Cool, big peices are what I'm looking for, depending on. Salinity was very high. Do you have a refractometer? Also, if you have livestock in there, I think you want to slowly acclimate, but it sounds like you've done it already, and things are leveling out. Water is a little warm, ideal reef temp is 79F from what I've read, but I don't believe 81 is out of the ballpark high. From what I understand, your ammonia spike could mean a second cycle, or your tank never finished cyling to start with. There's not a lot of information on your cycle, you just stated that you thought you were ready. How long have you had this tank running, and how did you start your cycle? What are you levels for high range PH, ammonia, and nitrates?
Also, take everything I say with a grain of salt, I'm learning as I go along, so I don't claim to have all the right answers, just trying to help you get yours!
