Hammer coral was all shrunk up, looked like it was just a skeleton its so sucked in. Tested water, everything is good except ammonia was around 1.0ppm. Amquel got it down to 0 by this morning. ammonia 1.0ppm nitrate-0 nitrite-0 ph-8.2 phosphate-0 cal-above 500 kh around 6 specifit gravity 1.026 temp 78 and i have 2 dwarf angels, flame and coral beauty so maybe they nipped it but i don't think so. so would the 1ppm of ammonia cause it to close up?
