Whether you want a gin-clear swimming pond or a monster bass honey hole, phosphorus plays an important role in your pond. In a clear pond with low productivity (oligotrophic), phosphorus levels would typically be under 10 parts per billion (ppb). A pond with high productivity (eutrophic) will likely have about 96 ppb (Lory).
What happens when phosphorus levels are too high in a pond?
The effects of this buildup can become unhealthy to the water, fish, and aquatic organisms. If your pond has nutrient buildup, we recommend reducing phosphorus levels early on to improve the health of the water. Here’s what happens when phosphate levels are too high.
What should the pH level be in a fish pond?
That being, what should your pH should be and how to change your pH level. A fish’s natural pH level is 7.4. So, it’s best practice to keep your pond as close to this level as possible. Fish can tolerate slight fluctuations in the acidity or alkalinity of the water.
How do you use phosphate in a pond?
Phosphate can be presented into pond water by many forms. One of them may be soil in planting containers before aquatic plants are planted into the pond, as there are fertilisers in the soil prior to planting to help them grow. Another reason may be tap water that is used to fill up the pond.
What are phosphates and how do they affect water quality?
The saying “everything in moderation” can apply to many situations—even organic nutrients in water. Phosphates are a form of phosphorus that naturally occur in ponds and water features. Depending on the surrounding environmental factors, like rainfall, fertilizer runoff, and more, the levels of this nutrient can vary.

Why do ponds have phosphate?
Phosphate Levels. Phosphate can be presented into pond water by many forms. One of them may be soil in planting containers before aquatic plants are planted into the pond, as there are fertilisers in the soil prior to planting to help them grow. Another reason may be tap water that is used to fill up the pond.
How does ammonia affect fish?
Ammonia is released into your pond when your fish excrete waste. The nitrifying bacteria that are fed by calcium carbonate then break down the ammonia and turn it into Nitrite. Nitrite is then broken down further, to its final state, Nitrate. Nitrate is the final by-product of Ammonia. All three of these can be dangerous to your fish and should be monitored carefully. Ideally, you should be removing any Ammonia in your pond to avoid it damaging your fish or breaking down further. Ammonia can cause Ammonia poisoning that can lead to death. Nitrites and Nitrates are not as dangerous. However, if your fish already have Ammonia poisoning they will be weak and susceptible to the irreversible effects of Nitrates.
What is KH in pond?
KH is the measure of carbonate hardness in your pond. Carbonate hardness is the amount of calcium carbonate in your pond. Calcium carbonates are very important. They feed the nitrifying bacteria that remove harmful ammonia and nitrates from your pond water. These bacteria are part of your ponds bio-filter.

How much oxygen can a fish hold in a pond?
The maximum amount of dissolved oxygen that can physically be held in water is 18.0mg/L. The minimum that you should let that figure get to is 6.0mg/L. Anything lower than this and your fish will start to suffer. Some fish will be able to tolerate lower oxygen levels than this. However, it is advisable to try and keep the minimum at 6.0mg/L. Cold water can hold almost twice as much oxygen than warm water. So keep a close eye on your pond oxygen levels throughout the summer months.

Why is phosphorus so difficult to manage?
The majority of phosphorus pollution in rural areas come from non-point sources such as cropland erosion and runoff, which is why nutrient pollution can be so difficult to manage. In freshwater untouched by nutrient pollution, plant and algae growth is slow and limited due to the low levels of phosphorus that occur naturally.
How can management help reduce phosphorus pollution?
Management practices can help reduce phosphorus pollution. Each case of nutrient pollution is unique , as different point or non-point sources can be at fault. Therefore, practices are usually specific to the sources, and what works for one case may not be suitable for every farm operation. However, there are some guiding principles that can apply to many agricultural operations.
What happens when a pond is bottom up aerated?
Once the phosphorus and other polluting nutrients have been broken down, bottom up aeration infuses the water with oxygen, allowing the digested nutrients to make its way out of the pond and into the air.
What happens when phosphorus is released into the environment?
When excessive amounts of phosphorus are released into the natural environment it causes environmental issues such as reduced levels of oxygen, accelerated plant and weed growth, and algae blooms of blue and green algae. The poor quality of water will cause a number of problems whether the water is used for irrigation, livestock, or drinking, contaminated water can be costly and difficult to treat.
What is the pH of a pond?
pH. The pH of a pond or lake should generally fall between 6.0 and 9.0. Different types of fish tolerate different pH levels but, in general, most fish will do better in ponds with a pH near 7.0. Ponds with a pH less than 6.0 may result in stunted, reduced or even absent fish populations.
How to treat low pH ponds?
Low-pH ponds are often treated by applying limestone. This is most easily done by broadcasting pulverized limestone over the pond surface. Application rates of one to two tons of limestone per surface acre of pond are common but will vary depending on the pond pH and the rate of water moving through the pond.
What is hardness in ponds?
Hardness. Hardness is a measure of calcium and magnesium concentration in water and is controlled by the source of the pond water. Ponds in limestone areas will generally have harder water than those in areas underlain by sandstone or shale. The hardness of pond water is usually unimportant except when using some aquatic herbicides.
What is measurable alkalinity?

When you have a stubborn algae bloom that you can't seem to bring into line, then consider checking the phosphate levels in your pond. Even low levels can stimulate algae.
Can phosphates kill algae?
Phosphates Feed Algae - Stop Them With This! There are several nutrients that can affect algae growth in a pond, but none are more potent and stimulating than phosphates. Simply put, without phosphates, you would have no algae bloom, and the higher the phosphate levels, the more aggressive the algae will grow!
How to know if a pond has phosphate?
Most of the time, the presence of phosphate in ponds and aquariums is not noticed until nuisance plant-like creatures start to grow. In outdoor ponds specifically, you will know if phosphate compounds are present if the color of the water starts to become pea green. Since phosphate is used as a fertilizer for plants to grow fast, expect to see algae to develop in your phosphate-infested pond water. Cyanobacteria or most commonly known as blue - green algae have bigger chance of residing in your pond if the phosphate contamination is not controlled.
Why should we check phosphate levels in the water?
Phosphates trigger the growth of unwanted living creatures in the pond like algae and blanket weed. If the origin is dealt with first, it is much easier to deal with the by-products. The less phosphate compounds present in your pond, the easier the maintenance will be . The use of algaecides and other pond necessities will surely be lessened once the phosphate levels in the pond are controlled.
Can a water pond test help with headaches?
