Always wondered what Microbe-Lift bacteria can do for you and your pond? This "Brouwershaven" project shows you the difference between a pond that has not undergone treatment and a pond that has been treated with Microbe-Lift pond bacteria.

The reason for this treatment was that the water was dirty, stank, and fish mortality occurred, which ultimately led to the recreation park receiving negative reviews.

This project involved a pond of 1.5 million liter water water, where over a period of 6 months (May - November) 92 liters of Microbe-Lift Clean & Clear and 92 liters of Microbe-Lift Sludge Away were added.

Product Content – Pond Zinger Flocculant/Phosphate Remover – AquaForte

Pond Zinger Flocculant/Phosphate Remover is a powerful and targeted water treatment product specially developed to quickly and effectively remove phosphates and suspended dirt particles from pond water. This targeted approach structurally limits the main nutrient source for algae, resulting in clearer water and a better manageable pond environment.

The flocculating action of Pond Zinger causes fine suspended particles, which normally continue to circulate through the filter system, to clump together into larger particles. These can then easily be mechanically filtered out or settle, quickly improving the visual clarity of the water. At the same time, the product binds phosphates, which are responsible for unwanted algae growth and water pollution.

Pond Zinger is suitable for both ornamental ponds and koi ponds and can be used for acute water problems, seasonal startup, or as part of regular maintenance. The product works correctively and preventively and supports a stable water quality without disrupting the biological balance.

Thanks to the controlled composition, Pond Zinger is safe for fish, plants, and beneficial bacteria, provided it is used according to the guidelines. Its use reduces the need for intensive interventions and increases the efficiency of existing filter systems.

Application Benefits

The Colombo KH Test is an accurate and user-friendly test kit for measuring the carbonate hardness (KH) in pond water. The KH value is one of the most important parameters in the pond, because it determines the buffering capacity of the water. This means that the KH value directly affects the stability of the pH value.

A KH value that is too low can lead to strong pH fluctuations, which causes stress and health problems in fish. Furthermore, beneficial bacteria that break down waste products such as ammonia and nitrite function less effectively at an unstable pH. The result is that the water quality deteriorates, which can lead to cloudy water, algae growth, and an unhealthy pond environment.

With the Colombo KH Test, you can easily and reliably check whether the KH value in your pond is at the right level. The test is easy to use: with a water sample and the included reagents, you can read the result within a few minutes. The clear color comparison makes it possible to quickly determine whether the KH value is correct or whether adjustment with a product such as Colombo KH+ is necessary.

By regularly testing the KH value, you prevent problems and ensure a stable and healthy environment in which fish, plants, and bacteria function optimally. This contributes not only to better water quality, but also to clear water and a balanced pond.

The Colombo KH Test is therefore an indispensable tool for both beginner and experienced pond enthusiasts. It helps you keep the water quality under control and gives you the assurance that your pond remains balanced, so that you can fully enjoy healthy fish and a beautiful pond.
