The API NITRATE 90-Test is an easy-to-use kit that monitors the nitrate level in your aquarium water. The kit comes with a USB cable, a small bottle of water, and a fish food treat. The water monitor measures nitrate levels in parts per million (ppm). The higher the number, the more harmful the water is for your fish. The nitrate test results are also used to help determine which fish foods are safe for your fish.
