Colombo Algadrex Against Green Water - 500 ml
Colombo Algadrex, Control of floating algae. In the pond, problems are usually caused by floating algae. These make the water green and opaque.

By applying Algadrex, after a few hours, the water will become clearer again. the clumped algae float on the water surface, sink to the bottom or end up in the filter. Since they form an organic burden on the pond environment, it is recommended to remove them as much as possible using a scoop net and by cleaning the filter. Dosage: 100 ml per 1,000 liters of pond water. Before each treatment, first test all water values and in particular the KH value.

Colombo BiOx Prevents Thread Algae - 1,000 ml
Colombo BiOx Prevents Thread Algae - 1,000 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 Bio-Oxidator - 5,000 ml
Velda Bio-Oxidator - 5,000 ml
Leaf litter, plant remains and fish droppings can seriously contaminate the pond floor. Especially under low-oxygen conditions, the bottom layer will acidify and bacterial conversion of organic bottom sludge is no longer possible. This seriously affects the pond environment. The aquatic plants stop growing and algae take over. Bio-Oxydator removes pond bottom sludge and prevents new sludge formation. Available in packs of 1000, 2500 and 5000 ml. With the help of three active ingredients, Bio-Oxydator tackles the bottom sludge: The pH-regulating granules ensure that the soil layer does not acidify. The slowly dissolving natural lime ensures the correct water hardness in the bottom zone. The added micro-organisms (in freeze-dried form) immediately start the bacterial conversion of the soil waste. With Bio-Oxydator, the bottom sludge will disappear in a short time. Apply mainly in early spring and autumn.

Sludge Away is particularly suitable for ponds with a substrate bottom and where bottom suckers are difficult to use. Works faster in warm water temperatures but can be used all year round. Dosage: Basic dose = 100ml per 1250 liters of pond water. First month 100ml per 1250 liters of pond water per week, then 1 x per month (if necessary) 100ml per 1250 liters of pond water. TIP!
