pavona AKA green bubble algae. You will have a battle here. Best bet is to reduce or turn off white lighting and add 2-3 female Emerald crabs and even a foxface rabbitfish

Awesome yes I will do that, my corals has spread nicely as to have another tank crash where I lost everything , I had at one point a copper fish to help with apstasia but find that the fish did little to nothing to reduce the population, how much time of the white light should I reduce? I don’t want to deprive of light all corals
