Nitrite

[Justin1982]

What would cause a random Nitrite bloom? Enough to kill every fish. Over night it jumped from 0 to off the chart; >5ppm. Ammonia is at 0, nitrate <5ppm. Ph 8.0. Specific gravity is at 1.025. Temp 79.8. Granted I'm testing these parameters after the dead fish sat at the bottom for over 10 hours and I'm sure there has already been some decay. Corals and inverts are still alive.

Oh, and I forgot to add, this is not a feshly cycled tank. It has been active for over a year now with only 1 fish dying in the entire time its had life.

My thought is that something else killed everything and the high nitrite is a result of that, not the cause.
Soon the nitrate will be high.
