You don't want salt creep. You also don't want salt
falling on your live corals, or other immobile invertebrates.

No problem, unless the salt gets your lights. As far as the salinity
is concerned: not much. The water is evaporating with every splash.
The end result is the salt buildup. Scrape it off and let it fall back
into the aquarium. Small salinity changes have little effect on the
habitat. Because of the evaporation, you'll be topping off more
frequently though.
