My 100g tank was perfectly fine yesterday and when I got home today all my sps corals were bleached white and my lps corals were all closed up. I did a water change right away and swapped out the carbon but everything seems to be getting worse by the hour. All of my fish are alive but the tank is super cloudy. I’ve had this system for over 3 years and I don’t know what it could be. I do not have any test kits at the moment but my sg and temp are fine. I had a short spine urchin that died too but my other inverts seem ok. Most of my soft corals are so doing alright but at this point all my lps corals are slowly dying. I don’t know what else I can do by tonight. Someone please help!
