Jason – Raleigh, NC

Duckweed can be a real nuisance if not identified and treated correctly. As it is a prolific grower it can quickly make your pond or lake look more like a golf course in a relatively short period of time. Duckweed is a small floating weed with a single root hair extending from the bottom of each individual leaf. Each green leaflet is about 1/8” of an inch in size and you should be able to fit about 5 to 10 on the tip of your finger. Duckweed can sometimes be confused with watermeal which is also a small green floating weed. Watermeal differs from duckweed in that it is much smaller and has a grainy or almost sandy feel to it if you hold it in your hands.

You can treat duckweed with two different methods. The first method is by spraying contact herbicides like Pond Logic® Pondweed Defense™ or Redwing™ directly onto the floating masses with a pressurized tank sprayer. This method typically yields fast results but tends to be a quick fix that ends up resulting in new growth reforming over just a few weeks. If you need to whip your pond into shape for a planned day or two event, then spraying your pond with a contact herbicide may be an appropriate treatment for you.

For longer lasting control of duckweed you can treat the pond with WhiteCap™ aquatic herbicide. This product works by inhibiting the plants ability to produce carotene and as a result chlorophyll is degraded by the sunlight and the weed dies. There are however a few things you will need to check before adding it to your pond to ensure a successful treatment. Most importantly, WhiteCap™ has a 30 day irrigation restriction meaning that if you water your plants or grass with your pond water you will not be able to do so for at least 30 days. Secondly, Whitecap needs to maintain a high concentration in the pond for up to 90 days. If your pond is prone to overflow or has an inlet/outlet chances are that the WhiteCap™ will rinse out of your pond to quickly making the treatment less effective. A good way to visually check your water loss is to color the water body with pond dye. Dye will typically remain in your pond for 2-4 weeks in normal conditions. If your pond looses color sooner then it is a great indicator that too much water is exiting the pond.
As WhiteCap™ is degraded by sunlight it is important that you dye your pond while you are chemically treating the water body. When applying WhiteCap™ use a pressurized tank sprayer and submerge the spray nozzle to apply the herbicide beneath the surface of the pond where it is safe from evaporation and sun exposure.

The best time to use WhiteCap™ is early in the spring a couple of weeks before you normally see duckweed forming in your pond. This will give the herbicide a chance to establish itself in the pond and discourage plant growth before it gets out of control.

I’ve always been told to use lava rock in my waterfall filter, is this the best media to use? | Decorative Ponds & Watergardens Q&A

I’ve always been told to use lava rock in my waterfall filter, is this the best media to use?

I’ve always been told to use lava rock in my waterfall filter, is this the best media to use?
Tara – Bon Temps, LA

Lava rock was a common form of biological filtration media in waterfall boxes as its porous surface provides room for bacteria to reside. While it was popular years ago, pond supply companies have since produced better forms of secondary biological filtration media that are friendlier for both you and the pond itself.

Using lava rock as a source of filtration media has a list of distinctive drawbacks. The first of which is that it can prove to be extremely heavy and cumbersome. It is not exactly easy to lift a bag of rocks out of your pond, especially when it is full of water and debris.
While lava rock is porous and can initially provide a reasonable amount of additional surface area, the coarseness and small opening sizes tend to hold on to passing-by debris, blocking the waterways which greatly diminishes the stone’s performance. Once lava rock is loaded with debris you will have to remove it form your filter box and replace it with new media as it is near impossible to remove the debris from within each rock. For some pond owners this means they would need to replace their lava rock media multiple times each season for optimal performance. Furthermore lava rock tends to be brittle and can leave behind additional dust and debris in your pond.

Biological filtration media like Pond Logic® BioBalls™ filter media provides all of the surface area that your beneficial bacteria desire but implement it into a light-weight cost-effective design. One of the best qualities of secondary filtration media like the BioBalls™ is that you only have to buy them once. Pond Logic® BioBalls™ do not degrade over time and can simply be rinsed out at the end of the season and reused the next. BioBalls™ can placed into a mesh media bag and can be placed right into your waterfall filter box.

Pond Talk: Have you used lava rock as filter media in the past and switched to bio balls or another form of media? Did you notice a difference in filtration performance?

What’s the best way to introduce new fish to my pond?
Chelsea – Eagan, MN

So you’ve made the decision to invite a few new friends to your home, but are you getting more than you bargained for? As is true with any purchase, you want to make sure you are getting quality before you hand over your hard-earned dollars. Inspect the fish you intend to purchase for symptoms of illness or poor health. Look over their fins, mouth, and gills for blemishes, discoloration, or signs of fin rot and check their body for growths, loose or missing scales, or other blemishes as they may be an early indicator of disease or parasites. Take a few moments to observe your prospect’s behavior to make sure they are active and having no mobility hindrances.

Your newly purchased fish are typically handed over to you in an oxygenated plastic bag or container to allow adequate time to transport them to their new home. While it may be tempting to just dump them into your water garden upon your return home, you will want to make sure your pond is ready to accommodate its new inhabitants before you begin their acclimation process. Here are a few things to keep in mind:

Make sure the water in your pond is free from potential fatal heavy metals and chlorine and replenish the protective slime coating of your fish by adding Pond Logic Stress Reducer Plus during your water changes.

To help prevent disease and reduce fish stress in your new tenants, add Pond Salt to the water between your water changes. To ensure the well being of your Aquatic Plants, only add 1 1/4 cups per 100 gallons of pond water.

You can purchase a Master Test Kit to verify acceptable pH and Nitrate levels in the pond.

You can prevent many potential health issues throughout your fish population by simply maintaining a clean and healthy pond. You can read more about pond maintenance here.

Now that the pond is ready for the addition of fish, it is time to get your finned friends ready for the big show. You will want to gradually equalize the temperature of the water your fish are currently occupying with that of the water in your pond. If the container carrying your fish floats, go ahead and place it in your pond. As the bag bobbles around in your pond, the water inside will start balancing with the outside water temperature. This process should take no longer than 30 minutes.

During this time frame, slowly add small amounts of water from the pond into the container which will allow your new fish time to acclimate to the chemistry of your pond water. Most of us have, at one time or another, jumped into a pool too early in the summer only to find that the water is unimaginably cold. Those of you who’ve been in that situation understand why you will want to take your time with the acclimation process. Now that the water on both sides of the container is the same and the fish have had time to try out the make up of the water in the pond, you are clear to release them into their new environment! Take a few moments throughout the day to check in on the pond and monitor the behavior of the newly introduced fish. Active and curious fish are happy and healthy fish.

How can I reduce algae growth in my pond? | Pond & Lakes Q&A

How can I reduce algae growth in my pond?

How can I reduce algae growth in my pond?
Ryan – Dallas, TX

As we progress through spring and into summer, it is important that you know how to treat algae growth should you experience an algae bloom. Persistent algae blooms will still flex their muscles even if you maintain a clean pond. There are really two approaches, a reactive approach-treating growth, and a proactive approach-treating the source.

Reactive Approach-Treating the Growth
You can provide a temporary relief from algae by treating these algae break-outs with an algaecide like Pond Logic Algae Defense or Cutrine Plus Granular. It is best to treat the algae first, making contact between the chemical and the target algae as much as possible and then raking out the debris once dead. If the algae mat is more then an inch or two thick, you may want to rake out some of the algae before treating. To apply use a Tank Sprayer or Hand Spreader to kill off the remaining algae particulate. Once the treated algae dies and browns out, remove the debris with an Airmax Lake Rake so it does not sink the bottom of the pond and decay, encouraging new growth.

When selecting the type algaecide to use you will want to observe any use restrictions the product may carry. Algae Defense and Cutrine Plus granular are a popular choice as they do not carry any water use restrictions. . These products do however contain chelated copper which will not harm the pond or most common gamefish but are not as friendly to koi, goldfish or trout if carbonate hardness is less than 50ppm. You can test your carbonate hardness before treatment with a carbonate hardness test kit. If these types of fish inhabit your pond and you are looking for another option you may want to consider using Hydrothol 191. This product does carry some water use restrictions however it does not contain copper.

Proactive Approach-Treating the Source
Proactively treating your pond before you actually experience algae blooms can save you time and money in the long run. Algae blooms tend to be a symptom of a much larger problem – a dirty pond. By using only algaecides for pond maintenance you allow your pond to continue to accumulate organic debris and fuel for bigger and more stubborn outbreaks.
If your water temperatures are already around 50 degrees or above you can enlist the help of beneficial bacteria and natural water treatments to reduce organic debris and bind phosphates. Pond Logic PondClear can be used to treat your entire water column and attack floating suspended organics that cause turbid water. Pond Logic MuckAway sinks to the bottom of your pond to eliminate pond muck. Pond Logic EcoBoost naturally binds the phosphates helps sink floating particulates to increase water clarity. EcoBoost also introduces trace minerals into your pond which improves the health of your game fish. Remember to also run your Airmax Aeration System. Aerating your pond will ensure a healthy and well balanced pond for your fish during times of added stress while treating for algae, as well as to promote beneficial bacteria like PondClear to continue to breakdown any debris you may have missed while raking.

Brad – Phoenix, AZ

Pond owners looking to flex their green thumbs this spring are already planning their aquatic plant purchases. Including plants in your water garden or decorative water feature can help add shade and filtration to the water body while painting the landscape with beautiful colors and accents.

The Ann Chowning Iris is an excellent selection for ponds that are exposed to constant sunlight. The Ann Chowning has intense red flowers with deep yellow accents. The flowers have a velvety texture and the iris produces beautiful evergreen foliage growing to a height of 36” and a width of 18-24”. Blooming in the spring and into summer, the Ann Chowning iris prefers full sun but will tolerate some late hour shade. The brilliant contrasting colors make this iris a great cut flower that can be used in centerpieces and indoor decoration. For pond owners in more remote locations the Ann Chowning is a great choice as it is resistant to deer which love to frequent ponds for a quick snack and drink.

As with other aquatic plants the Ann Chowning can be planted in media baskets with planting media and placed in and around your pond or water feature. As the Ann Chowning prefers moist, well drained soil you will want to keep this iris contained to the shallow regions and edges of your pond. Be sure to fertilize your plants with pond-safe plant fertilizer to achieve even brighter and bolder colors.

Jan – Raleigh, NC

Pond owners looking to replenish their fish populations this season should grab their buckets and nets; spring is here and it is the perfect time to stock your pond with new game fish.

Spring and fall are the best times to add new fish to your pond as the temperatures are not as harsh making it easier for you to transport your newcomers and acclimate them to their new home. You can still introduce fish into your pond during the summer months but you will want to take extra precautions to make sure you can quickly transport the fish to your pond and take a little extra time during the acclimation process.

Deciding how many fish to add to your pond will predominately depend on the surface area of the water body. You can take a look at a few examples of stocking rates on our website. You will want to stick to a ratio of 3 prey fish (sunfish, bluegill, or perch) to 1 predator fish (bass) when choosing species to promote a healthy and balance fish population. Click over to our Fish Stocking Blog for some more information.

You can purchase fish from your local fish hatchery or catch and transport fish from a friend’s pond. Wherever the source, inspect the fish for signs of illness or disease before adding them to your pond. Our local customers can take advantage of The Pond Guy semi-annual Fish Day which takes place on the 7th of May. Fish day is a great opportunity to meet with other pond owners, speak with the friendly and knowledgeable The Pond Guy staff, and browse our wide selection of pond products from Pond Dye to 10’ Windmills. Customers can place orders online or over the phone until May 7th which will be available for payment and pick-up on the 8th between 11 a.m. and 1 p.m. There will be a wide selection of both predator and prey fish available for purchase including Hybrid Bluegill, Perch, Catfish and Bass. Walk-ins are welcome but selection will be limited by availability.

Make sure there is adequate habitat for your smaller fish to hide, grow and reproduce. Weeds, grasses and other debris already in your pond will provide some cover but you can introduce man made habitats to protect your fish without dealing with weeds and plants. Check out our Fish Habitat blog for some more insight into creating comfortable living spaces for your fish.

What do I do to clean out my water garden now that the snow melted? | Decorative Ponds & Water Gardens Q&A

What do I do to clean out my water garden now that the snow melted?

What do I do to clean out my water garden now that the snow melted?
Brett – Delta, IA

Spring is the perfect time to perform a clean out on your water garden or decorative water feature and remove accumulated growth and debris from the winter months. Not only does this result in a cleaner better looking pond, it also promotes a smoother transition into the warm summer months where a unbalanced pond can easily be overrun with green water and string algae.

Once the ice melts from the surface of your pond you can begin your cleaning regimen. Start by pulling out as much muck and debris as possible. You can use a Interchangeable Pond Tool to safely remove your decorative pond fish and sweep debris away from the sides of the pond. Pond Vacuums are a great way to siphon muck and debris from hard to reach areas of your pond without the hassle of bending and scrubbing. Sprinkle Oxy-Lift Defense™ on your waterfall rocks and stream bed to lift stuck on debris without having to scrape at your rocks and liner.

After the majority of debris are cleaned from the pond you can perform a partial water change by removing around 20% of the ponds volume and replacing it with fresh water. Not only does this refresh the pond water, removing water from the pond with a pump or bucket will also eliminate some of the floating debris you kicked up during the cleaning process. While the pond is refilling mix in some Water Conditioner to remove the harmful metals and chloramines found in well and tap water.

Remove your Filter Media Pads from your waterfall filter, skimmer and pressurized filters. Inspect them for signs of wear and tear and replace accordingly. Thoroughly rinse your filtration media to remove built up debris. Apply PL-Gel to your new or cleaned filter media to seed them with beneficial bacteria and place them back into position.

Now that the pond is cleaned up and topped off you can start up your pumps and begin circulating the contents of the pond. Inspect the pumps, plumbing and power cords for signs of wear, cuts or leakage. Check your waterfall and streams for out of place rocks, splash-outs, and misdirected water. Black Waterfall Foam can be used to keep rocks firmly in place and route water where you want it. Inspect your pond liner for leaks and check the perimeter of your pond for damp areas or puddles.

If the water is still below 55 degrees apply your Pond Logic® Seasonal Defense® to balance the pond water and introduce beneficial bacteria to the water column. If the water warmer than 55 degrees you can apply your Nature’s Defense® instead. The Pond Logic® DefensePAC® bundles the water treatment and maintenance products you will need for the season while providing a price break compared to purchasing products individually.

Let the pond water circulate for a couple days before re-introducing your decorative pond fish back into the pond. This will give the pond water some time to balance without putting unnecessary stress on your fish. Add some Stress Reducer Plus to the water before you start acclimating your decorative pond fish back into the pond as it will help supplement their slime coat and reduce exposure to stress and harmful residual water contaminates.

While it requires a little elbow grease up front, a thorough spring clean out will save you time, money and hassles later in the season so you can spend more time enjoying your pond while the weather is nice.

Help! There are a bunch of dead fish in my pond, what happened? | Pond & Lakes Q&A

Why do frogs/toads make so much noise?

Help! There are a bunch of dead fish in my pond, what happened?
Jason – Hastings, NE

The arrival of spring is an exciting time for pond owners. The weather is warming up, the sun is shining and the ice is melting away from the surface of your pond. Some pond owners however, find all of their fish floating dead at the water’s surface. While experiencing a winter fish kill is not the best way to start the season if you understand the cause you can prevent future occurrences.

Your pond is constantly absorbing and releasing air. As wind blows across the surface of the pond water ripples absorb oxygen into the water column. Decomposing organic debris at the bottom of the pond release a gas that floats to the surface of the pond where it is released into the atmosphere.

The layer of ice that forms over your pond blocks air exchange locking fresh oxygen out of the pond and harmful gas from decomposition in. Depending on the size of the pond and the amount of decomposing debris available, your fish can be overwhelmed and killed by the lack of fresh air.

Fish kills can also happen in the summer. Summer fish kills are typically caused by pond turnovers due to lack of proper aeration. The top layer of water in your pond carries more oxygen and reacts faster to temperature changes due to its exposure to the air. The bottom of your pond will tend to contain less oxygen, light and will be slower to warm up throughout the summer. These layers of water are referred to as stratification and are divided by thermoclines. If you have ever swam in your pond you may have noticed that your feet are colder than your chest as they break the thermocline in the water column. Your fish will find a happy medium in the water column where there is adequate oxygen and warmth.

Particular rainy or windy days can cause the thermocline in your pond to break. The bottom layer of water in your pond will mix together with the healthier top layer of water. As your fish have nowhere to flee to, they are trapped in the newly mixed pond water which can severely stress and even kill your fish.
Fortunately, there are a couple of ways to prevent winter and summer fish kills. An Bottom Diffused Aeration System like the Airmax® AM Series pumps fresh air to the bottom of your pond and breaks it into fine bubbles that can be absorbed into the water column. As the air bubbles rise through the water column they also circulate the water body making sure that your pond is evenly oxygenated and warmed. An abundance of oxygen promotes the presence of beneficial aerobic bacteria which will help break down organic waste faster and without the egg-like odor produced by the slow anaerobic bacteria in water that lacks oxygen. Running an aeration system in the winter can also eliminate your winter fish kills as the constant bubbling at the surface of your pond prevents ice formation and quickly breaks up layers of ice.

To further aid in your fish kill prevention, you will want to remove as much organic debris from the bottom of the pond as possible. Beneficial Bacteria products like PondClear™and MuckAway™ in tandem with EcoBoost™ will naturally digest gas and algae causing muck without having to chemically treat your pond. Cut down and drag away any dead cattail reeds and leaves with a Weed Cutter and Rake so that they are not left to decompose. The Pond Logic ClearPAC® Plus combines all the beneficial bacteria products you need along with pond dye and an option algaecide to eliminate the guesswork of selecting the proper pond care products.

Why do frogs/toads make so much noise? | Pond & Lakes Q&A

Why do frogs/toads make so much noise?

Why do frogs/toads make so much noise?
Stephanie – Pasadena, TX

With the official start of spring come and gone we are not the only ones excited about the rising temperatures. You will soon be serenaded by the assembly of frogs and toads that set up camp at your pond and lake. These frogs and toads can get quite boisterous as they let out calls that can be heard from miles away.

It is not the warm weather or a particularly good day that makes frogs and toads sing however. When toads and frogs call out they are actually trying to attract a mate. Both frogs and toads are capable of croaking but calls vary between each species allowing their mates to distinguish who’s who amongst the gathering of suitors. It is the male who calls out to potential female mates in an attempt to present itself as the best possible option as it is competing against a long line of bachelors. The size and health of each particular frog or toad, along with temperature can dictate the strength, pitch and carry of its call.

While most people enjoy the ambience provided by these calls, the impressive noise a chorus of frogs can produce can become problematic. If you find the noise troublesome you can try to encourage frogs and toads to move elsewhere by discouraging their habitat. Using tools like a Pond Rake and Weed Cutter you can cut and pull away plant debris and growth from around the shoreline of the pond. Without the protection from predators these frogs and toads will not be as inclined to call your pond home.

Pondless or pond? Why not have both!

Pondless or pond? Why not have both!
Alvin – Boulder, CO

One of the greatest elements of decorative ponds and water features is that each can be as unique and distinguished as the person creating it. The shape, style and implementation of your water garden is limited only by your imagination. It is this freedom to inspire and create that keeps pond owners incessantly engaged in the hobby.

In previous blogs we have discussed the different types of ponds and water features available along with some of the perks and drawbacks of each type. While any of these water features, waterfalls, and ponds are great on their own, you can also incorporate the different feature types to create a truly breathtaking water feature.

A great example of combining feature types into one functional display is the combination of an elevated pond that cascades down into a pondless waterfall. Think of this feature as a pondless water fall type water feature with a pond half way through the waterfall. Combining these two features opens up possibilities that may have been impractical with a certain feature alone. Pond owners with children are often drawn to pondless features as there is no potentially hazardous standing water body for them to wander into. By elevating the pond to a height that is out of reach you can still enjoy the freedom to incorporate fish and plants into your water feature while the pondless waterfall safely returns water underground and out of reach. As you will have to purchase the major components for either a pond or water fall feature, adding the additional parts to incorporate the two features together is easier and more cost effective than having to buy items for two separate features. Both Pond Kits and Pondless Waterfall Kits are available for purchase to eliminate the guesswork of what items your need to construct either particular feature. To simplify the purchasing process you can purchase a Pondless Waterfall for the main components and some additional 45Mil Rubber EPDM Liner and Seam Tape to construct the elevated pond.

Laying out and combining advanced water features and ponds may require expert advice or guidance. You can Chat Live, eMail, or call and pond guy or gal to help you choose the products that will need for your water feature. When constructing any type of pond or water feature it is imperative that you take your time and plan accordingly to ensure a smooth and enjoyable pond building process.
