What are fish tank test kits?

Fish tank test kits are simply kits that help you test your aquarium water. They can measure things like water pH, salinity, chlorine, ammonia levels, and more. You can find everything from simple test strips to advanced master kits and meters.

Are aquarium water test strips accurate?

Aquarium water test strips can be somewhat accurate, but they are not as reliable as liquid test kits or professional testing. Test strips are easy to use and—if you choose a quality brand—good for getting a general sense of certain water parameters. However, if you need more precise measurements, liquid test kits are usually better.
