so sorry for your loss - that must have been horrible. Thanks for sharing as this will help so many others.The mistake that hurt the most was moving from a 90 gal to a 230
I didn’t have enough water made ,
Transferred the fish, corals. Some of the sand and within 15-20 mins I had a full bacterial bloom that I really couldn’t do anything about other than wait for water .....
I lost every coral , fish ,
The whole house smelled like death
