Ok, I have been to the pet store asking almost every associate I seen for their opinion about what kind of minereals or elements I need for coral to grow and flourish. Each one of them seem to have their own different story. Due to my mistake and diaster recenlty, I am now on a low budget and want to be cost effective because these minereals or elments for corals is quite expensive. I know for a fact that corals need cacluim and food which I already bought some, but I don't know if that will be enough from my coral to grow and expand. All I have is just zoanthids, yellow ployps, and some star ployps, but plan to add more in the future. If somebody could point out a bottle that contain the majority of the essentail element neccessary for coral growth(if any), I would grealty appreciate it.
