Fuzzy salt creep?

[ParsedOut]

My salt creep is super fuzzy in my new fully enclosed canopy. Almost looks like mold. Any suggestions or opinions on what this is?

Thank you both, is this a common thing? Tried searching before posting and all I got was mild in the tank, not outside of it. How do I avoid it going forward?

More air flow to keep moisture from building up. That’s how I solved mine.
