Bad batch of IO salt still circulating?

[Buccaneer]

It is not the tank reading that was off in my case as it seems that the tank equalized the higher alk all by itself after awhile

but the high alk reading ( 3 to 6 times normal ) when it was just mixed and subsequently introduced to the tank ... the fish/inverts that came into direct contact with the new salt water are the ones that died

my question is whether he has tested a fresh batch of water for alk and what that reading was.

if it turns out that it is not the alk then I would send a sample of the salt to Randy Holmes Farley at RC Chemistry forum for analysis.
