We propose planting three bunches of oxygenating plants per m2 at Pond Plants HQ. For example, if your pond is a 2m by 4m rectangle, its size will be around 8m2. As a result, you'll need 24 bunches of oxygenating plants. It's important to choose plants that are appropriate for your pond environment and that will grow well in your location. We provide more information on the types of plants that will help improve the quality of your water below.
Of course, this is only a guide. The amount of oxygenating plants you need depends on several factors such as how much fish activity there is in your pond, the amount of pollution it receives, etc. However, we think this is a good start!

The submerged foliage of oxygenating plants generates oxygen throughout the day, maintaining the pond's biological equilibrium. Insects, frogs, newts, and young fish can all find refuge in oxygenating plants. The plants take in carbon dioxide during the night and release it during the day, helping to keep concentrations even across the pool.
The amount of oxygen generated by plants varies depending on the species and size of plant. Smaller plants such as duckweed and water hyacinth release more oxygen than larger plants like water lilies and hydrangeas. Also, deciduous plants such as willows and alders release more oxygen than evergreen plants like cryptomeria trees. Finally, floating plants like water lilies and hydrangeas release more oxygen at night when photosynthesis is not possible so they can catch up on their sleep during the day when the sun is out.
Oxygenating plants help to maintain an ideal environment for aquatic animals by reducing the amount of toxic substances in the water. These poisonous chemicals include ammonia, hydrogen sulfide, and methylmercury. Animals that live in ponds or lakes have evolved ways to protect themselves from these chemicals. For example, fish have special proteins in their blood that bind to mercury so it cannot harm them.
Then, using the following calculations, determine the size of your pond: (Gallons) Square/Rectangular: Assume the pond is 8 feet by 4 feet and 2 feet deep on average. Add 7.48 gallons per cubic foot to the average length (feet) by the average width (feet) by the average water depth (feet). Then divide that number by 1,813.20 to find the total gallonage needed for your pool.
Circular: Assume the pond is also 8 feet in diameter and 2 feet deep on average. It will take between 100 and 120 square feet of pond surface area to hold the same amount of water as the rectangular pond.
Now, using the following formula, figure out the volume of water in acres: (Gallons) / (Feet * Feet * Years) Avogadro's Number: The number of particles in one mole is 6.0221407(20), so if you know how many moles are in an acre then you can calculate how much water is in an acre. One mole contains 22.4 grams, so one acre contains 3,500 meters squared (or 3.5 million centimeters squared).
Knowing the volume of water in acres, you can now calculate the amount of water needed for your pond by multiplying the number of acres by the capacity of the pond in gallons per acre, which you got from the first question.
