I noticed today when I came home from work that I have what appears to be snow growing on my new live rock. Is this a good thing or should I brush it off?
Current tank readings are as follows; tank been setup for around 70 days.

I am starting to use RO
water, but just got the unit hooked up last week. So this will be my first week using RO
water as my water change. Prior to that I was using water from the tap that was circulated in a barrel for a week.
