Problems with Kent salt

[christyf5]

I bought a couple buckets just before Christmas. Cracked the first one open pretty much right away. Everything was fine with it. I just opened the second one weekend before last. When I moved my tank I made up about 48gal of new water with it. Didn't really notice as I was a bit frazzled but after scoping out the tank in its new digs after it was all put together, the water looked a bit cloudy, not quite clear. I figured it was just a byproduct of the move. Then last weekend I did my regular 15g water change and noticed that I couldn't see into the bottom of the bucket after mixing the salt. Usually it clears up within about 5 mins. This stuff still wasn't clear after an hour. I tested all the params I could test for and everything came out about normal (I thought). Alk=12 Ca=450 hmm now that I think of it I couldn't find my mg test kit (probably still packed). I did the water change anyway as it looked fine and has had no adverse effects on my tank. There was a fair bit of color loss which I had attributed to the move as things are perking up again. Anyway, I bought a bucket of IO. Sure enough its not just me, it mixes up right quick.

So I was just wondering, if anyone can remember that far back if they had any issues with kent salt in january or so. It was weird as I had bought two buckets, one was fine the other not so much. I didn't check lot numbers or anything.
