Cycling question

[JTrigger]

So after my tank crashed I spent the whole next day with a friend setting it back up.. it's back up and running, things look good, just barren... I ended up taking out about 75% of the water, left the sandbed and rock... added new RO with salt and took some readings:

pH 8.0
NH4 1.0
NO3 0
NO2 0

So does this mean it's just starting a new cycle or will it have to cycle again despite having the same DSB/LR or? I'm just a lil confused.
