Tony, if this was happening to me, I would switch to IO. If the Kent measures fine for alk, ca, pH, etc., don't worry about it.

Tony, it's happened to me a number of times over the years, and I just ignore it. I find that it dissolves within the next few batches of new salt water.

I found it only does it when it is super heated.. The heater I was using was broken and it would take the temp over 90 and then it would start to coat things.. but now .. no problems.

Tony, the way I mixed the salt was, put my salt in a 10 gallon tank, top off with water, plug in the heater and the power head, 24-48 hrs later I'd do my water change. I didn't wait because things weren't dissolving I just like to let it sit with the power head etc for a day or so.

Good luck, btw, Kent salt will still be available but in the near future it will be made by Oceanic instead of IO. Oceanic salt will be available probably next week at my LFS. I'll pick up a bag and see how it works.
