I need urgent advice here. I have 1 hammer, 1 frogspawn and 2 torches. Recently I have use alot of Rowaphos and thereafter, caused 1 of my torch and 1 frogspawn to die and only left the skeleton. 1 more torch seems to be dying coz the flesh starts retreating. Although left skeleton, I'm hoping they are not dead and will rise some day. What could be wrong? Here are my water paramters: Temp: 25 to 26 degree Celsius SG: 35ppt Alkalinity: 9 dKH Calcium 400 ppm Nitrate: 10 ppm Phosphate: 0.06 Sent from Singapore Reef Club mobile app
