Q: The string algae seems to grow in just a few hours in my stream. What can I do?

Edith – Marion, IN

A: String algae. It seems to just grow and grow, leaving a tangled mess of green slimy stuff in your stream and water garden. Like other types of algae, string algae thrives on sunlight and excess nutrients like fish waste and decomposing organic matter in the water. If you want to get rid of it, check out this five-step plan designed to get your string algae problem under control.

  • Add Plants: Water lilies, water hyacinth, water lettuce and other floating aquatic plants look much nicer than algae, right? These ornamental plants will compete for the food source algae uses for growth, so plant away! A simple rule of thumb is to have 60 percent of your pond covered with submerged, floating and marginal plants.
  • Ration Fish Food: Those pellets and sticks are necessary to feed your finned friends, but keep in mind that fish food adds nutrients to the water in two ways: as wasted food that the fish don’t eat, and as waste after the fish digest it. Monitor how much your fish actually eat and cut back if possible.
  • Pump Up Filtration: If your filtration system isn’t powerful enough to handle your pond’s total fish load, you’ll wind up with burgeoning algae growth and, in worst-case scenarios, lethal levels of ammonia – neither of which you want. Many filters on the market are rated for ponds containing no fish or minimal fish, so get a filter that is rated for at least two times the water volume of your pond.
  • Turn Up Aeration: Beneficial bacteria, like those found in the DefensePAC®, naturally break down fish waste, but they need oxygen to thrive and reproduce. By adding a PondAir™ Aeration System, you’ll boost the oxygen in the water, increase your bacteria levels and reduce the nutrient load, thereby reducing algae growth.
  • Use Oxy-Lift Defense: As needed throughout the season, use Oxy-Lift™ Defense® to lift string algae from waterfalls, streams and rocks. Simply shut down your waterfall, sprinkle the powder directly onto debris-covered areas and watch it instantly start foaming. In 24 hours, it will have removed the algae. Be sure to pull out any debris with a pond net.

String algae may seem like a never-ending battle, but you can manage it with these tried-and-true methods. Good luck!

Why are water changes important? | Decorative Ponds & Water Gardens Q & A

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.

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.

Should I clean my filter media or replace it? | Decorative Ponds & Water Gardens Q & A

Q: Should I clean my filter media or replace it?

Q: Should I clean my filter media or replace it?

Cindy – Dover, DE

A: Those plastic pads, BioBalls™ and Bacti-Twist® that live in your waterfall box, skimmer box and filter unit play a very important role in your water feature. The filter media’s surface is home to millions of beneficial bacteria, which are the biological filtration system in your pond.

Here’s a quick guide that outlines how to care for your filter media – and those tiny microbes.

  1. Clean Infrequently: Once or twice a year, or when your water flow is significantly reduced, inspect and clean your filter media. Rather than scrubbing it spotless with soap or harsh abrasives, gently spray it down with your garden hose, being careful to maintain as much of the beneficial bacteria as possible while blasting away the gunk.
  2. Replace As Needed: If the filter media looks worn on the edges or has gaping holes in it, replace it with some new media, like Matala® Filter Media Pads for extended life and performance, or with our standard reusable 2-inch filter pads, which are perfect for waterfall filters and skimmer boxes.
  3. Seed Some Bacteria: If you need to replace your media, you’ll need to inoculate it with beneficial bacteria. First, test your pond’s water temperature. If the water temperature is 40-50° F, add Pond Logic® Seasonal Defense® to the pond or dump it right on top of the media in your waterfall box. If it’s more than 50° F, seed the filter media with PL Gel and let it set for one to two hours before putting it in your filter unit.

This spring, it’s a great idea to check your filter media and make sure it’s in good working order. Doing so will save you time, hassle and money by getting your pond off to a strong start so you can avoid dealing with insufficient filtration later in the season.

What steps should I do for a spring cleanout? | Decorative Ponds & Water Gardens Q & A

Q: What steps should I do for a spring cleanout?

Q: What steps should I do for a spring cleanout?

Carol – Beaverton, OR

A: Ice melting, sun shining, cabin fever driving you batty … yep, spring must be on its way. For water garden hobbyists, that means one thing: It’s time to head outside and prepare the pond for spring. With some basic planning and a handy-dandy cheat sheet (like this one below), you will have your outdoor oasis cleaned up and ready for fun in no time.

Gather your tools, pull on your hip waders and gloves, and let’s get cleaning!

  1. Evaluate the Pond. The first step is to take a look at the pond and determine what kind of work needs to be done. Did you do a great job cleaning out the pond last fall? Did you procrastinate too long and let those leaves build up? Is it time to give the water feature a top-to-bottom scrubbing?
  2. Minimal Work Required. If you adequately prepped the pond last fall and, after evaluating it this spring, discovered clear water and minimal debris, you’ll only need to do some light cleaning. Scrub the rocks with Oxy-Lift™ Defense®, replace filter pads in the waterfall filter or skimmer box, and perform a 20 percent water change.
  3. Drain Pond, Relocate Your Fish. If a complete cleanout is necessary, you’ll need to drain the pond. Siphon some of the water into a holding tank for the fish, and transport them safely to their temporary home with a pond net. Add some healthy oxygen to the water by submerging and turning on a bubbler or air stone in the tank.
  4. Check Tubing, Remove Debris. While you’re draining the pond, don’t forget to purge the water from the tubing and remove any large debris, like branches or dead foliage, by hand.
  5. Power Wash Away. To remove tough algae growth on rocks, liner and gravel, treat with Oxy-Lift™ Defense® and use a power washer to scrub away the debris if necessary.
  6. Skimmer, Waterfall Wash. Once the dirty water has been drained from the pond, clean out the skimmer and waterfall boxes using a garden hose, spraying away excess muck and buildup. If the filter media looks worn down, now’s the time to replace it.
  7. Check Lighting, Aerator. With the water drained from the pond, you have a perfect opportunity to inspect any underwater lighting fixtures, check the bulbs and clean the lenses – or, better yet, add some new Pond Lighting for dramatic backyard effect. It’s also a good time to check the aerator and make sure it’s working properly.
  8. Reconnect and Reinstall. If you removed and stowed the filter, pump and ultraviolet clarifier last fall, pull them back out and dust them off. Reconnect the plumbing and filters, and reinstall the pumps and UV clarifiers. While you’re at it, change the UV bulbs, too; they need to be replaced once a year for optimal algae-control effect.
  9. Refill, Prep the Pond. Once you’re done with the spring cleaning chores, refill the pond with some fresh water. In addition, be sure to add some Stress Reducer PLUS , which removes chlorine, chloramines and heavy metal from tap water. Then acclimate the fish to the new water and add them back into the pond.
  10. Boost Your Bacteria. Keep the water clean and clear by adding some beneficial bacteria to the pond. Test the water temperature to be sure it’s above 55 °F and add PL Gel to the filter media and Seasonal Defense® to the pond water to help jump start the growth of good bacteria.
  11. Add Aquatic Plants. Finally, be sure to add a variety of pond plants to the water feature. Bog plants beautify the circumference of the pond; floating plants, lilies and lotus provide shade and pops of color; and submerged plants release extra oxygen to the water. They all provide added all-natural filtration and habitat for all underwater pond dwellers.

A spring cleanout may seem like a daunting task, but the time and effort you put into it will pay off with a tranquil backyard oasis. Happy spring!

Why does my pond sometimes turn green in the spring? | Decorative Ponds & Water Gardens Q & A

Q: Why does my pond sometimes turn green in the spring?

Q: Why does my pond sometimes turn green in the spring?

Randy – Huntington, WV

A: After a long, dreary winter, the sight of spring’s green shoots and leaves are a welcome sign – but not in your pond. Green water means algae growth, and that’s not something you want to see flourish. Besides being unsightly, algae degrades your water quality and can actually harm your aquatic pets.

So what can you do to prevent your water garden from turning green?

Add Seasonal Defense®: As long as water temperatures are below 50° F, you can add Seasonal Defense® to your pond. It contains aerobic bacteria that are specially designed for cooler water. When used at this time of year, the waste-gobbling microorganisms will break down dead foliage, fish waste and other sediment that fuel algae growth in your pond.

Keep Up on Your Chores: Make sure you also keep up on your spring cleaning chores because all that decomposing debris feeds algae. Regularly check and clean out your skimmer basket, and remove any leaves or large pieces of debris that blow into the pond with your Collapsible Skimmer & Fish Net. This will encourage the beneficial bacteria in Seasonal Defense® to focus their energy on breaking down fine organic material and muck.

Add Barley Straw Extract: All-natural chemicals found in decomposing barley straw help keep your pond’s water crystal clear. If you add Barley Extract, you don’t have to wait for the straw to decompose. Simply add it to your water according to the label’s instructions and enjoy a clean and healthy water feature. For best results, use Barley Extract in conjunction with Seasonal Defense®.

When is the best time to install underwater pond lighting? | Decorative Ponds & Water Gardens Q & A

Q: When is the best time to install underwater pond lighting?

Q: When is the best time to install underwater pond lighting?

Lou – Winston, OR

A: Whether it’s illuminating a patio, a landscape or a water garden, outdoor lighting can have a dramatic impact on the area’s space. It creates a special mood and spotlights stunning features while adding ambient light to the environment.

Underwater lighting is best installed when your pond is empty, like while it’s being constructed or – in most cases – while you’re doing your annual spring cleanout. If you’re putting in lights this spring, here are four key tips to follow:

  1. Choose the Right Lights: Landscaping lights come in many different sizes and varieties, and so it can be hard to choose the best for your needs. Luckily, we offer three above- and underwater lights that will do the trick.
    • LEDPro™ 6-Watt LED Light Kit: These lights highlight your pond and landscaping with energy-efficient LED bulbs. It shines with the same intensity as a 50-watt halogen but with a longer life span and lower energy costs.
    • LEDPro™ 12-Watt Single Light: This spotlight also features an LED bulb, but it shines with the same intensity as a 70-watt halogen.
    • LEDPro™ Rock Lights: Featuring a realistic stone finish, these small warm-white LED lights illuminate 10 watts per light but use only 2 watts of power. They’re perfect for accenting special features in your garden.
  2. Point Lights to the Pond: Rather than directing your landscape lights toward the patio or other viewing area, shine the light on pond instead. Your goal is to illuminate your water feature – not blind yourself while viewing it.
  3. Cast an Underwater Glow: Beneath the water’s surface, install lights that will spotlight your waterfall or stream’s cascading water. And don’t forget to include some that will highlight landscaping around and pondscaping in your water feature, too.
  4. Stash Extra Power Cord: To give yourself easy accessibility to the underwater lights when you need to change their bulbs, wrap some excess power cord around the light. This will allow you to simply pull the light out of the water and change the bulb without having to drain the water or move a rock.

Over time, algae and other debris will build up on your lights – and so you’ll need to add a new to-do item on your spring cleanout checklist! Each year, plan to give those lenses a good scrubbing and replace any burned-out bulbs.
