Have been up and running the 40 gal fish-live rock-reef tank for about a month. Have blue tang, clowns and some coral.

Just started to notice brown substance "growing" in spots on the rock. Is it algae ? Bad?

Diatoms is something all new tanks go thru. You'll see it on rock, sand, heater, and glass. It'll pass almost as quick as it appeared.
