Hi everyone -This is my first time posting here.I wanted to get some clarification regarding coral growth and nutrition. I heard some people saying that they have good growth with just good lighting and no supplements but I don't understand how corals, especially LPS with a lot more soft tissue mass, can survive long term only on good lighting. I understand that they get their energy source from the zooxanthellae but what about the raw building blocks for their soft tissue? Ca and Mg are of course supplemented but I can't see how tissue can grow without additives. The ocean has tons of micro organisms that they probably feed on so I imagine we need to create the same nutritious environment in our small piece of the ocean?Thanks everyone for their input!View attachment 2015
