IMO, nitrite is not something reefers need to be concerned with or measure.
Is it toxic at high levels (like 150 ppm)? Very likely yes. Published studies claim so, but I personally would not be sure that a study adding 150 ppm nitrite didn't accidentally have 0.5 ppm ammonia also present.
But is it ever toxic in a cycled reef aquarium? Highly unlikely, IMO, without dosing nitrite.
Is it ever toxic in any reef tank that can process ammonia? I cannot see how unless one set up a system to process a ton of ammonia fast before nitrite processing got ramped up.
