OK, just talked to J&Ls.

Their 24-hour test mix showed "alkalinity off the scale" too.

They have the sample of salt put aside. They said I can come pick up the bucket for testing purposes... so basically they're being good in the sense that they're giving me a free bucket of salt, albiet a defective bucket of salt.

But I guess for liability purposes, when I flat out asked them if they had defective IO salt, they said is that all they can confirm is that the salt they tested had really high alkalinity.

No other bucket from there apparently has been a problem. Even the new bucket I got from them, the same "batch", was perfect.

I'll let you know what Aquarium Systems has to say.
