Hi, starting last week coraline algae starting dying in my 4 month old tank which was covered in it before. I test alk daily as well as my other parameters and everything has remained stable. It seems to be dying like there is a bacterial infection but all my acropora are still doing fine and encrusting. I will attach some photos as it has slowly spread and dyed throughout my tank. My bare bottom is like a mirror now where as last month you couldn't even see it. let me know what you guys think! Thanks
