Warning! Potential Problem with Kent Salt.

[untamed]

That is a huge problem for Kent. That is one ugly discussion. I have used nothing but Kent salt for 13 years. I guess I got lucky because I've only been using the 50 gallon bags and it didn't hit me. I've been very careless about measuring the freshly mixed SW.

I think the expensive question I'm asking is..."How could an error that significant happen?...and what does that mean for the less significant (but also important) elements of the salt?" It suggests to me that there is very poor quality control going on in their production, and that is enough to scare me away.

There is a huge level of trust that aquarists place in their salt manufacturer. I had assumed that the salt I was using was subject to testing such that something like this just could not happen. I was incorrect.
