottom of your pond. In all that muck accumulation, they get comfortable, find food and hide from predators—also known as fish—swimming overhead.

Despite their bad reputation, leeches aren’t all bad. Up until the 18th and 19th centuries, these worms had been used medicinally on humans to improve and restore blood circulation. The practice waned for a time—likely a combination of the yuck factor and modern medicine—but it’s slowing coming back into favor.

Kicking Leeches to the Curb

Unless you practice leech therapy, you probably want to evict those invertebrates from your pond. The best way to do that is to remove their preferred habitat—all the muck and debris covering the bottom of your pond. How do you do that? Here’s a four-step approach:

  1. Pull Out the Debris: First, use a rake or cutter to remove weeds, accumulated debris, algae, decomposing plants and muck.
  2. Add Beneficial Bacteria: Next, add some beneficial bacteria, like those found in MuckAway™. The bacteria will head to the bottom of the pond and digest whatever muck remains. Remember that it will take some time to break down all that debris, so be patient.
  3. Let Your Fish Do the Work: With nowhere to hide, those leeches will become tasty meals for your fish. You may even consider adding some more leech-eating fish to your pond.
  4. Trap and Destroy: For those leeches that elude your finned friends, you can trap and remove them with a baited trap. Punch leech-size holes in a coffee or aluminum can, bait it with raw chicken or fish heads, and position it in a shallow area of your pond. When the worms go for the grub, they can get in but not out because the burrs from the hole punches will prevent them from escaping. Remove the can once it’s full and repeat until the leeches are gone.

If a leech latches onto you, don’t worry. In most cases, it won’t do any harm. In fact, you might not even feel it as the tiny critter injects the spot with anesthetic-anticoagulant combo while attaching itself with its suckers. You can remove a leech by breaking its suction seal with your fingernail or another blunt object, causing the worm to detach its jaws.

Do I just throw MuckAway tablets into the pond from the shore? | Ponds & Lakes Q&A

Q: Do I just throw MuckAway tablets into the pond from the shore?

Q: Do I just throw MuckAway tablets into the pond from the shore?

Rich – Callahan, FL

A: MuckAway™ does a number on muck. The special blend of aerobic bacteria digests organic debris (a.k.a. muck), improves water clarity and eliminates noxious odors. The precision-release pellets are easy to use, and they’re perfect for battling built-up sludge anywhere in your pond.

But there is a way to best apply MuckAway™. Here’s what we recommend.

  • Disburse Evenly: Whether you’re using MuckAway™ near the shoreline or across your entire pond, the pellets will need to be spread evenly across the treatment area. Plan to use one scoop per 1,000 square feet.
  • Use a Boat: If you are treating the entire pond or lake, consider using a boat for uniform MuckAway™ dispersal. Individual tablets that are spread very far apart (tossed from the shore) will not have as dramatic an impact on muck as those that are densely and evenly distributed.
  • Consider MuckAway™ TL: A large pond or lake may need the super sludge-busting power of MuckAway™ TL Pond Muck Reducer. When used as directed, it will treat an entire surface acre and eliminate 1-2 inches of muck per month regardless of water depth!
  • Combine Forces: Many customers choose to use a one-two punch when contending with water clarity issues. They’ll use PondClear™ Beneficial Bacteria water soluble packets to clean and clear the water column, and MuckAway™ or MuckAway™ TL to break down the sunken muck around often-used areas, like the pond perimeter and beach areas.

You can increase the effectiveness of MuckAway™ and MuckAway™ TL by raking out any large, long-to-decompose debris from the pond before you begin treatments. This allows those aerobic beneficial bacteria to target the fine debris that’s difficult to remove.

Airmax® Aeration is also key to helping your bacteria be more effective at battling muck. The moving, aerated water provides both oxygen and circulation, which creates an ideal environment for MuckAway™ or MuckAway™ TL to flourish. Looking for proof? Check out our Fox Lake Field Study. It shows the results of what happens to muck when MuckAway™ TL and aeration are used together.

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.
