So today I added some more live rock to my new tank that is still cycling....I know this may cause the nitrites and ammonia to spike even more. My question is that this morning, I noticed more of my coral is starting to be covered by a few spots of bright green algea...but mostly, a very thin coat of dark brown/green algea/slime. Some of this slime is also on the parts of my live sand. When I started putting in some of the live rock I just bought, i noticed tiny bubble coming up from the sand....I realized there are little bubbles forming on top of the sand that has the brown algea....what's going on...is this all part of the cycling process? The sand used to look so pure....and well pretty???
