Cover mold?

[GCS]

Opened the cover this am to find this spot. Tub is set to about 100 and runs filters twice a day. Water chem has been fine just needing adjustments for bromine each day til I get it dialed in

Is this a major concern and any special way to clean it?

I just sprayed mine with chlorine, you can pour some 10% in a spray bottle and hit the entire bottom of the cover..

Anything I can do to prevent it or is it something to even worry about

It is in a wet, warm environment, I doubt there is anything you can do to stop it.. Maybe some kind of mold spray but I would rather not use chemicals inside my spa as chlorine works.. I ran mine as a chlorine spa and splashed the top with water when I got in and out of the tub
