Quote by Dmill15: You asked earlier what kind of test kit I had it is an Aquarium Pharmaceuticals saltwater masters. Just re-checked everything again and nothing has changed.
Make sure you follow the nitrate test instructions to the T. There is alot of vigorous shaking and waiting involved in the test. If it is not done correctly you will have a lower reading than what is present.
Happened to me once. I knew something was wrong, but all my tests were good, so I brought some water to the LFS and the nitrates were 40ppm. They tested 10ppm with that kit! He used a Salifert kit.
Not saying that your nitrates are wong, just be specific to the instructions when testing. I guess I wasn't shaking long enough or waiting long enough. Either way, it was a mess.
Good Luck, Frank
