Sorry to hear about you losses. I'm new to this forum and to the saltwater tank hobby but I had also had a similar problem with fish continually dying. I had my LFS
check the water levels and everything checked out. Except they were not checking the water hardness. My dKH
was low causing continuous death to newly acclimated fish (most would last a week or 2). Since adding a dKH
buffer I've had no mysterious deaths. Of course now I'm dealing with an ich/parasite problem
Hope all works out for you!
