Colombo BiOx Prevents Thread Algae - 2,500 ml
Colombo BiOx prevents the growth of thread algae and cleans your pond. Colombo BiOx cleans your pond with active oxygen and combats thread algae in a natural way. When BiOx comes into contact with the water, active oxygen is immediately released. Oxygen is an important factor in the environment of your pond, because bacteria in the pond filter use oxygen to decompose waste. In addition, improved oxygen saturation contributes to the performance of your biological filter. The high oxygen levels make it easier for your fish to get the oxygen they need from the water. Due to the strong natural oxidation power of BiOx, organic pollution and sludge is broken down and filamentous algae are combated. By using BiOx weekly, your pond stays clean and you keep thread algae away. Dosage/Use Weekly, 1 scoop (=150 ml) per 5,000 liters of pond water (For example: with 1,000 ml Colombo BiOx you treat 17,500 liters of pond water during 5 weeks). Never pour directly on the plants. Good water quality is essential for a healthy pond and therefore healthy fish. Therefore, test the water quality at least once a month and correct where necessary. The KH is especially important: it should be between 6 and 8°DH before starting the treatment. For use in ornamental ponds only. Keep in the container and out of the reach of children between 4 and 32°C. Tip: Use Colombo Algisin to combat stubborn thread algae. After that, the development of thread algae can be prevented by using BiOx.

Velda CO2 Tablets
In nature, CO 2 (carbon dioxide) is a primary nutrient for almost all plant organisms. This applies to plants that grow on land, but certainly also to aquatic plants. Under the influence of (sun) light, the plants absorb CO 2 and convert it into sugars, which are necessary for growth. CO 2 is therefore a very important factor in the development of pond plants. The contents of the container is sufficient to deal with 4000 liters of pond water with CO 2.
