Hi all I have recently got about 30lb of LR from a friend which was getting rid of his old tank the LR was fully cured she had it for over 5 years although, it was all covered in brown slime as well as green algae. Before putting it in my tank I have scraped it all of. Now I'm getting little air bubbles on the rock right after the lights go of does that mean I will probably get the algae bloom? One more thing I have a yellow gorgonian and I noticed a kind of white film on it and now I noticed tiny little bubbles on it what kind of algae is it? Is there a white one?
