Tip from Simon: BACTA CLEAR + Oxygen Plants.

Oxygen plants are essential to any pond. They filter the water, reduce algae by blocking sunlight and remove the need for a pump or filter. In addition, they offer fish protection from danger. All of our hardy oxygen plants come with a 100% growth and flowering guarantee from our own nursery.

The best pond bacteria for the pond: BACTA CLEAR

In a pond, nitrifying bacteria are important. These bacteria help convert waste products into CO2. This is necessary for the growth of oxygen plants, which need CO2 to grow. BACTA CLEAR contains not 1 but 2 strain bacteria that both ensure clear water and prevent algae growth. In addition, BACTA CLEAR is 100% eco and not harmful to humans, plants and animals.

Benefits of bacteria in the pond

- 124 plants + bacteria
  • Ensure maintenance of clear water;
  • They help prevent algae growth;
  • Learn what steps must be met to successfully set up a pond
  • The bacteria combine excellently with pond substrate because they adhere to it;
  • They convert oxygen into carbon dioxide (CO2) so that oxygen plants grow better;
  • The microorganisms are environmentally friendly;
  • Pond bacteria contribute to improved water quality.

What are pond bacteria?

Pond bacteria are single-celled microorganisms that act as a natural filtration system in the water. They convert pollutants such as ammonium and nitrite into substances that are harmless to nature. If you add good quality pond bacteria, you also prevent algae growth in the water, and they reduce organic sludge on the pond floor. Sounds good, right?

Pond bacteria against algae

To keep the pond clean and clear, it is best to use BACTA CLEAR, a mixture of bacteria and enzymes developed by Simon. The product helps break down the residue, known as sludge, that forms on the bottom of the pond from excess fish food, trash, rotting leaves and dead algae. The recommended dosage is 1 liter of BACTA CLEAR for every 1,000 to 20,000 liters of pond water, and it is safe for humans, animals and plants. It is important to note that using the right mixture of bacteria will also help remove all debris, keeping the water clean and clear.

- Safe for human

How often do you add pond bacteria?

It is recommended to add pond bacteria twice a year; once in the spring to start up the pond, or after pond construction and once in the fall to help the pond get through the winter. This helps the biological filter work properly and gives the oxygen plants an extra boost in the spring. It is recommended to add additional pond substrate at the same time in the spring, this will help pond plants grow better.

The usefulness of pond substrate in combination with pond bacteria

The combination of pond bacteria and substrate is an important part of maintaining a healthy pond. Bacteria break down waste products and convert them into useful substances for plants. The substrate acts as a growth and reproductive surface for the bacteria, increases efficiency in waste treatment and limits unwanted algae growth. The substrate also serves as a natural filter and can lead to richer biodiversity in the pond.

Frequently asked questions about pond bacteria

Pond Advice

In a pond, nitrifying bacteria are important. These bacteria help convert waste products into CO2. This is necessary for the growth of oxygen plants, which need CO2 to grow. Bacta Clear pond bacteria was specially developed by aquatic plant grower and pond specialist Simon and is the only liquid agent you need to keep a pond healthy if the pond is properly set up.

To maintain the natural habitat of a pond, it is recommended to add bacteria regularly. This is best done in spring, when the temperature rises above 12°C. After every pond maintenance, the right amount of microorganisms should be added to maintain the balance.

Some bacteria can get into our illness, such as from outside or from insufficiently cooking a piece of meat such as chicken. Bacteria that people can get food poisoning from are: Salmonella, E. coli O157 and Campylobacter.

Nitrifying bacteria are the same as pond bacteria. The organisms attach to pond substrate on the bottom of a pond and to the roots of aquatic plants. They convert pollutants (nitrite and nitrate, for example) into CO2, which is a nutrient for oxygen plants. Without CO2, your oxygen plants can suffocate in the pond. But thanks to the addition of nitrifying bacteria or pond bacteria and sufficient oxygen plants, they keep each other in balance and the water stays nice and clear.
