:bawling: My new tank crashed on the weekend. I bought an established system recently and took 90% of the original water with me. Everything was doing great, water parameters were fine. I went camping on Saturday came home Sunday and the water was cloudy and most of the corals were dead. Checked the parms and the ammonia levels were 4ppm, they were 0ppm when I left Saturday. Changed half the water last night in hopes of saving some of the last bits of coral but this morning everything was bleached. Also lost 2 damsels and my clown. Hoping the local LFS can take my 4 tangs while I stabilize the water. Very devastating for me as I am relatively new to the hobby.
