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!

Are there different steps for treating a pondless waterfall versus a pond? | Decorative Ponds & Water Gardens Q & A

Q: Are there different steps for treating a pondless waterfall versus a pond?

Debbie – Johnston, RI

A: Easy care is one of the most attractive features of a pondless waterfall, particularly for those who have a penchant for ponds but no time to perform routine maintenance on them. You get all the benefits of a water feature—the sound of running water, the added aesthetics in your garden space, even the plants and wildlife that it attracts—but you don’t have to deal with those pesky seasonal chores.

As ideal as they are, pondless water features do require some attention. Here are three simple steps to keep your waterfall looking its best:

1. Keep Your Water Clean and Clear

With no body of water, your pondless feature may not require you to remove muck, fish waste, decomposing leaves or other collected pollutants, but you still should keep the water looking clean and clear. Plan to periodically add some beneficial bacteria, like those found in Liquid Clear™, to gobble through any fine debris that may discolor your water or feed algae blooms.

2. Remove Buildup from Your Rocks

Rocks and other surfaces in your pondless waterfall will no doubt become breeding grounds for string algae and other debris, so take time to remove any buildup with an algaecide, like Algae-Off® String Algae Remover or Oxy-Lift™ Defense®. These fast-acting solutions use the power of oxygen to lift and wash away accumulated algae and muck. For best results, plan to turn off your system’s pump to ensure the powder contacts every surface, restarting it after the product has time to work.

3. Check Your Water Levels

Because the water basin is hidden, you can’t always see how much water there actually is in your pondless waterfall. To prevent your pump from drying up, make sure you periodically check the reservoir — or, better yet, add an auto-fill valve, like the PondBuilder™ Automatic Water Fill Kit, that will refill any water lost to splashing or evaporation. It’s easy to install and can be adapted to any garden hose, ½-inch irrigation line or vinyl tubing.

If things have really headed south, try performing a partial or complete water change along with using some beneficial bacteria. They will get you—and your pondless waterfall—back on track and ready for summer enjoyment.

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.

Is there an ideal temperature to treat algae?

Is there an ideal temperature to treat algae?

Crystal – New Baltimore, MI

It depends what you mean by the word “treat.” If you’re looking to throw a party in its honor, pretty much any temperature will do – because algae grows all year ‘round, even during the winter months. But if you’re hoping to give it the kind of treatment that makes it feel extremely unwelcome, you’ll see the best results when water temperatures are at 60 degrees Fahrenheit or higher. When water is warmer, algae tends to thrive. Because it’s thriving, it’s feeding – making it much more susceptible to algaecides.

Because very few of our customers express interest in enhancing algae growth, we’ll assume most readers are in the latter category. And if you are, we have a variety of highly effective options to accomplish your objectives. Algae Defense® with Treatment Booster™ PLUS is among our safest, most effective weapons in the battle against algae. Algae Defense® is a fast-acting aquatic algaecide, and it’s highly effective at eliminating a broad spectrum of pond algae. By including Treatment Booster™ PLUS, which breaks down algae’s natural defenses, this combination packs a particularly effective double-whammy, and makes short work of offending algae blooms.

For spot-treatment of algae growth, we also recommend Cutrine®-Plus Granular . Formulated to make quick work of both surface and bottom-forming algae, this safe, powerful algaecide does double-duty by both killing existing algae, and inhibiting its future growth.

While some pond owners prefer to eschew algaecide and rake algae out manually, the raking-only approach requires much more maintenance and attention. Algae are extremely hearty, and raking leaves trace amounts in the pond, allowing for recurrent blooms. For longer-lasting impact, the ideal treatment includes the use of algaecides, followed by cutting with our weed cutter, raking with our Pond & Beach Rake, and follow-up treatment with natural bacteria to break down any remaining muck.

Give your algae the treatment they deserve before temperatures start to fall – and start next season with a leg up on their plans for next year’s invasion.

Does Having Too Many Koi Cause String Algae? – Water Garden & Feature Q & A

Water Gardens & Features Q & A

Q: I have a bad case of string algae in my water garden and someone told me it was because I had too many fish. I have an approximately 1,000 gallon water garden and around 40 koi 6″ long in it. Is that really too many? If so, how many should I have? – Marco of Texas

A: You can ask anyone here at The Pond Guy; usually the first question we ask when someone says they have a bad algae problem is, “How many fish do you have?”, followed by, “What size water garden do you have?”. 9 out 10 times, there are way too many fish in the water garden. So why does having that many fish cause algae? Let me explain.

Sunlight + Food Source = Algae: Algae really only needs two things to grow, sunlight and a food source. The food source can come from many sources but fish waste is a major contributor. This means the more fish you have, the more waste, the more algae. Make sense?

Finding a Balance: When you put fish into your water garden always consider the future. Small fish become big fish and fish are very romantic creatures. Let’s say you purchased 20 koi at around 3″ each. Your pond may be able
to handle the fish load for a few seasons then all things start to change. As time went by, your fish have grown and maybe even started a family. As nature takes its course, your pond starts to pay the price and water quality becomes an issue. Take into consideration that 40 1″ fish produce the waste of just one 12″ fish. So even though you pond may have been able to handle the fish load in the past, you must consider that your fish load or fish waste grows expotentially every year.

Koi vs. Goldfish: I know that when you’re shopping for fish koi are more expensive and sometimes the goldfish look really nice too. I feel the same way myself at times. Just keep in mind that goldfish can reproduce up to 6 times a year where koi only reproduce once a year.

Fish Tips: Goldfish can grow up to 18” long and live up to 20 years, where as a koi can grow up to 36” long and live over 200 years! One famous scarlet koi, named “Hanako” (c. 1751 – July 7, 1977) was owned by several individuals, the last of which was Dr. Komei Koshihara. Hanako was reportedly 226 years old upon her death. Her age was determined by removing one of her scales and  examining it extensively in 1966. She is (to date) the longest-lived koi fish ever recorded (wikipedia).

How Do I Combat String Algae in my Water Feature? – Water Feature Q & A

Water Feature Q & A

Q: I have a 1,000 gallon pond and already the string algae is starting. I am sick of constantly cleaning it. Any ideas? – Steve of New York

A: Like Steve many of you find yourselves in this same situation, where it seems like you are battling algae year after year with no end in sight. The thing I want you to know is that in order to fully understand how to control algae, you really have to understand how it develops in the first place.

The Key Ingredient:
One of the key ingredients for algae to grow is a food source (aka Nitrates). And I’ll have to say in almost every water feature that has a bad algae problem, it is the abundant fish load that is causing the issue. So why does an abundant fish load cause algae? When fish eat they over time, like every living creature, will have to excrete the waste (aka ammonia). This ammonia, when filtered properly, will breakdown into nitrates (aka food source). Make sense so far? This food source is then eaten by algae. From there some of the algae will be eaten by the fish and thus the cycle, the nitrogen cycle of life, begins again.

So the bottom line here is: If we have control of the food source (aka Nitrates), we have control of the algae. I have mentioned this before in the past, but it bears repeating.

Keep Fish Loads to a Minimum:
I know you love your fish and this is a touchy subject. But if you plan to have sixty 12″ koi in a 1,000 gallon pond, your going to have an algae problem and it won’t be inexpensive to get a hold of. When calculating your fish load think of it in pounds of fish or total inches. For example, one 6” fish can weigh as much as four 4” fish. The number of fish will affect the overall fish load, although 10 small fish may only produce the waste of one large fish. With this said, remember that your fish are growing and in many cases multiplying. Always plan for the future and be careful not to overstock your water feature.

Proper Filtration:
The size and type of your filtration system will depend on your total fish load. If your filter is not properly sized for max potential, your fish will outgrow the filter. When this happens, ammonia levels can reach to lethal levels. In most cases filters on the market are rated for ponds containing no fish or a minimal fish load. It is always best to get a filter that is rated for at least 2x the water volume of your pond.

Aquatic Plants:
Aquatic plants and algae will compete for the same food source in order to grow. I don’t know about you, but I would much rather see a few beautiful water liles then green slime. A simple rule of thumb is to have 60% plant coverage. This should consist of submerged, floating and marginal plants. Floating plants, such as Water Hyacinths & Water Lettuce, are fantastic at pulling nitrates from the water. I recommend putting a few into your waterfall filter box if you have one. Rooted plants, such as water lilies and marginal plants, create a great place for your fish to hide from predators. Please note when aquatic plants are not present, algae will take their place. See our selection of aquatic plants here.

Beneficial Natural Bacteria :
I’m sure you hear this a lot nowadays as to why you should be adding beneficial natural bacteria to your water feature. The reason is because it is another reducer of nitrates. One  product to check out for this is called the DefensePAC®. It is a combination of five products that provide beneficial bacteria, trace minerals, and a fish and plant safe pond cleaner. The DefensePAC® works to breakdown fish waste, leaves or other organics that accumulate in the pond. These are essential to maintain a clean, clear and healthy ecosystem. The best of all, one DefensePAC® lasts up to 6 months for a 2,000 gallon water feature.
