My copper band butterfly obv died last night and i cant find his body anywhere, i do have a large clean up crew and i am assuming that they did there job but i don't understand why my ammonia is showing if the body was eaten. its a 75 gallon established reef tank and the corals and fish all look fine. i don't know what i should do. i am getting sick of test kits and refractometers i think they are all inaccurate and my patience is totally tested in this hobby right now because apparently my reef is at 1020 as well!! yet everything looks normal. makes absolutely no sense. sorry for the venting.
