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.

What should I do with my filter media during the winter? | Decorative Ponds & Water Gardens Q & A

Q: What should I do with my filter media during the winter?

Q: What should I do with my filter media during the winter?

Barb – Sterling, CO

A: Your pond’s filter media—the Matala® Filter Media Pads, The Pond Guy® BioBalls™ or Bio-Ribbon that house your beneficial bacteria—will need a little attention going into the winter. You won’t need your filter media during the cold months, but you should inspect it, clean it and purchase replacements parts before you start your water feature up again in the spring. Here’s a rundown of what to do:

Filter Media Pads: Pull out your filter media pads from your pond’s filtration system, waterfall box and skimmer, thoroughly rinse off the debris with your garden hose, and look for frayed edges, holes, large deposits of solid debris or other signs of damage. Plan to replace worn pads as necessary in the spring. You can choose from specially coated Matala® Filter Media Pads, which come in four different densities for your unique filtration needs, or cost-effective rolls of filter media that can be cut to fit and are ideal for waterfall boxes and skimmers.

BioBalls and Other Loose Filter Media: If you use secondary filtration, like The Pond Guy® BioBalls™, Bio-Ribbon, blocks or other loose filtration media that’s kept in a mesh bag, remove it all from your filter or waterfall box after you shut down your waterfall, rinse the bag and its contents thoroughly, and check the bag for holes or worn areas. Replace the bag if necessary in the spring.

After your filter media is rinsed and inspected, you can store them for winter in the filter, waterfall box or skimmer. The filter pads, BioBalls™ and other media will survive just fine outside, even in freezing temperatures. If desired, you can also remove them and stow them inside a garage or basement.

We just had our first freeze. How do I clean up my plants? | Decorative Ponds & Water Gardens Q & A

Q: We just had our first freeze. How do I clean up my plants?

Q: We just had our first freeze. How do I clean up my plants?

Barb – Sterling, CO

A: Brrr! It’s certainly getting cold outside! Your aquatic plants are feeling the chill too, so now is a perfect time to clean them up and put them in a warmer place for winter. So bundle up, pull on your hip waders and Aqua Gloves™ to keep dry and warm, dig out your easy-to-use Pond Scissors and Pliers —and let’s get busy!

Hardy Water Lilies

Hardy water lilies can tolerate cooler temperatures than your tropical varieties, but they need to be kept in a place that won’t freeze, like the deepest areas of your pond. Now that you’ve had your first frost, trim the lilies’ foliage back to just above the root ball and submerge the plants as low as they’ll go for the winter. Come spring, the greenery will reemerge healthy as ever from the plants’ crowns.

Tropical Water Lilies

Tropical water lilies prefer warm temperatures all year-long, so these plants will need to be completely removed from your pond and relocated to a protected indoor space for the winter, like an aquarium or large bucket inside your heated garage or workshop. Check out this article for a step-by-step guide to overwintering tropical plants.

Marginals and Bog Plants

As with hardy water lilies, your marginals’ and bog plants’ foliage will need to trimmed back to just above the soil with pond scissors. Then sink them lower into the deepest parts of your pond where the water remains unfrozen during the wintertime.

Floating Plants

Unless you live in a climate that doesn’t freeze, floating plants like hyacinth and water lettuce won’t survive the winter. Plan to remove them from your pond and toss them in your compost pile. If you leave them in the pond, the dead plants will decompose and cause water quality issues through the wintertime.

Pond Talk: If your aquatic plants are planted in the soil rather than a movable basket or pot, do you do anything special to them to prepare them for winter?

My pond is mostly clean but should I do a fall cleanout? | Decorative Ponds & Water Gardens Q & A

Q: My pond is mostly clean but should I do a fall cleanout?

Q: My pond is mostly clean but should I do a fall cleanout?

Melanie – Ludlow, MA

A: Relax! Unless your pond really (and we mean really) needs it, we don’t recommend doing a total fall cleanout. Doing so would stress your fish out and compromise their health. Any amount of cleanliness you’ll achieve is just not worth the risk.

Instead, here’s a four-step to-do list to prepare your pond for fall:

  1. Get Your Plants in Shape: After the first frost, remove dead foliage from you aquatic plants, trim them back and sink them in the bottom of your pond to protect them from the cold temperatures. If you have tropical water lilies or other temperature-sensitive varieties, make room for them inside your garage or another place that will not freeze.
  2. Remove Algae: If you have a stream or waterfall in your pond, remove any algae or debris with CrystalClear® Algae-Off®, which vaporizes string algae, and Pond Logic® Oxy-Lift™ Defense®, which foams up and lifts debris from surfaces. These oxygen-based products are safe for use around plants and fish.
  3. Clean Up Debris: Using a brush and net, like those included with The Pond Guy® 3-in-1 Pond Tool, scrub down your rocks and liner and net out as much decaying debris as possible. Then use a vacuum, like The Pond Guy® ClearVac™, to suck up whatever’s left. This will minimize the amount of algae-feeding muck decomposing in the pond throughout the winter.
  4. Treat with Beneficial Bacteria: Finally, continue to treat your water garden with muck-munching beneficial bacteria until water temperatures dip to 50° Fahrenheit. Once the water is below 50°F, switch to Seasonal Defense® to continue breaking down any remaining debris. It’s formulated for use during the cooler months.

With these chores completed, your pond will be in good shape going into winter. Until then, relax and enjoy the fall colors and changing season!

My stream is already accumulating algae! Is there anything I can use to help clean it up? | Decorative Ponds & Water Gardens Q & A

My stream is already accumulating algae! Is there anything I can use to help clean it up?

Q: My stream is already accumulating algae! Is there anything I can use to help clean it up?

Kate – Grove City, OH

A: Yep: It’s algae time! As the spring sunshine melts away ice and snow, the sun’s warmth and light reach underwater to give algae growth a little nudge along. When combined with all the extra leaves (also known as algae food!) that have blown in on windy days and a filtration system that isn’t up to snuff with bacteria, they create a perfect environment for algae accumulation.

So how do you get rid of it when water temps are too cold for bacteria and traditional algaecides?

Step 1: Spring Cleaning

If you haven’t already, consider doing a spring cleanout and starting fresh. Check out this blog post for step-by-step instructions for preparing for and giving your pond a thorough spring cleaning. If you’ve already gotten dirty this season, however, and have found that the algae is unwilling to give up its happy home, move on to step 2.

Step 2: Oxy-Lift™ Defense® to the Rescue

For controlling stubborn algae, pull out your Oxy-Lift™ Defense® pond cleaner. The product’s ingredients have no temperature restrictions, so you don’t have to wait for warmer weather to treat the green nuisance. Simply turn off your stream and, while the algae-covered rocks are still wet, sprinkle on the Oxy-Lift™ powder. Let it sit for 5 to 10 minutes. Before long, you’ll see the algae bubble and break free from the rock. Then turn the stream back on, and use a hand net to scoop out the debris or allow your filter to catch it.

Of course, don’t forget to stick to the basics—particularly as pond season kicks off! Keep your filter running and add the natural bacteria once temperatures are suitable to keep algae growth under control.

Q: How do I know it is OK to put my fish back into the outdoor pond?

Ronnie – Salt Lake City, UT

A: This time of year, most of us are suffering with some cabin fever—including your pond fish. After being cooped up all winter long in a temporary indoor aquarium or tub, they’re ready to swim back to their spacious outdoor home.

But before you relocate your fish, you have some work to do first. The best time to return them to the pond is several weeks after you’ve done all the necessary chores to prepare for their homecoming. To make things easy, check out our four-step checklist:

    1. Spring Cleaning: First, clean out your dormant pond. Remove any debris that has settled over the past few months, and perform a thorough spring cleanout to remove winter buildup. This will give your finned friends a nice place to come home to—and minimize algae growth in the spring.
    2. Jump Start Filtration: About a month before you plan to return your fish to the pond, start your filtration system and let it run without fish. Turn on your mechanical filter and seed your filter pads with beneficial bacteria, such as Microbe-Lift® PL Gel, to speed the colony’s growth (but first make sure the water temperature is above 55° Fahrenheit with your pond thermometer). Keep in mind that in the spring, a filter can take four to six weeks to become established, so adding fish without adequate filtration established can result in quick algae formation.
    3. Test Your Water: While your pond is cycling, periodically check your water chemistry with a PondCare® Master Test Kit to ensure the pond water is balanced and pH, ammonia and nitrate levels are safe for fish.
    4. Acclimate Fish: The final step before re-homing your fish is to help them get used to the pond’s water temperature, which will likely be colder than their winter housing. Carry your fish out in a bucket and slowly add water from the pond to the bucket at 10- to 15-minute intervals, using your pond thermometer to check the water temperature as you go. This shock-prevention technique will allow them to adjust slowly—and safely—to their outdoor digs.

Your fish may become stressed during the indoor-to-outdoor transition, but you can keep it to a minimum by preparing their home and making sure they’re as healthy as possible in advance of their relocation. Have fun moving!
