Main highlights
【 SUITABLE FOR FRESHWATER AQUARIUMS 】: The main factor in successful fish keeping and health lies in the maintenance of good water quality. Ammonia, nitrite and pH levels in the aquarium should be checked regularly and our test kit makes it fun and simple to do so. This test kit reports concentration in terms of nitrogen (NH3-N), (NO2-N) or (NO3-N) to ensure compatibility with reported safe concentrations as they apply to fish and plants. The test kit is suitable for use in freshwater aquariums.
【 EASY TO USE 】: Full instructions are included, detailing optimum levels of the 6 key parameters and suggestions for correction, along with an integrated test tube rack. Simply add your aquarium water to the test tube and count the number of drops needed. The back of the box details clear pictorial instructions and a set of colour coded stickers is provided to label both the test tubes and test tube lids, so you always conduct the same test in the same test tube, avoiding contamination.
【 COMPACT & PORTABLE 】: The test kit is packaged in a compact cardboard box, providing convenience when conducting the tests, as well as when storing the tests. This guarantees a quick and easy response when your aquarium water needs testing.
【 ACCURATE LIQUID DROP TESTS 】: All the tests are liquid drop tests from a dropper bottle to ensure the drops are the same size. This method of testing is significantly more precise compared to using dip strips. The use of liquid reagents guarantees accurate and dependable results for each parameter, simplifying the process of monitoring and maintaining ideal water conditions in your aquarium.
【 6 IN 1 TEST KIT 】: Our multi-test kit enables aquarium owners to effortlessly assess six key water parameters using a single test kit, including Ammonia, Nitrite, Nitrate, pH, General Hardness (GH) and Carbonate Hardness (KH).
