API Nitrate Test Kit for Fresh or Saltwater

This test kit can be tricky to match to the provided color chart. It will likely be a shade of orange, but they are very similar unless you have 0 nitrate or a ton. Also kind of annoying to have to vigorously shake both the reagent and the test tube for 30 and 60 seconds but maybe all nitrate tests require this? The test tube and lid always leak a bit when I shake them, even when I hold the lid down.

Have used this test kit before and found that AQUACAVE wants the customer's business with their price match program, competitive pricing and awesome turnaround with shipping.

I have tried several nitrate test kits but keep going back to API nitrate test kit. As always, Aquacave has great service, prices and selection, fast shipping.
