So i have some acro's that i have kept low in my tank and they are popping with color. Why should i move them up in the tank. i ask this cause when i move them they tend to fade or do not do so well.
Moving them up or increasing the light has to be done gradually to acclimate them to more light slowly. Some corals will reward u with better color and growth with higher light and some not. It's about experimenting and seeing what u get.
