How to Get Rid of Algae in a Pond - The Pond Guy

There is nothing worse than watching your pond turn green or seeing buildup on your waterfall rocks. For those seeking to learn how to get rid of algae in their pond, there are a variety of products, both chemical and chemical-free, that can help.

Why do ponds need pesticides?

Pesticides in ponds may result from their use on nearby land areas or from aquatic herbicides used to reduce plant and algae growth. When using aquatic herbicides, make sure you obtain the required state permit, and read and follow the herbicide label instructions carefully. In some cases, the pond water should not be used for swimming, irrigation, livestock watering, or fish consumption for a specified period of time. Many aquatic herbicides are also toxic to fish and should be used carefully in ponds with fish.

How to change the temperature of a pond?

Little can be done to alter the temperature of pond water. Groundwater may be pumped into the pond to create cold-water ponds during the summer. In most cases, however, it is best to match the types of fish stocked in a pond with the existing temperature regime. Cold-water fish prefer maximum water temperatures below 70°F, while warm-water fish like bass and bluegill prefer summer temperatures in the 80s. Water temperature is also important when using aquatic herbicides to treat plant or algae growth. Aquatic herbicides are most effective when water temperatures are between 60 and 75°F. Consult the herbicide label for details.

What causes muddy water in a pond?

It is frequently caused by runoff from disturbed areas around the pond or from bottom-dwelling fish and muskrats. Muddy water is best solved by eliminating the source of the problem. This might include planting grass or other vegetation on exposed areas, putting a layer of rocks over exposed banks, or removing muskrats or bottom-dwelling fish. Persistent muddy water problems can be treated with additions of ground limestone, hydrated lime, gypsum, or alum. Ponds that are only turbid or colored during the summer are probably experiencing zooplankton blooms. Zooplankton are small animals that serve as a food source for fish and other aquatic life. Zooplankton can be distinguished from sediment in water by holding a clear glass of pond water up to a bright light. If most of the particles in the water move erratically, the pond is experiencing a zooplankton bloom. If the particles do not move, sediment is the cause of the water discoloration. Zooplankton blooms can be eliminated with copper sulfate, but in most cases the health of the pond is best served if they are left untreated.

Why is it important to keep a pond warm?

Ponds that are generously fed from underground springs will have colder water that can support cold-water fish such as trout. Temperature can vary greatly throughout the pond, with surface water affected more by air temperature than deeper water. Thus, the top of the pond will be slightly warmer in the summer and colder in the winter than deeper portions of the pond.

How can zooplankton be distinguished from sediment?

Zooplankton can be distinguished from sediment in water by holding a clear glass of pond water up to a bright light. If most of the particles in the water move erratically, the pond is experiencing a zooplankton bloom. If the particles do not move, sediment is the cause of the water discoloration.

Why do you test pond water?

Test the pond water periodically to determine bacteria levels and to monitor the presence of any other non-visible problems.

What are the concerns about pond water quality?

Concerns about pond water quality are directly related to the use (s) of the pond. As with all pond management decisions, consider the primary uses of your pond to determine which water quality parameters are of greatest concern. For example, a pond used to supply drinking water for animals should be tested for different parameters than a pond used exclusively for fishing. Table 1 summarizes the important water quality parameters and pond uses that are described in this fact sheet.

What fish like warm water?

Bass, bluegill, and catfish prefer warm-water ponds (warming to more than 75° F). Cool-water ponds (in the 65° F - 75° F range) may, depending on the size of the pond, support smallmouth bass or walleye. Some ponds in this temperature range may also support cold and warm water fish.

What temperature should a pond be for trout?

Temperature: The temperature determines which species of fish will thrive in your pond. Cold-water ponds (remaining under 70° F) are preferred by trout.

What is the oxygen level of a fish pond?

This is the oxygen that fish need to survive. An adequate level of D.O. for most fish is 4 ppm ; salmon and trout, however, require more than 6 ppm.

What pH should a pond be?

This can be accomplished with an initial fertilization and continuous input of fish feed. pH: This is the level of acidity of the water. Most fish prefer a pH of 7 (neutral).

How deep should a pond be for weed control?

The minimum pond depth for underwater weed control is 3 feet; information on minimum depth to prevent winterkill in your area is available from local extension agents.

What are the factors that determine the quality of a pond?

4. Pond water quality. There are five main factors that determine the overall quality of water in a given pond. These include: Fertility: This is the amount of nutrients in the water available for the growth of microscopic plants called phytoplankton which are the first link in the pond’s food chain.

How to keep a pond full?

It should be adjacent to a source of clean, clear water. Soil in this area should be at least 30% clay so it will hold water. The watershed should be large enough to keep the pond full – typically 10-30 times the size of the pond. If the watershed is too large, or too close to fertilized cropland or livestock pastures, consider building a ditch around part of the pond to divert some of the water.

What Else Lives There Besides Microbes?

There are many other organisms besides bacteria that share the pond water. Many are every day organisms that we would find anywhere. Plants such as water lilies, duckweed, grass, and cattail are may be found present in water. There are mollusks, which includes clams, snails, and freshwater mussels. There are also insects such as dragonflies, damselflies, and water scorpions. Worms may also be found in ponds such as flatworms, leeches, and roundworms. It’s not surprising to find many amphibians, reptiles, and fish swimming in the water such as turtles, frogs, toads, salamanders, snakes, sunfish, minnows, bass, and carp in ponds. Finally, many birds and mammals travel around ponds and making contact with the water for feeding and/or shelter purposes. They include herons, mallard ducks, muskrats, and beavers.

Do the Microbes Carry Out Any Metabolism That Affects Their Environment?

All of Earth's living organisms need nitrogen to survive. About 78% of the Earth's atmosphere is nitrogen gas. Nitrogen in this state is unusable to all but a small number of organisms. Nitrogen fixing bacteria and blue green algae that live in ponds and soil are responsible for changing nitrogen gas in to ammonia, which is compound plants are able to use. Some plants (legumes and ferns with anabaena) have formed a symbiotic relationship with these organisms. Next, nitrifying bacteria further change ammonia from nitrogen fixing bacteria and decaying organic matter in to nitrites and nitrates, which are also taken up by plants and then animals. Nitrogen is returned to the atmosphere as gas from nitrates by denitrifying bacteria.

What is the most important element in life?

Sulfur is another important element to life. It is a major component in proteins and vitamins in plants and animals. Sulfur deposits are found in the sediment of lakes and ponds from decomposing organisms and tied up rocks, salts, and metals. Sulfate reducers at the bottom of the pond break down these sources of sulfur so other organisms can use them again. Sulfide on the bottom of ponds and in surface water is turned oxidized by bacteria in to sulfate which then can be used by other animals and returned to the biomass circulation.

How does pond water affect E. coli?

The environment surrounding a pond has many affects towards it. Factors such as sunlight, changing of seasons, and snowmelt play a huge role in a pond in which they are all able to affect a pond’s ability to decrease E.Coli count. For example, sunlight decreases E.Coli count by its UV radiation. The UV radiation can cause degradation some of the bacteria that are floating towards the surface of the water. Another example is snowmelt, which also decreases E.Coli count when it dissolves into the pond water.

How many bacterial isolates were collected from tilapia pond water?

It turned out that 75 healthy fish and 15 pond water samples commercial tilapia fish farms in the country were processed. After recovering 202 bacterial isolates from fish slurry and 88 from the water, it was concluded, “The predominant bacteria from fish slurry were Pseudomonas spp. (60.0%), Aeromonas spp. (44.0%), Plesiomonas (41.3%) and Chromobacterium (36.0%) (P < 0.05; χ2) compared with isolates from pond water where Bacillus spp. (80.0%), Staphylococcus spp., Alcaligenes spp. and Aeromonas spp. (60.0%) were most prevalent” (Pages 206 – 213).

Why is pond water murky?

Composition of water may be murky if it has a high amount of suspended particles and/or organisms. The bottom of a pond is usually sediment of sand, decaying matter and microorganisms. Pond water is usually stagnant. Nutrients are brought to the pond by the streams that feed into it, run off during rain, or by the snowmelt off ...

What are the insects that live in ponds?

There are also insects such as dragonflies, damselflies, and water scorpions. Worms may also be found in ponds such as flatworms, leeches, and roundworms.

Why is it good to have sunshine in a pond?

Good Morning, Sunshine. Ponds that have some sunlight are also beneficial to fish due to the valuable vitamins that are produced. Sunlight also helps the plants in your pond grow, thereby reducing nitrates in the water.

How many fish per 10 gallons of water?

Some pond experts go so far as to recommend only ½ inch of fish per 10 gallons of water as a maximum stocking density. On occasion, you may encounter ponds crowded with two or even three inches of fish per 10 gallons of water and the fish seem to be fine.

How much water do you need to grow fish in a pond?

It all starts with the size of your pond. You need to make sure that it is large enough to support fish and their growth. Pond fish generally need 10 gallons of water for every inch of their length, and you have to be ready for them to grow larger, so be careful not to overstock, no matter how tempting this may be! Some pond experts go so far as to recommend only ½ inch of fish per 10 gallons of water as a maximum stocking density.

What is the balance act in ponds?

A Balancing Act. The quality of your water is critical to pond fish health and you want to make sure your water garden is balanced. The proper mix of fish, plants, filtration, circulation, and rocks and gravel all provide an important role in your pond’s ecosystem.

What plants can tolerate shade?

Pond plants that tolerate shade include Taro, Papyrus, Horsetail, Cardinal Flower, Lizard’s Tail, and Water Forget-Me-Not.

Can you salvage sick fish in a pond?

You won’t be able to salvage sick fish in a pond that’s overcrowded. Eventually, Mother Nature will pick off your favorite fish to achieve her ideal stocking density based on the system the fish are in, and then the remainder will recover as if by magical intervention.

Can you move a pond?

Unfortunately, you can’t just up and move your pond so if you have a shaded pond, simply add shade-loving plants to help balance the water. Aquatic plants play a critical role when it comes to enhancing pond fish health.

What is the most important component of alkalinity?

Carbonates and bicarbonates are the most common and important components of alkalinity. A total alkalinity of at least 20 ppm is necessary for good pond productivity. Water with high alkalinity and similar hardness levels has a neutral or slightly basic pH and does not fluctuate widely.

What are the factors that affect pond water quality?

However, several other variables influence water quality for fish including water temperature, phytoplankton, photosynthesis and pH, carbon dioxide, alkalinity and hardness. Additionally, water quality can be affected through the interaction of these factors.

What is the function of alkalinity in pond water?

Alkalinity is water's ability to resist changes in pH and is a measure of the total concentration of bases in pond water including carbonates, bicarbonates, hydroxides, phosphates and borates. These bases react with and neutralize acids, buffering changes in pH. Carbonates and bicarbonates are the most common and important components of alkalinity.

Why do phytoplankton die?

Extended periods of cloudy weather can cause a phytoplankton die-off, using oxygen during decomposition. If phytoplankton are too abundant in a pond, the amount of oxygen used during nighttime respiration can cause oxygen depletions for fish. Oxygen levels are usually lowest during the hour just before daylight.

Why does the pH of pond water fluctuate?

Pond water pH fluctuates throughout the day due to photosynthesis and respiration by plants and vertebrates . Typically, pH is highest at dusk and lowest at dawn. This is because nighttime respiration increases carbon dioxide concentrations that interact with water producing carbonic acid and lowering pH.

What is the result of a sudden dilution of oxygen and a simultaneously increased demand for oxygen from decay?

This is often referred to as "turn-over.". The result is a sudden dilution of oxygen and a simultaneously increased demand for oxygen from decaying organic matter. This can cause severe fish kills. Phytoplankton are microscopic plants that produce most of the oxygen and are the base of primary productivity in a pond.

What is the alkalinity of a freshwater pond?

Alkalinity should be at least 20 ppm. Optimum range of alkalinity for most aquatic species in freshwater ponds is between 50 and 150 ppm.

What is the purpose of habitat analysis?

The purpose of Habitat Analysis is to verify there is sufficient habitat in and around the pond for fish utilization and erosion control. This step simply requires a look at the pond and its immediate surroundings.

Why is calcium hardness important?

Total Hardness is important because calcium is critical in the formation of bone structures as fish grow. Total Hardness of 100 - 250 mg/L CaCO3 is optimal. If your test reveals numbers outside of these ranges, don't worry because these issues can often be resolved by treating with gypsum or limestone.

How does electrofishing work?

From the data collected during the survey, we can ensure your populations are balanced between predators and forage at the necessary ratios , ensure age and size classes are balanced within a species population and check on your fish's growth rates by comparing age to their length and weight. This data guides us as we harvest or stock necessary species to balance the populations and communities within the ecosystem. By maintaining a well-balanced fish population, growth rates, and recruitment rates of all species improve, leading to greater sustainability and better fishing down the road.

How to take water samples?

When taking water samples, do not take water directly off the surface. Instead, turn the water bottle upside down, so the trapped air prevents water from entering the bottle. Push the bottle down about 6 inches beneath the surface, then turn the bottle on its side, allowing the air to escape, and water to fill the bottle. One full water bottle is sufficient for most testing purposes.

What is the nursery habitat for fry?

Nursery habitat for fry and juvenile fish is critical for recruitment to ensure sustainable populations of fish. This can be grasses, bushes, or reeds in or near protected shallow pockets that give the small fish a place to evade predation, reducing their mortality rates.

What is the best pH level for fish?

The 3 main things we look for in our water quality test are pH, Alkalinity, and Total Hardness. Optimal pH levels are 6.5 - 9 ; however, fish can still survive well outside this range. Alkalinity is the water's ability to buffer pH swings and is measured in mg/L CaCO3.

Is a pond healthy?

Customers often ask, "Is my pond healthy?" or "How do I know if my pond is healthy?" and the honest answer is there is no such thing as a "healthy" or "unhealthy" pond. Each pond has its own specific ecosystem, and these ecosystems often vary depending on several factors such as ecoregion, available habitat, watershed size, or substrate composition, just to name a few. It is because of these variances that there is no clear definition for a "healthy" pond. Perhaps a better question would be, "what is the condition of my pond ecosystem?" or "is my pond ecosystem conducive to fish production/growth?" These questions can be answered by water quality testing, habitat analysis, and electrofishing surveys.

What is the third tip of a pond?

The third tip and perhaps the most important to the overall long-term health of your pond is to prevent and control sources of sediment and nutrients from entering the pond . Nutrients and sediment control start with understanding the pond watershed or the land area that contributes water to the pond.

Why do you fertilize a pond?

If you mow grass clippings into the pond, like in this picture, you are in effect fertilizing the pond because the grass will decay and release nutrients into the water. Aeration is another method to reduce the availability of nutrients in the pond.

How to control nutrients in pond?

Perhaps the easiest method to control nutrients entering the pond is to establish a riparian buffer strip of unmowed grass and shrubs around your pond. Even a simple buffer strip of grass that is only mowed a few times each summer is beneficial.

How do buffer strips work?

Buffer strips can capture nutrients before they enter the water, control erosion, and remove sediment from the water by slowing water velocity. Limiting fertilizer use on the land area around the pond is very important to prevent nutrients from entering the pond, where it can grow plants and algae.

What causes fish to die?

These include excessive algae and plant growth, nuisance wildlife, or water quality problems that lead to fish kills.

What are the problems with earthen ponds?

Many earthen ponds have problems with algae, nuisance wildlife, or water quality. This video provides a few simple tips to help solve or prevent these common problems and ensure a healthy pond.

What are the parameters that must be measured at a pond site?
