    What is the most important test for an aquarium?

    The most important tests for an aquarium are for ammonia, nitrite and nitrate. These are key indicators of water quality and the nitrogen cycle, both of which are crucial for fish health. 

    Are aquarium test strips worth it?

    Whilst they can be useful for quickly checking basic water parameters, test strips can vary in quality and are generally less accurate than liquid test kits. They are simple to use, convenient and quick, but you may need something more reliable if you have a more sensitive or complex setup. 

    What is the best test strip for aquarium water?

    API 5-in-1 test strips are generally considered the best, as they cover all the basic parameters required for a freshwater aquarium. Made by one of the best-known brands in the aquarium world, these test strips are affordable and ideal for beginners. 

    How long do aquarium test kits last?

    Both liquid kits and test strips degrade over time. Liquid kits generally last between one and three years, while test strips are around one or two. Storing both types of kit in a cool, dry place generally helps with longevity, so be sure to check the storage guidance on the packet when you purchase.
