So no matter what I do most of my corals are slowly dying all except my 2 hammer corals, it’s my softies like clove polyps and purple anthelia that are dying first my purple anthelia was the first to go and the rest are still hanging on, my tank parameters are, ammonia 0, nitrates 5-10 , ph 8.2, alk 190 ppm , phosphate 00.25, calcium 420
