So I've got a 4-5 month old waterbox frag 105 that is getting this white film with little white dots growing on the glass. There has been this white film at the water line since starting but now it's growing into the rest of the glass. Scrapes off very easily and looks like snails are at least going through it, if not eating it. Tank was started with dry rock, live sand, rock that was kept in a trash can after cycling from a tank that got a leak, and well established rock from my other tank. Parameters are all normal (I've been doing this for a bit) all corals and fish are looking fine.
