White Fuzz

[NEWSALT]

I've noticed this white "peach fuzz" growth on some of my LR:

It's short and does not come off easily. It's not on the glass or the sand. It's only on some of the LR, the overflows, and powerheads. I have been dosing Brightwell's MicroBacter7, Vodka and RowaPhos. I stopped dosing MB7 and Vodka today to see if either of those are the cause. Maybe the combination of MB7, Vodka and RowaPhos is the problem. ??? Has anyone ever seen anything like this?

I have noticed that on my rocks as well, but usually on the underside, never on the top in the light.. It comes and goes and does no harm that I have ever witnessed.. I dose brightwell liquid reef and use seachem reef salt. My rock originally came from Dr Mac.
