While it's possible to use the best pool test kits for your aquariums, it's not the best option. Guess why? Because these swimming strips don't provide accurate test results for ph, ammonia, nitrite, and nitrate levels. 

For this reason, it's appropriate to stick with test strips specifically designed to check the water quality of freshwater tanks. Read our guide to choose a pool store test kit that is good for your aquarium.

Testing aquarium water is one of the most important things you can do to ensure the health of your fish. But why is it essential to sample the water in the first place? Testing the hardness of your tank’s water can help identify potential problems before they become serious. 

For example, if the ammonia levels in your tank or tap water are high, this could be toxic to your fish and cause them to fall ill. The water tank test paper will significantly help you evaluate different water parameters, including pH, ammonia, and nitrate. 

And here are a few tips to consider before you start using water test kits in a tank. 

    • Make sure you're using a reputable brand 
    • Test water quality regularly 
    • Every test kit is different, so follow the instructions carefully 
    • You should only use a fish tank testing kit with a long shelf life 
    • Don’t test the water weekly or monthly, but be consistent to spot problems quickly 
    • Determine whether it is designed to be used with basic freshwater, saltwater, or both 
    • Have your water’s total alkalinity tested by a professional at least once a year. 

How Long Do Aquarium Test Kits Last?

You might be wondering - do pool test kits expire? Of course, they do, and so do aquarium test kits. 

If you see an expiration date, that date refers to the shelf life of the entire kit. The expiration date is usually printed on the back of the test strip box or stamped on the bottom of the bottle. Once you have passed that date, the kit may not provide reliable results.
