So long story short, why am I showing no nitrates and should I be doing a water change?I am linking this thread right now to page one of the microbiology of cycling thread, any reef tank can show zero nitrates it has nothing to do with your cycle.
In that thread we demonstrate using examples like yours that ammonia control is the only param we need to know, to begin reefing. Nitrite is fully neutral in marine aquariums anyway, no need to test for it. Can't harm a system even if it's there, nitrite always catches up in time regardless of start date for a reef tank. Nitrate, as you show, may or may not even show up but your tank keeps fish alive past ten hours because its 100% cycled.
To cycle an aquarium, we only have to measure (or demonstrate) that ammonia is controlled. Excellent thread you have here.
