White fuzzyish stuff on live rock

[Tx Medic]

I have a 29 gallon lps and softies tank that has been up for a about 4 months and this stuff has been growing for a while mostly on the underside of my rock and has started to grow on the top now. All my parameters are good cept minimal nitrate. Just want to know what it is. It seems to be growing quicker lately.

I don't know :( It almost looks like a branching macro but the white color rules that out.....bump for your question!
