So recently my Duncan has been retreating and hiding except when the polyps barely come out at night. My hammer and frogspawn have also been barely open and seem mini compared to normal. My once thriving acan has its skeleton showing on the top and looks terrible but little feeder tenticles come out at night after I dipped that (plus the duncan) with ME coral dip 4x solution. Any clue what's wrong? The water chemistry is fine. It thought it was because my water change temp was off or the alk swung too much one day but its persistent and nothing about the chemistry is off. I dose reef energy everyday and nothing has change about the tank since it started except for using a large amount of eco balance by dr Tim's at once. No others except the corals mentioned are having this problem Any clue what's wrong?
