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.

I have a lot of water lilies in my 1/2 acre pond. How do I control them? | Ponds & Lakes Q&A

Q: I have a lot of water lilies in my 1/2 acre pond. How do I control them?

Q: I have a lot of water lilies in my 1/2 acre pond. How do I control them?

Dan – Newnan, GA

A: In ornamental ponds, water lilies planted in pots are prized possessions—but in a shallow farm pond or lake, lilies living wild can be an invasive species that takes over the water surface in no time.

Of course, water lilies aren’t all bad. Their leaves and roots provide food for beaver, moose, muskrat, porcupine, and deer. Their seeds are gobbled by waterfowl, and their leaves provide protective coverage for largemouth bass, sunfish, and frogs. Left unmanaged, however, water lilies can restrict lake-front access, eliminate swimming opportunities and quickly take over shallow areas.

But before we get into how to control these beautiful but troublesome aquatic plants, let’s learn a bit about them.

Habitat, Growth

The water lily is a floating-leaved aquatic perennial herb that grows rooted in mucky or silty sediments in water 4 to 5 feet deep. It prefers quiet waters like ponds, lake margins and slow streams. When unmanaged, the plant tends to form dense areas covering hundreds of acres.

Each spring, new shoots appear from the rhizomes and grow up through the water until they reach the surface. The flowers appear from June to September. Each blossom opens in the morning and closes in the early afternoon for two to five consecutive days. After the flowers have closed for the final time, the flower stalk corkscrews and draws the developing fruit below the water.

The plant over winters underground as the rhizome. These rhizomes, along with the plant’s seeds, are how it reproduces. A planted rhizome can grow to cover a 15-foot-diameter circle in just five years!

Limiting Those Lilies

You can control water lilies with several different methods.

  • Mechanical Control: First, you can cut/harvest the water lilies or dig up the rhizomes to create open areas of water. If you cut the lilies, you must do so several times a year as these plants thrive in shallow water and grow rapidly. If you dig up the rhizomes, it can be an intrusive and costly though permanent process; they can be difficult to dislodge, but it can be done via rotovation (underwater rototilling) or excavation. Either way, mechanical control is a difficult method because the plant will likely regrow from seeds or remaining rhizomes.
  • Chemical Control: Another more effective method is to use reactive chemical treatment, like Shoreline Defense®, to manage lilies that are actively growing and have reached the surface. When applied directly to the foliage—along with some Treatment Booster™ PLUS to break down the plant’s protective surface—the herbicide’s active ingredient penetrates the lily and makes its way to the rhizome. Once it has turned brown, use a Weed Cutter to remove as much of the decomposing plant as possible to prevent an accumulation of dead material and muck. If you use this method, treat your pond in sections, dosing only half of the lilies at a time; if the weather is hot, decrease that to a third or quarter, waiting 10 to 14 days between treatments.
  • Preventive Control: In addition to mechanical and chemical control, you can also prevent—or at least slow down—the growth of water lilies by treating the pond’s water with Pond Dye. By blocking the sun’s rays early in the season, the lilies will not get the light they need to develop.

Controlling water lilies can be a challenge. But these methods, you can manage them and keep them contained in a particular area, making them a beautiful addition to your landscape.

I’ve heard a lot about Clipper Herbicide. What does it do? | Ponds & Lakes Q&A

Q: I’ve heard a lot about Clipper Herbicide. What does it do?

Eldon – Urbandale, IA

A: Clipper™ Aquatic Herbicide controls a wide variety of algae, floating weeds and submerged weeds, but its claim to fame is its ability to wipe out troublesome watermeal and duckweed—two aquatic weeds that can be difficult to manage in any pond or lake. In fact, when used as directed, up to 80 percent of duckweed and watermeal will be eliminated within the first application of Clipper™. Not too shabby!

Here are some tips for use:

  • Check your pH first: High pH levels will reduce Clipper’s™ effectiveness, so test the pH of your pond’s water with a pH Test Kit before using the herbicide. Apply it only when the pH is 8.5 and below.
  • Apply on a sunny morning: The herbicide is a reactive treatment that works better in the sunlight, so treat your pond or lake early in the morning on a sunny day. Hold off on adding light-blocking Pond Dye to your water, until after Clipper™ has had a chance to go to work on the weeds.
  • Spray and play: Applying Clipper™ to aquatic weeds is easy. Simply mix the amount of Clipper™ and water in a Specialty Pond Sprayer according to label instructions, and spray onto floating weeds and algae or place the tip beneath the water’s surface to treat submerged weeds. Over time, the weeds will begin to brown and die.
  • A little goes a long way: You only need to use 1 pound of Clipper™ per surface acre one to two times per year. Because it’s a contact herbicide, complete coverage is essential for effective control. You can reapply Clipper™ after 28 days if you find that you’ve missed some weed patches after the first treatment.
  • No temperature restrictions: Clipper™ can be used year-round in any temperature, but it should be applied only when the weeds are actively growing.
  • Rake away the debris: Once the aquatic weeds are completely dead, use a rake—like the Pond & Beach Rake —to remove the debris. This will prevent the foliage from accumulating and turning into algae-feeding muck.

Clipper™ Aquatic Herbicide can be used in a range of waterways, including bayous, canals, drainage ditches, lakes, marshes, freshwater ponds and reservoirs. It quickly and effectively controls watermeal, duckweed, water lettuce, giant salvinia, cabomba, Eurasian watermilfoil, hydrilla and curlyleaf pondweed. If you fight aquatic weeds in your lake or pond, consider using Clipper™. It’s good stuff!

I fill my pond with tap water. Should I be using water conditioner?| Decorative Ponds & Water Gardens Q & A

Q: I fill my pond with tap water. Should I be using water conditioner?

Q: I fill my pond with tap water. Should I be using water conditioner?

Mary – Sioux City, SD

A: Yes. The water that flows from your hose may be “clean” enough for humans to drink and use for household purposes, but it actually contains a cornucopia of contaminants that can be deadly to fish.

What are some of those pollutants? Besides the naturally occurring ones, like heavy metals and nitrogen compounds in soil, water can contain human-originated contaminants, including bacteria and nitrates from human and animal waste, fertilizers and pesticides, industrial byproducts, and chemicals that actually disinfect and treat the water—like chlorine, chlorinates or chlorine dioxides, according to the EPA.

That’s where water conditioners come into play.

Pond Logic® Water Conditioner removes harmful chlorine and chloramines from your tap water and detoxifies contaminants and heavy metals that may harm your fish. But that’s not all. A conditioner also clears away ammonia generated by the nitrogen cycle and adds essential electrolytes to the water that increase oxygen uptake.

So every time you add city water or hard water to your pond, be sure to add a dose of water conditioner to eliminate those contaminants. In addition, add some Nature’s Defense® . The beneficial bacteria in the additive further reduce ammonia and digest dead organics in the pond, such as phosphates and nitrogen.

To ensure your water is safe for your finned pals, perform regular tests with a Master Test Kit. Designed for water garden and backyard ponds, the kit includes tests for pH, ammonia, nitrite and phosphate.

When should I stock my pond? | Ponds & Lakes Q&A

Q: When should I stock my pond?

Q: When should I stock my pond?

Floyd – Nevada, CA

A: Ahhh … there’s nothing quite like fishing for bass, perch or bluegill from your own private pond or lake. Whether you’re stocking a new pond, replenishing an existing pond after this year’s harsh winter or adding to an already-established population, here’s what you need to know about when and how to best do it.

  • Spring Stocking: Spring is the ideal time to stock your pond with fish. Temperatures are mild and oxygen levels are rising, so the stress factors affecting your fish will be at their lowest. Once acclimated to your pond, they’ll be primed to flourish. Fish can be added in the summer, but they’ll need a little more time to adjust.
  • Remove the Competition: Before you stock your pond or lake with desirable game fish, you’ll need to remove any unwanted wild fish. They’ll negatively impact your new fish population by competing for food and habitat—or they may eat your new fish. Trap them with our Tomahawk Live Trap, which will enable you to relocate them.
  • Happy Habitat: Make a home-sweet-home for your new fish by creating a top-notch habitat for the smaller fish to hide, grow and reproduce. Weeds, grasses, felled trees and other debris already in your pond will provide some cover, but a specially designed environment, like our Procupine® Fish Attractor Spheres, can improve on what’s already there. Just add some ½-inch sections of PVC pipe and the fish will be ready to move in.
  • Healthy Population: Keeping a healthy underwater ecosystem means creating a balanced fish population. We advise sticking to a ratio of three prey fish (like sunfish, bluegill or perch) to one predator fish (like bass) when choosing species. The number of fish you add to your population will ultimately depend on the surface area of your lake or pond. To help you calculate what’s best for your situation, here are some examples of stocking rates.
  • Fatten them Up: With your brood settled in, you want make sure they’re getting enough grub to thrive. A game fish food, like our Game Fish Grower Food, is a great way to provide the fish with protein and nutrients, bolster their immune systems, and grow healthy game fish. Plus, it’s a floating pellet—so you can enjoy watching them as they come to the surface and eat.

Spring stocking time is here! To find ready-to-stock game fish in your area, visit your local fishery. Happy fishing!

Now that it’s spring, when do I start using my DefensePAC? | Decorative Ponds & Water Gardens Q & A

Q: Now that it’s spring, when do I start using my DefensePAC(r)?

Q: Now that it’s spring, when do I start using my DefensePAC®?

Jan – Avoca, NY

A: Containing everything you need to jump start your backyard pond or water garden in the spring, your DefensePAC®” package can be cracked open as soon as the ice melts and water temperatures are consistently above 40°F.

The first products in the pack you’ll use are Oxy-Lift™ Defense® and Seasonal Defense®. They’re perfect for cleaning out your pond and prepping it for spring.

  • Oxy-Lift™ Defense® lifts debris from waterfalls, streams, rocks and anywhere else muck collects in your pond. Simply shut down your waterfall and/or streams, sprinkle on the affected areas and watch the foam get to work breaking down that unsightly buildup. Use Oxy-Lift™ Defense® only when needed.
  • Seasonal Defense® contains hungry beneficial bacteria that will immediately get busy gobbling through leaves, scum and settlement that have collected over the winter. Spring applications should begin at pond startup or just after ice melts. Use Seasonal Defense® once a week for four weeks in the spring.

The other ingredients in DefensePAC®—including Nature’s Defense®, Clarity Defense® and Muck Defense®—all work to promote a healthy ecosystem, clean and clear the water column, and break down organics in your pond. They can be used on a routine basis throughout the spring and summer.

  • Nature’s Defense® contains natural bacteria that breaks down organics in your water garden. These organics, if left alone, are a food resource for algae—which is not something you want to feed. Because it works best when temperatures are above 50°F, check you water’s temperature with a Floating Pond Thermometer before dosing. Use Nature’s Defense® every two weeks throughout the season.
  • Clarity Defense® is designed to clarify ponds. It locks up excess nutrients, making them unavailable as a food source for algae, and settles suspended particulates that are in the water column. It also stimulates natural bacteria growth and buffers pH levels.
  • Muck Defense® also contains natural bacteria that accelerate the decomposition of organic matter caused by rotting leaves, algae and fish waste. This is great for water gardens that were constructed with rocks and gravel that are difficult to vacuum. We suggest using Muck Defense® every four weeks throughout the season when water temperatures are above 50°F.

DefensePAC® is a five-step solution to cleaning and clearing your pond—and keeping it that way all season long.

Q: The temperatures are rising, so when do I start using my ClearPAC PLUS?

Sharon – Waynesboro, GA

A: Inside your ClearPAC® PLUS box, you’ll find everything you need to keep your lake clean and clear this spring and summer. The five components, when used as directed, address the root of the most common pond problems by tackling excess nutrients and shielding the water from algae-feeding sunlight.
When should you start using ClearPAC® PLUS? It all depends on your water temperature. Let’s take a closer look at when and how to best use the products in your super-pack.

  • Pond Dye: As soon as the ice melts on your pond or lake, add your Nature’s Blue™ Pond Dye. The dye is not temperature-sensitive so it can be used even when water temps are too cold for beneficial bacteria products. Pond Dye does more than color your water and add to your landscape’s aesthetic; it also shades it from sunlight, which can kick-start algae blooms as the mercury rises.
  • PondClear™ and MuckAway™: When water temperatures rise to a consistent 50°F, you can start using the beneficial bacteria found in PondClear™ and MuckAway™ to break down nutrients suspended in your water column and muck on the bottom of your pond. These products can be used at the same time as your Pond Dye and EcoBoost™.
  • EcoBoost™: This bacteria booster that has no temperature restrictions, so it can be used year-round to bind phosphates that find their way into your pond or lake. You can use EcoBoost™ throughout the spring to give you a head start on pond season.
  • Algae Defense® : To be used only as needed, this algae-destroyer treats troublesome floating filamentous algae, bottom growing chara and the planktonic algae when it’s green and growing. Use Algae Defense® when the water temperature in your pond or lake is above 60°F. Don’t use Algae Defense® if you keep koi or trout in your lake.

After treating your pond with ClearPAC® PLUS, don’t forget to remove dead algae and debris with your Pond & Beach Rake. Doing so will remove the decaying vegetation and prevent them from feeding the algae—which will ultimately help your Pond Dye, PondClear™, MuckAway™, EcoBoost™ and Algae Defense® work even better!
