Keep your fish healthy and thriving by testing your aquarium water regularly with easy-to-use API 5-in-1 TEST STRIPS. API 5-in-1 TEST STRIPS for freshwater and saltwater aquariums help fish owners measure levels of Nitrite, Nitrate, Carbonate & General Hardness, and pH found in aquarium water. In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness, and even death. Just dip a strip directly into your aquarium and use the color-coded chart to determine if your water is safe, or if adjustments are needed. Then follow the recommendations to treat the water – it’s that simple. In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness, and even loss. The most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium.

[This review was collected as part of a promotion.] Good when you need a fast easy way of making sure your tanks water is safe - especially when fish seem “off” or sick.

[This review was collected as part of a promotion.] I'm new to fish keeping, but this is essential to making sure your water parameters are safe to raise %26 keep healthy happy fish. Remember to keep in a dry place and use whenever you're unsure about the water in your aquarium. You won't regret purchasing it's an absolute necessity.

Must have for fish keeping!

These strips are easy to use -- just dip one in the water and compare to the color chart.  The chart is right on the canister, so it doesn't get lost.  (Be sure to mark the ideal measurement on the canister so it will be handy.)  The info in the package explains the results and what to do next in a clear way.   It was a real eye-opener for me -- now I know why I could never keep the pH right.

East to use

[This review was collected as part of a promotion.] Definitely will be buying the bigger version but they are easy to use and read.

easy to read love them

User friendly packaging with the reading levels in the outside.

Great product.

We are very glad to have this service. It helps us to be a little bit independent.

[This review was collected as part of a promotion.] Too complicated to read, had to look up all the values. Will forever use Tetra 5-1 instead of these

Tetra test strips are way easier to read
