The bucket of salt may have gotten some moisture in it or maybe it was just not mixed well in the bucket and it settled in layers. :-(
I use I/O reef crystals mostly and haven't had any issue with white floaters or with mixing. Your salt should be totally dissolved by now, after 26 hours.....

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
