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!

If I can’t do a big spring cleanout on my pond, what is the best way to get the debris out of the pond? | Decorative Ponds & Water Gardens Q & A

Q: If I can’t do a big spring cleanout on my pond, what is the best way to get the debris out of the pond?

Q: If I can’t do a big spring cleanout on my pond, what is the best way to get the debris out of the pond?

Maggie – Amherst, OH

A:  An annual spring cleanout is an important chore when you own a backyard pond. It’s when you remove all the decaying organics that collected over the winter, trim back dead foliage, kick on your filtration and aeration systems, and generally spruce things up around your water garden wonderland.

But what if your pond was well-sheltered and protected from leaves and debris, or you live in a temperate climate where a total pond shutdown was unnecessary? Or what if you simply don’t have time to dedicate to all that cleaning and maintenance?

Well we have some shortcuts for you. Though it may be better in the long run to do a thorough cleanout at the start of the season, these five tips will cut down the time it takes to do your spring chores.

  1. Do a Partial Water Change: To help remove some floating and suspended debris, do a partial water change. Let 10 to 20 percent of your water drain from the pond, and add fresh water along with some The Pond Guy® Stress Reducer PLUS to remove heavy metals and prevent your fish from getting too stressed.
  2. Add Some Shine: Oxy-Lift™ Defense® will quickly shine up your waterfalls and shoreline rocks. It’s simple to use: As you’re doing your partial water change, sprinkle Oxy-Lift™ Defense® on scum-covered rocks, streams and liner before you refill your pond. In just 24 hours, you’ll see the gunk break free with no scrubbing at all!
  3. Vacuum Debris: Use your ClearVac™ Pond Vacuum to easily suck up gunk, sludge and decaying organics on the pond bottom. It has four different attachments – gravel, string algae, narrow and wide – along with extension tubes, so you can vacuum almost any surface. For debris larger than 3/8 inch, simply pull out your Collapsible Skimmer and Fish Net and scoop it out.
  4. Add Seasonal Defense®: To break down debris that your pond vacuum missed, add some Seasonal Defense® beneficial bacteria to the water. The microorganisms, which are designed to work in cooler temperatures, will break down leaves and sediment that have collected over the winter. It also kick-starts your pond’s biological filtration system, priming it for summer.
  5. Rinse Your Filter Media: Finally, remove your filter media and give it quick rinse with your garden hose to break up and wash away any accumulated gunk. No need to scrub it too thoroughly; the bacteria living in the pads or BioBalls™ will come back to life once temperatures rise.

Of course, for a truly healthy pond, we still recommend a complete cleanout. We’ll describe those chores in depth over the coming weeks. But for now, this quick fix will get the debris out of your pond, giving it a facelift for spring soirees.

What’s the best way to get debris off the rocks when I clean out my pond this spring? | Decorative Ponds & Water Gardens Q & A

Q: What’s the best way to get debris off the rocks when I clean out my pond this spring?

Q: What’s the best way to get debris off the rocks when I clean out my pond this spring?

Jake – Grand Junction, CO

A: There’s nothing like spring cleaning – especially when it gives you a chance to remove some of that icky, slimy scum and debris that’s been growing on your waterfall, rocks and gravel all year-long. With the water drained from your pond (after your fish are safe in a temporary tub), you have easy access to those hard-to-clean spots. Here’s our two-step solution to scrub everything clean.

Step 1: Power Wash
Without a doubt, power washing with a pressure washer or high-pressure nozzle is the quickest way to blast debris off larger rocks and features. Once your pond is drained, and you’ve removed large debris and trimmed away dead plant material, start power washing from the top and work your way down, being careful to avoid growing plants and curious frogs. Some of that debris contains viable beneficial bacteria, so it’s OK to leave a little behind.

Because all that stuck-on debris is easier to remove when it’s wet, start power washing as soon as possible after your pond is drained. Believe us: It’s harder to clean off that debris once it’s dried out and crusty!

Step 2: Oxy-Lift
Next, use Oxy-Lift™ Defense® to lift and remove tough debris on larger rocks, waterfalls and streams by pouring it directly on the trouble spots. While you’re at it, sprinkle some on the smaller rocks and hard-to-power-wash gravel, too. You will instantly see it start to foam and remove stuck-on scum. After about 10 minutes or so, hose everything down, drain the dirty water and debris, and repeat as necessary; it might take a few cycles for a thorough clean-out.

After your pond is spick and span, your rocks and gravel are in place, and your plants are repositioned, fill it back up with water and add a chlorine remover or Stress Reducer Plus to condition the water and make the freshly cleaned aquatic environment safe for your fish. While your filters and pond are being reestablished with beneficial bacteria, keep your finned pals on a light spring diet.

What does it mean when you say a pond must “cycle” before adding fish? | Decorative Ponds & Water Gardens Q & A

Q: What does it mean when you say a pond must “cycle” before adding fish?

Q: What does it mean when you say a pond must “cycle” before adding fish?

Sherry – Raleigh, NC

A: The term “cycle” refers to the nitrogen cycle – and it’s an important process to understand if you plan to keep fish in your pond. The nitrogen cycle provides the biological filtration in the water, which keeps the water free from toxic compounds created by decaying organic matter. The process is a complicated one, so here are the basics.

Nitrogen Cycle 101

Before we discuss cycling a new pond, let’s dive into how the nitrogen cycle looks in an established, mature pond. As organic material – like uneaten food, dead plant matter and fish waste – decay, the bacteria that break it down release ammonia, which is toxic to living organisms. One particular microorganism called nitrosomonas, however, loves ammonia. It feeds on ammonia and oxygen, and releases a chemical called nitrite.

Nitrites are also dangerous to fish and aquatic critters, and so another group of microorganisms – nitrobacter – enters the nitrogen cycle picture. These bacteria transform nitrites into relatively harmless nitrates, which are then absorbed by algae and plants or reduced by water changes.

New Pond, New Bacteria

A new pond doesn’t have healthy populations of nitrosomonas and nitrobacter yet, and so the pond must be “cycled.” This refers to establishing and maturing your pond’s biological filtration system so that it’s able to turn ammonia into nitrates. To do so, you need to start the process with an ammonia source (a few hardy fish) and seed the pond with these beneficial bacteria, which can be found in Pond Logic® Seasonal Defense® and in Microbe-Lift® PL Gel.

Nurturing Nitrosomonas

In the early spring when established ponds are waking up after a long winter, a similar cycling process will take place. Some nitrosomonas and nitrobacter will survive in your filtration media and gravel and begin to colonize, but it’s a good idea to give them a boost. Pond Logic® Seasonal Defense® is formulated for use in cooler temperatures – making it perfect for early spring applications. Since those microorganisms live in your filtration media, avoid washing it when you’re doing your spring cleaning.

Cycled and Ready for Fish

The cycling process can take four to six weeks, though in the warmer spring and summer this time may be reduced. Keep an eye on your ammonia, nitrite and nitrate levels with a test kit, like our API® Pond Master Test Kit. Once it indicates that nitrates are present, your pond is considered cycled. Add only a few fish at a time to prevent ammonia levels from spiking again.

Keep in mind that this ammonia-nitrite-nitrate cycle is always occurring, so test your pond regularly to ensure the health and wellbeing of your finned friends.

I’ve used lava rock in my filter for years. Are bioballs really that much better? | Decorative Ponds & Water Gardens Q & A

Q: I’ve used lava rock in my filter for years. Are bioballs really that much better?

Q: I’ve used lava rock in my filter for years. Are bioballs really that much better?

Dana – Altadena, CA

A: The media you use in your filtration system matters. Just think about its purpose: To house billions of beneficial bacteria and other microorganisms that keep your pond alive, crystal clear and algae-free. Thanks to their ample surface area, both lava rock and bioballs will work, but bioballs have some benefits over the rock. Read on to learn more.

Lava Rock’s Limitations

Lava rock – that igneous rock that’s formed as an erupting volcano’s molten lava cools and hardens – is very porous. When chunks of it live in your filtration system, you’re providing a lot of surface area for those beneficial bacteria to colonize and grow. That’s what makes it such a great filter media.

It does, however, have its drawbacks.

  • Clogged Holes: Over time, the porous rock can become easily clogged with muck and debris. Once the holes and pockets are clogged, they can become very difficult to clean out – which ultimately creates less overall surface area.
  • Hard Water: Lava rock naturally contains a variety of minerals, including iron and magnesium, that could affect your water’s pH, making it harder. Hard water could make it more difficult to treat algae that forms.
  • It’s Heavy!: They may be porous chunks of rock, but hefting bags of it takes some strength – particularly when its wet and full of gunk.

Benefits of BioBalls

Bioballs, like The Pond Guy® BioBalls™ filter media, are plastic spheres made up of dozens of thin rods that provide plenty of surface area for beneficial bacteria to thrive. Two hundred of the bioballs in a mesh bag will filter about 1,000 gallons of water in a pond with minimal fish.

Compared to lava rock, bioballs have some definite benefits.

  • Easy to Clean: Bioballs can also become clogged, by they’re easy to clean. Just rinse them off with water from your pond and you’ll be good to go.
  • Indefinite Lifetime: Because they’re made from long-lasting material, bioballs will not degrade and will function equally well year after year.
  • Shape Shifters: The bioballs’ round shape allows them to more easily conform to any filter, no matter its shape.
  • Lightweight, Easy to Handle: Each one of these tiny, 1 1/2-inch plastic spheres weighs a scant 0.3 ounces; 200 of them weigh a whopping 3 1/2 pounds. They’re easy to deposit and remove from your filter thanks to a mesh filter bag.

Consider making the switch from lava rock to bioballs. You’ll see better results and you’ll need to do less maintenance. What’s better than that?
