Weird test results
So my 5gal tank has been cycling for the last 2 months now.
I'm not sure what's going on with the nitrite results.
For the last 2 days.. whenever I test nitrites... the color right from the start (as soon as the drops hit the water) is that dark purple color that would indicate that there are a lot of nitrites. But then within about 2-3min.. it goes to the blue 0 reading.
Anyone have this happen before and know what that means?
Test kit isn't expired and I'm definitely doing the testing correct.
I haven't changed the water in the tank in a while, so.. I dunno.. maybe that's messing with the results somehow?
