At Aquario.pl you will find professional tests for aquarium water that do not require aquarists to have knowledge of chemistry. With basic knowledge of pH, hardness, and water composition, we can react in time by performing water changes, using appropriate fertilizers, or deciding to replace the filter media. Regularly performed aquarium tests can save the fauna and flora in our aquarium. In our shop, there are several types of tests available that should be used regularly—especially if we are just starting our adventure with aquaristics. For such individuals, we recommend purchasing a test kit that, when combined with an app, will help analyze the results immediately. If you want to measure a specific parameter, it's worth reaching for drop tests, strip tests, or using electronic measurement devices. Electronic water tests in the aquarium are particularly recommended for large tanks. Their purpose is to quickly detect harmful compounds for fish and decorative plants, such as phosphates and nitrates, as well as to measure water hardness and pH. Electric meters are excellent devices for forgetful individuals who often forget to buy new strip or drop tests. For such people, a great solution is to permanently place a strip test in the aquarium or in the filter. The permanent filter, by changing color, informs us of the detection of harmful compounds in the water and can work even for an entire year.
