Hello everyone! New to reefing and finished cycling my tanks roughly two weeks ago now. On about week 6-7 of this new tank and saw these brown spots on my rocks, but nothing on the sand bed. I know I am supposed to prepare myself for diatoms, but these do not look like them based on pictures I have looked at. Any help on what these might be would be great. Also can I attack the problem now and get rid of them? If so what is the best method?
Thanks for all the help!
