White residue on my live rock ID

[xlLostlx]

Could anyone tell me what's the residue on my rock?

Hmm almost looks like the population of early bacteria possibly? Is this a cycling tank?

 

[xlLostlx]

Yes, Ive been doing small ghost feedings every 2-3 days as well.

During cycling it’s common to see all kinds of odd stuff come and go, varying tank to tank. Are you running the lights during your cycle?

Occasionally, after a week cycle of ghost feedings I added a hermit and emerald crab, did a water change so since Sunday the lights been on for a few hours at a time during the day. Off at night.
