I don't have any issues at all dave ...but all my colors are dark......black,brown.ect. never had a clumping issue...I only mix as much as I need and that's it....for me storing salt will get moist..and that's where your clumping starts......if you don't want to mix up your own that small qt. size from bait junkies seams like a great deal........I looked for salt at cosco and sams club....found at sams 50lb bags...way to much for me..that was a while ago....
