Lotsa things can cause Nitra spikes most common from what I've read on this site -
- In fequent water changes (nitra build up)
-Chlorimine in the tapwater (nitra in tapwater)
- water changes w/ cold water (cycle crash)
- Not changing the carbon frequent enuff (back spill of nitra when carbon is shot)
- Changing media to frequently (re-cycle)
- Dead fish
