So out of nowhere this weird crystal build-up has shown up on the outside of my tank towards the bottom, has anyone else had this problem, and if so what is it??

No big deal, clean it up....this is why it is not ok to top off always, instead of change water. Somehow those same crystals need to removed from the water, they can not be seen in the water.
