Extremely High Alk In Instant Ocean Salt

The next bucket I opened went back to the 10-11 that I was expecting from IO. I've been slowing bringing my Alk back up in my tank. Now I always check every new batch and I roll every bucket (have for years).

I had the same issue. Bought my bucket from a local vendor on Boxing day of 2011. Sad to say it killed my tank. Alk was low, Mag and Calc were through the roof, who knows what else was wrong. Took me forever to figure out what wiped out ALL fish and inverts in my tank... I did notice the consistency was different than my previous buckets. Usually it's somewhat coarse, like table salt. This time it was much finer, like baking sugar almost.

I know that a lot of people have success with IO (and I did for 2 years before that too), but I've switched brands now.
