Yes, patience is a fairly new concept to me
.
The tank is 81g shallow (w/56 gallon sump). I didn't plan to add any more fish for a long while, so I will remove the deceased and see what happens in the next month or so.
All of the rock was cured, but the first batch definitely had some die-off between the time I bought it and added it to the tank (I added the rock in 2 batches, but it was all in for a few weeks before I added the fish).
