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).

Ammonia (NH3) is excreted by fish directly into the water, and is also released from the breakdown of solid waste and uneaten food. Ammonia is highly toxic to fish, but is usually removed from the water by the bacteria which live inside the filter.The onl

Colombo GH Plus increases the levels of salts and minerals in your planted aquarium. The reason why salts and minerals are added is to improve the health of fish and plants. Over time these minerals become depleted over time which is why it's necessary to

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 KH Test Kit also called carbonate hardness or temporary hardness is formed by binding of calcium with carbon dioxide.This binding is important for the buffering of the pH in the aquarium or pond.

Colombo NO3 Test Kit measures Nitrate(NO3) which is produced by useful Nitrifying bacteria in filters of aquariums or ponds during the decomposition of toxic waste(ammonia and nitrite).Nitrate is not toxic for the fish in your aquarium or pond but too hig

Colombo No2 Test kit measures Nitrite (NO2) which is produced by useful bacteria during the decomposition of ammonia waste secreted by the fish. Nitrite can adversely affect the health of your fish, even when it is present in low concentrations. Nitrite i

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 Colombo Quick Test 6-in-1 you can measure quickly and easily six major water's value. The quick test strip can be pH - determine Nitrite and Nitrate value - KH - GH and CL2. Dip the test strip for 1 second into the water. Remove the strip from the wat

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.
