Description

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 aquarium help fish owners measure levels of Nitrite, Nitrate, Carbonate & General Hardness, and pH found in aquarium water.

    • Good Test Strips - Helps Use Gauge How Healthy Our Betta's Tank Is
Size: 25-Count Style: Aquarium Water Testing
The API Test Strips are a good water monitoring system for small tanks. We've owned our betta for a little over 2 months now, and the API strips have helped us keep our small tank's water at the proper level for our fish to thrive. We check the water every other week or so and it helps us make the small adjustments to ensure our fish isn't getting sick. The strips are fairly easy to read, come up with results almost instantaneously, and seem to be accurate. While they may not work well for larger set ups, they work perfectly for our small tank set up and are helping us get a better idea of how to maintain the water. Overall good value for a small hobbyist aquarium owner. ... show more

    • Doesn't tell as much as others
Size: 25-Count Style: Aquarium Water Testing
My first-ever testing strips, would say whether or not the parameters in my water, were safe for the fish. So I thought that's how they all came. I was shocked to discover that this one only gives numbers! Readings. It doesn't say whether or not they are safe parameters for the fish! So it was basically a waste of money for me. ... show more
