Is there anyone that can help me with my coral tank? Everything looks like there dying off. I have lost two plate corals two xenias and the rest have either stoped opening or have swelled up way to far. Nitrite 0.10 aminoa 0.00 temp 79.deg salt 10.22 nitrate 0.00. I have had it runing now for 5 years and i am at my wits end. Had one fish a clown it died last night, pulled him out with the rest of the dead corals. have only 15 crabs blue legged, 5 turbo snails, they havent moved all day,half in their shells. Im completely confused on the whole matter. Any help out there.
