One of my Zoa frags is shrinking and not opening (opens and closes). I thought the Par maybe was too high, so I placed it under a ledge, but it still isn’t doing well. Wonder what I should try and where to move it. (FYI - I’m trying to get better as a reefer and willing to take a chance and move it to learn, but where it is isn’t working). The Acan looking like it is closing and on it’s last leg. I think it is getting the highest par of all my acan’s, but all the others are doing well. I have redsea led90’s at 45% blue. My guess is my par is around 150. Any input would be great. Thanks
