Watertests

eSHa Aqua-Quick-Test contains 50 Test strips = 250 single tests for the quick and exact determination of pH value, total hardness (GH/TH), carbonate hardness (KH), nitrite (NO²) and nitrate (NO³) in freshwater aquaria or garden pond.

The Aquavital multitest 6in1 allows you to quickly, easily and reliably determine the 6 most important parameters for fresh water: pH, total hardness (GH), carbonate hardness (KH), nitrite (NO2), nitrate (NO3) and chlorine (Cl2).

The Colombo GH Test kit measures the total amount of minerals dissolved in water. All the dissolved minerals that determine the 'hardness' of the water are essential for the biological processes that occur in your aquarium or pond. If the hardness is too

The Colombo PH Test Kit measures the pH value to denote whether water is acidic, neutral or basic. If the water is too acidic or basic, this can quickly result in the death of fish.

The degradation or mineralisation process of all organic substances in the aquarium and pond follows these stages: proteins > ammonium > nitrite > nitrate. By measuring these stages conclusions can be drawn about the “functioning” of the systems aquarium

Determines optimal nitrate value for perfect plant growth or possible cause of algae growth in freshwater & marine water.

Nitrite results during the degradation by bacteria of protein and ammonium. It is normally processed further into non-toxic nitrate. In aquarium and pond water nitrite (NO2) should not be measurable.

The well-being of aquarium and pond dwellers and the growth of aquatic plants depend to a large extent on the pH level being kept as constant as possible.

In an aquarium, phosphate primarily enters the water as a result of the digestive processes of the fish or in the form of food remains. In ponds, phosphate primarily enters the water as a result of leaves and dying pond plants/algae.
