Pond Ecology

The interplay of the entity in the pond with the environment surrounding it is called Pond Ecology or Pond Ecosystem. Pond gardens are also considered an ecosystem.

Every pond ecology has its state, characteristics, and standards. However, the exaggerated amount of algae in a pond is the most chronic issue in fish ponds.

But, with the aid of nature and your help, controlling this uprising algae matter is possible. Supervising a pond’s ecosystem with consideration of nature leads to success.

Algae appear whenever there’s an unbalanced ecosystem. And whenever algae interfere with pond maintenance, the life of the fish and the plants will be in grave danger as this causes low oxygen levels.

Tips On How To Maintain A Clean Water Pond

Always make sure that your pond is free from any type and form of algae, as this can kill the fish and the plants by restricting them from having sufficient oxygen and nutrients needed to survive. Choose the safest brands of pool chemicals to avoid harming marine life.

Here are tips on how to maintain a clean water pond and a balanced pond ecosystem:

Choose The Correct Filtration System

Over filtering has never raised a concern as long as you have the stability of water condition. But it is best suggested that the filtration be parallel with the size of your water garden.

Cleaning your filtration system time to time can reduce lavish repair maintenance and will give the fish more safety.

Feeding The Fish

Feed the fish the right amount of food they can devour. Feeding them more than what they can eat in 60 seconds to 3 minutes is left to decompose in the pond. Always purchase fish foods that don’t sink to the bottom of the pond.

Natural food, supplementary food, and complete foods are the three types of food for the fish.

Fish Population

Sustain a healthy fish population. Otherwise, this can cause genetic drift when population size is too small for the pond or imbalance water pond when overpopulation occurs.

A suggested ratio for the fish population is 1:10, meaning one fish for every ten gallons of water.

Balancing The Plants In A Pond

Put plants that are beneficial for the fish. But do not place too many plants. It may result in oxygen deficiency during the nighttime. Some of the most effective and beneficiary cleaning plants for a pond are water lilies, watercress, water theme hornwort, and taro.

Plants provide nutrients and additional oxygen for the fish. And not only this, but it also serves as a natural filtration system and helps prevent the growth of algae.

Regular Pond Cleaning

Pond skimmers may help clean the debris on the pond. You can also clean the surface using a pond net to pick up any organic or inorganic things before they decompose and cause the increase of ammonia level in the pond water.

An increase in ammonia level is a big threat to a fish’s health as this can result in coma or death. The safe ammonia level for a fish is 0.001ppm to 0.020 ppm; above this, and ppm is considered dangerous.

Water Level

Do a regular check on the water level on your pond, especially during summer. Hot climate instantly drops the pond water level making it dangerous for marine life as this can starve them of oxygen.

As soon as you notice a drop of water level, immediately top up the water or establish water supply system.

Right Temperature

Wintertime lowers the water temperature. Use a heating system to maintain the exact and correct right temperature for the fish.

On the other hand, summertime causes the water to heat up. With this occurrence, put cold water or ice to the pond.

Well-Aerated Pond

To improve oxygen distribution and movement to the fish and the plants in the pond, you can install pond aerators – this also adds an aesthetic view to your pond.

Having a well-aerated pond is much better than having a motionless pond. A stagnant pond usually has a low oxygen level. Aerated ponds smell better as the movement of the water controls anaerobic bacteria that cause ponds to smell bad.

Tips On Making Your Pond Attractive

If you want to upscale your garden pond, here are some of my few tips.

Blend everything, but make sure that the fish and plants in the pond are still safe. You can landscape the whole pond and install some architectural designs to make it look more aesthetic.


You can add refined rocks as a landscape for your pond and plant beautiful plants. But make sure the plants you will be planting will not grow large enough to invade the pond—resort to planting a small type of plants that will contrast with any vegetation on the pond water.

Landscaping the pond is also a great way to cover up or hide the filtration system.

Architectural Designs

You can install architectural designs in your ponds, such as waterfalls or fountains. Not only will these add beauty to your pond, but they will also help with the water movement for your fish.

Benefits Of A Waterfall In Your Pond

Having a waterfall in your pond is a good thing. Not only does this add design to your garden pond and soothes the eyes, but its water aeration helps in the distribution of oxygen to both the fish and plants.

High oxygen level is very beneficial for various reasons. One being, if there’s a high oxygen level, algae would be having a much harder time growing. Secondly, this gives more oxygen to the fish.

This water aeration is also considered a great addition to your filtration system. It will help reduce bad pond odor caused by stagnant water.

Well Managed Fish Pond

Some of the advantages of having a pond can be significant depending on the purpose. Some build a pond for its aesthetic pleasure, and some for business and aquacultural purposes.

Proper knowledge in supervising a pond for both profit and recreational purposes can be enhanced and maintained for years to come.

Science has it that water gives a person a sense of ease – maybe because of how relaxing the sound is or how satisfying the view is. A fish, on the other hand, helps your overall wellbeing with its calm nature.

Managing a pond can also provide more food production for humans to consume.

Benefits Of Having A Pond

This reservoir is a great water conserver and an absolute improvement for the environment. With the help of the rain, ponds can naturally water themselves.

However, occasionally a pond needs to be topped off with water, especially during summertime or hot weather. But, it is mostly reliant on nature to help maintain a balanced and healthy ecosystem.

It is a great irrigation system. With a pond in your garden, it lowers the amount you spend on pesticides and fertilizers for your lawn – decreasing pollution and giving you more natural fresh air.

The paramount gain on having a pond is it indirectly braces wildlife that has an inadequate supply of needs in the suburban parts of the country.


A pond is an artificial lake created to either provide a beautiful view or food consumption for humans. But either way, it helps balance the ecosystem and create a sanctuary for some indigenous wildlife.

It is essential to use the safest and most trusted pond chemicals since some of the wildlife animals are dependent on the pond.
