Ok so this is the third time this has happened. All my corals are slowly dying off and shriveling up. I've address gfo, tds, parameters, temp, feeding habits, detritus, flow, lighting, and frequent water changes all in the time span of about six months. I've taken corals to a friends and had them growing and heathy in his tank. Did a 98% water change and cleaned everything before bringing them back over. They where fine and growing for about a month then started dying and shriveling up again. I have run out of ideas on what could be wrong with my tank. Anyone have an idea as to what might be going on here? Need help bad!
