Hey all. I might be jumping the gun a little but I am unsure. I currently have a 30 gallon reef tank up it is new and so am I to the reef world. I have this dark purplish/ black growing on my live rock with what looks to be silver bubbles on it. I currently do not have pictures because my lights are off. Also last time i tried to load pictures on here it didnt work,,, So my question is... Is this part of the coraline and the die off of the nitro cycle or is this something i should be worried about and jump right on...? I feed once a day and my lights are on for 10 hours a day. I also do 20% water changes every week. Please help me let me know if i can calm down or if I should be worried any and all help would be appreciated sorry about the no pictures I will take some tommorow and try to up load them
