metalic sand

[Scavenger]

Sorry I shouldn't have made a joke while you are undergoing what could be a nasty problem.

Anyway, I don't have any suggestions except maybe if you can still get hold of the sand provider and see if he has any information for you. ie how long was it in his tank and did he have significant die off ect.

Hang tight, I'm sure one of the senior reefers here should have an idea for you soon.
