Best Aquarium Testing Supplies

PetGuide logo

Dogs, cats, and other traditional pets interact with their owners on a daily basis. Over time, you get a feel for your pet’s personality and you can easily tell when something is wrong. Aquarium fish are not the kind of pet you typically interact with, and they don’t have as much personality. This makes it tricky to know when something in the tank isn’t quite right. So, what do you do?

As an aquarium hobbyist, it is your responsibility to make sure your tank is set up to provide for the needs of your aquarium fish. Different species have different requirements, so the only way to know whether your tank is within the proper parameters is to test the tank water. Read on to learn more about testing your aquarium water and to see our recommendations for testing supplies.

Maintaining high water quality in your tank is essential for the health and wellness of your fish. As waste products break down, they produce ammonia which is then broken down into nitrite. This test kit helps you quickly and accurately test nitrite levels in your tank so you can fix high levels with a water change, if needed.

Tips for Testing Your Aquarium Water

When it comes to maintaining a home aquarium, there are a number of elements you need to keep track of. In addition to keeping the tank at a stable temperature, you also need to think about things like ammonia levels, water hardness, pH level, and more. The only way to keep track of these parameters is to test your tank water on a regular basis.

Here are some tips for testing your aquarium water:

  • Take some time to research the species of fish in your tank and learn their requirements for different aspects of aquarium water chemistry.
  • Start with aquarium water test strips – they are the simplest testing method to use because you simply dip them in a water sample.
  • Test your aquarium water once a week and record the results in a notebook – this will help you establish the “normal” levels for your tank so you can spot a problem if something changes.
  • Once you get the hang of aquarium test strips, you might want to upgrade to a more comprehensive test kit so you can get more specific results.
  • Make adjustments to your aquarium water chemistry as needed, indicated by the results of your weekly testing.
  • If you notice your aquarium fish exhibiting signs of stress (such as flashing, gaping, or lolling on the bottom of the tank), test your water to see if it is an issue with the tank chemistry.

Your home aquarium is a captive environment in which your fish spend their entire lives. Use the testing equipment we’ve recommended above to ensure that the conditions in your tank stay within the proper limits to keep your fish happy and healthy.
