Reef Crystal IO salt

Personally I am thinking it can be that buckets of salt can have some variance, but also the test kit may not be accurate.

Try another test kit if you have one, or have someone you can borrow another brand of testing.

Did you give the salt in the bucket a good mixing before you mixed up your batch of salt water? This can greatly help to get the parameters closer to normal as some settling of individual minerals always occurs during transport.
