Does anyone use those vitamins in their SW tanks? I am asking so I know if I need to put any of that sort of stuff in mine. I dont want to do it if it is unneccessary. Also how long does it take for stuff to open up? I have 2 Kenya Trees (which are open but not fully), a small bunch of Star Polyps (which are not ope at all) and a rock of Blue Mushrooms (only a few of the at least 12 have opened) Or is there something that I am not doing? Please help!?
