diatom, or brown hair algae?

[mp32]

I added about 20lbs of live rock to my tank and it started cycling. I am getting a brown algae growth and it looks like small stringy threads comming out of it. It is on the sand, and the rock, and it is spreading everywhere. I know diatoms are normal for a cycle but do they have the stringy stuff comming out of it, or is this hair algae? That is what is making me wonder what it is. i do not have pictures and I am not home for 3 days, so all I can do is give a description. Thanks in advance.

I had this same problem. The Diatoms are normal. After that it might go into a cyanobacteria phase. It starts to get stringy and bubbles start to come out of it.....small bubbles. Maybe even after that you might go through a hair algae phase. It will all go away. You can syphon some of it off the rocks to help it but it will go away once it uses up its source. The source being silica. All new tanks have it. In the meantime have a little patience.

Yep, that is what it is doing stringy stuff with bubbles. Just wanted to identify it. Thanks
