IO salt low alk?

[adw]

I just mixed up some water with some instant ocean salt and the alk is really low. Has anyone else found this?

I use IO and have always had a consistent normal level as far a alk. The calcium is always low though about 350with a fresh batch.

I have always used IO, Never had any issues with it. I will be keeping an eye on it though.
