Using Pond Water For Plants

Having a pond near your house is a blessing. Not only for the beautification but for other purposes as well.

But is it right to use pond water for plants? Yes, it is. Only if you contain all the essential nutrients needed to make the pond and its water healthy. You may ask what is pond water and what makes it healthy? First is the temperature, the suitable temperature is for aquatic pond life, the healthy the pond water is. Second is the liquified oxygen, which is, of course, the reason for aquatic life. Other factors are murky water, nutrients, and more.

Further in this article, we will briefly talk about pond water, its uses, what it is comprised of, and more.

Is Pond Water Good for Plants?

The pond water is said to be very good for plants of many kinds, if not all. But in order for that to be, there is something that must be done first. The population comes first. The fish in the pond should be small to keep the pond from becoming overpopulated.

Then, keep a check on your fish’s food consumption, be careful not to overfeed them, because when the fishes are full, they will leave the food in the pond to decompose there and this is not a good thing for the pond. Furthermore, consider providing them with food that can float on the surface of pond water, rather than lying in the bottom.

Try covering half of the pond area with plants during the springs and summers. Remember to keep the balance, as unnecessary plants will create certain complications in the pond water. The more the plants, the more oxygen they use during the night, leaving little to no, for the aquatic pond life.

Always keep the pond water pump clean. Be sure to clean it every 2 to 3 days to ensure that nothing is blocking or compromising the pond water quality in any way. Clean the pipelines before it is late. Finally, keep the pond water at less than 70 degrees Fahrenheit in temperature to keep the liquified oxygen intact. How do you keep it cool? By using plants to cover it from above.

Take care of these things and your pond water is all set to be used for various purposes. Answering the question, Yes! pond water that is well-taken care of is good for plants in your garden.

What Does Pond Water Contain?

Pond water, like all other kinds of water, is made of certain types of compounds, gases, sand, nitrates, and sediments. Tiny and larger stones can also be found in the pond water. These nutrients are obtained by fish wastes, dying plants, and other sources.

These nutrients are comprised of nitrates and some other plant nutrients. The nutrients that are mostly found in the pond are macronutrients, along with other micronutrients as well. The ponds which have relatively more fish tend to have more natural nutrients from those fish wastes.

However, these wastes have nitrites and other toxic compounds in them, which can be harmful to fish and for the pond also. To reduce the risk to aquatic life in the pond. Thankfully, the Nitrogen Cycle is here to save the day as it turns the nitrates into other chemicals, benefiting the pond.

Nitrates:

Is a higher quantity of nitrate present in pond water a problem? Yes, it is. Not only that it severely affects the aquatic life in the pond but it also causes algae to grow rapidly in the water, making it green, if the nitrates are not removed instantly.

Nitrates are created in ponds by the fishes themselves. So if you get rid of the fish, you get rid of nitrates. But you would never do that, right? You want a solution without throwing the fish out. Well, you have to keep a strict balance of their food. Don’t feed them more than they can take.

Other Plant Nutrients:

Other than nitrates, the water of the pond contains some rich nutrients that are beneficial for plants. Due to these rich nutrients, pond water becomes ideal for plant growth. Furthermore, this water is used to increase the quality of the soil. Not only for the smaller garden areas but even on some big fields as well.

For a very long time, pond water has been used for simple and irrigation use. This water can increase the growth rate of the plants by enriching the soil. Also known as “Natural Fertilizer”, the pond water positively affects the plants, if kept in balance.

The Dangers in Using Pond Water on Plants:

Despite the advantages of using pond water for plants, there are some drawbacks to it. The water contains some compounds that might not be good to interact with. Let’s discuss.

Ammonia:

Ammonia is created in the ponds by the breaking of waste, by fish and plants. The breaking of ammonia is usually carried out by the Nitrogen Cycle. But if the ammonia level is getting high, this is not a good thing for the pond life inside.

Nitrites:

When the bacteria break down the ammonia during the Nitrogen Cycle, the nitrites are created. Their presence in the water is a serious matter, as they can tie up the fish’s blood cells. Which causes several fatal diseases. If your fish is catching its breath at the surface, many times. That can be a sign of nitrites’ high quantity.

Low Oxygen Content Water from Algae:

The growth of algae on the surface of the water stops the sunlight from reaching the plants inside, making it hard to photosynthesize. That is why the algae must be removed at the early stages before any complications occur.

Grey Water:

Water that has been used already is called Greywater. Most people make ponds to accumulate greywater to filter and put it to good use. But that takes additional hard work.

Pathogens:

The water that has not been properly maintained and cleaned is where the pathogens find their ideal home. Pathogens are those living things that negatively affect the beings they come in contact with.

Can You Use Pond Water In Aquaponics or Hydroponics?

Aquaponic means that fishes and plants will grow simultaneously, and Hydroponics means that plants will grow without the need of using the soil.

Ponds that already have fishes in them are ideal for the aquaponics system, as the waste and decay of the fishes are consumed by plants for their growth purpose. Mostly the aquaponics uses the pond water, but nonetheless, the water can also be used in the hydroponics system, as the water is enriched with all the nutrients for plant growth.

Can you Use Pond Water on the Lawn?

Yes. In fact, by using the pond water, you won’t need to water the lawn daily, as the ponds sometimes have a self-sustained hydration cycle. Because of that, the plants and grass of your garden stay alive and fresh all the time.

It is a good idea to use pond water for lawns. Go for it!

Conclusion:

Overall, pond water has proved to be ideal in watering plants and using it for other purposes. The pond water is, in many ways, better than the normal water. Because of its minerals and nutrients. That is why its use is always beneficial with the right knowledge of it. Thanks.
