Can someone please tell me what this green stuff is and if its an early stage of purple coraline or not? As soon as I started adding liquid calcium is when this started growing and my calcium level is 400..
It will depend on several things like calcium and magnesium, light cycle and probably a bunch of other things that will make it happen faster. Don't add purple up to me it is a waste, and I got some free.
I wouldn't add anything like that purple up stuff to your tank, and unless you need it I wouldn't be adding calcium either. Don't try to fix what ain't broke.
And it may never turn purple, it might be green coraline, who knows.
