Coral help

i'm introducing corals into my tank and having difficulty keeping them alive. the water has been checked for everything and its fine. i have 4 fish in the tank, good lighting, powerheads on each side, adn 2 filter systems, and i change the water on a regular basis. this is a 50 gallon tank, any advice would be great!
