i feed tree/four times a week phyto and zoo with cyclop-ezze and vitamins ultramin s and grotech (M). Parameters are (Kh, Ca, Mg, NO3, PO4): 8, 420, 1290, 2, undetectable.
I'd like to know if it's possible a gorgonian keeps its polyps closed for days or for the other hand, it should have already opened its polyps...and when i say closed, i mean closed, closed (it seems simply as branches)
