Quick answer

Cycle a beginner reef tank by keeping salinity at 1.025 to 1.026 and temperature at 77 to 79F while avoiding sudden changes. The key checkpoint is stability, not chasing rapid adjustments, and logging trends helps you see whether the tank is settling before adding livestock. Monitor parameters consistently through the cycle.
