Thanks FireWater. I tried to match the hold tank ph/alk to the main tank's (8.3 and 5 meq/L). The dipping tubs and rinsing buckets were close, but a little lower (8.1 and 4meq/L). Pretty much a lost cause at this point on most of the corals. The only thing I've been able to save so far are the blue tort and german blue digi.
For some reason the opening quote to the Six Million Dollar Man keeps running through my head:
"Gentlemen, we can rebuild him. We have the technology. We have the capability to build the world's first bionic man....better, stronger, faster"
