Hi! I'm kinda new to the hobby and just purchased a lobo brain coral from my lfs. I have had my tank up and running for almost a year and a half now. My tank consist of sps as well as lps. I'm starting to see white specs from it and it's not the tentacles. Should I be concerned? Also can anyone give me some care tips. I tried to upload a picture from my phone but I won't let me.
