Tank transfer didn't go well

I still don't see why the transfer would have really caused these kind of problem. Obviously it did but it still doesn't make sense to me. There really were not many changes. The corals were out of the old tank and in the new tank within 30 minutes.

I guess it must have to do with the water change, new tank having something bad in it (I did clean it though with RO water) or just my luck

FWIW, I always mix my salt a day before or less and have never had any problems over the past 6 years.

I hear ya, it's not always an ideal situation when doing a big job like that. Sounds like your salt dissolves quickly. All we can do is try and learn something from it to save our asses next time. Hopefully the death will stop soon and you can enjoy your new tank!
