Im still new to the saltwater world and my tank has been running good for over 6 months no real issues but this stuff showed up over night not sure what it is. if someone could point me in the right direction on what it could be that would be really appreciated. Thanks.

Do you have any snails? These might be their mucus trails.

No I don't have any snails. Could it be like white algea?
