Nitrite on test Tetra SW test strip
what does this color mean? This is an established tank caked with all colors of coraline.

Invisible is a great color to have..
 Those strips are hardly regarded as extremely accurate so I really wouldn't worry about a nitrite reading with one on an established tank.. Its just highly unlikely to be a real problem..

Guessing based on the online chart, I'd say that was either zero, or the test kit has failed. Most setups will reach zero nitrite fairly quickly. Is there a problem you're trying to solve, or are you starting a new system?
