Hi guys, I'm new to saltwater and I'm cycling my tank at the moment, don't have much in it apart from a few rocks, anyway I noticed some tiny things growing on some of the rocks and also some other stuff. Are they okay being in there or should I remove them and if so, how? When I went to get my rocks from Organism, John cut out something which resembled what's in my tank and he said that I don't want them in there.
Apologies if pictures don't show, first time trying to attach pics and also sorry for cellphone pics
Thanks guys!
