I know it doesn't make sense, but my ammonia is at 0.25 and i'm not showing nitrites yet. Tank is 80Gal. Here is what I've done:
Dec 21--cleaned tank with 50/50 RO
water/vinegar mix. Rinsed base rock in de-chlorinated tap water and then in RO
Dec 22-- Filled tank with RO
and running carbon in filter, heater and both powerheads. Added salt to get 1.023.
Dec 23-- Added 4 bags aragalive fiji pink and 40lbs reefrocks.net sand. Removed carbon and used 2 little packets of bio-magnet clarifier that came with the aragalive sand. Added 50 drops pure ammonia to reach 8.0ppm.
Dec 24-- cleaned filter and media because of fine sediment buildup from new sand. added another 5 drops ammonia. Still at 8.0ppm. Started up skimmer.
Dec 25-- Water is fairly clear. Ammonia has dropped to between 4.0-8.0ppm. Added another 5 drops pure ammonia. Salt still at 1.023.
Dec 26-- Water is super clear. Ammonia between 2.0-4.0ppm. Added 5 drops ammonia again.
Dec 27-- Ammonia at 0.25. Tested for Nitrites but nothing yet. Added 5 drops ammonia.
Havent tested today yet. I know the AragAlive sand says fish can be added immediately, could it be that the live bacteria has led
to the fast cycle? Skimmer is pulling out dissolved organics already.

Looking for some peoples thoughts. I'll continue testing daily and hopefully will see nitrites soon.
