Velda Aqua Test Set pH-gH-kH

With the Aqua Tests from Velda, the quality of pond and aquarium water can be determined quickly and accurately. A handy tool for this is the Pond Test App for smartphone or tablet. After entering the values found, you will receive a clear pond diagnosis and improvement tips from Velda, tailored to your own pond situation. The test results are saved to gain insight into the development of the pond environment. pH Test measures the acidity of fresh and salt water using the color scale and comparator. A pH above 8.5 stagnates plant growth and a value below 7 is harmful to fish. GH Test measures the collective hardness of freshwater with an accuracy of 1 °DH. A GH value of less than 8 °DH stagnates plant growth and can cause acidification, especially in winter. KH Test measures the carbonate hardness of fresh and salt water with an accuracy of 1 °DH. A KH value less than 6 °DH indicates acidification and inhibits the growth of oxygenating plants.

JBL Test Combi Set Plus NH4

Healthy aquarium with natural proportions The correct water values in an aquarium depend on the fish stock and the plants present. Even when the water looks clear it can be polluted. Incorrect values can cause diseases and algae in the aquarium. Regular monitoring and, if necessary, adjustment of the water values is important for a healthy aquarium with natural proportions. With the JBL water tests you can determine all relevant water values quickly, simply and very accurately. Simple and reliable control of water values in aquariums. Determination of: pH value, carbonate hardness, nitrite, nitrate and ammonium/ammonia and CO2 calculation via table Easy to use: Fill aquarium water with a syringe into a cuvette, add the indicator and compare the color with the color scale or count the number of drops to the color change during the KH test The natural color of the water is taken into account by the comparator system. The CO2 content is determined by means of the pH and KH value in the table Child-resistant reagent bottles and water-resistant plastic case. Refilling reagents available separately Contents: 1 aquarium test case with 9 reagents, 3 glass cuvettes, syringe, dosing spoon, comparator block, plastic cuvette, color cards, protocol sheets and user manual To determine the CO2 content, measuring the pH and KH is sufficient.

Colombo PH Test

Colombo PH test can be used to accurately determine the pH value of the water in your pond. The pH is an arithmetic indication for the amount of acid in pond water. The water can have a pH value that varies between 0 and 14, whereby the lower the value of the water, the more acidic the pond water. Large fluctuations in the pH value are harmful to the fish. This can have disastrous consequences, especially at the start of a filter. It is wise to test at least 2 x a week for the first time. Then you should check the values of PH, GH, KH NO2, NO3 and NH3 monthly. The pack contains 25 tests. Optimal water values: pH value: 7-8 GH value: 8-12 KH value: 5-12 Ammonia (NH3) < 0.15 mg/l Nitrite (NO2) < 0.15 mg/l Nitrate (NO3) < 0.50 mg/l Oxygen (O2) 60%- 100%

Copper test strip (50st)

An ideal en effective method against (blanket)weed. The Copper Electrolyser is installed before the (swim)pond return inlet. The pond water flows through the Copper Electrolyser unit. A copper unit, or Electrolyser, is positioned within the housing, and the copper unit discharges a minimal amount of copper into the water flowing through the housing. These copper ions (Cu2+) in the water have a positive charge and destroy the cell walls of algae, bacteria, viruses and other primitive organisms. As the cell wall is thereby damaged, these organisms are no longer able to take up any nutrients, and are therefore unable to multiply. The process of applying a positive charge to copper is called copper electrolysis. Inlet/outlet: Ø50mm. PLEASE NOTE: (too much) copper is harmful for fish! After 2 weeks the unit will automatically switch off. Test the copper level in the water and activate the unit again if necessary. This will prevent the build-up of too much copper in the water. Not to use in water that contains iron (like ground water).
