there are these little light colored pin size dots arranged in what appears to be some sort of pattern in small splotches here and there. they are light colored, and look almost like air bubbles that have stuck to the glass. they are not "slimy" per say, it's kinda a rough texture and took some fingernail action to remove. is this coralline algae, or cyano, or somekind of weird alien egg cluster thingie thats gonna absorb through my skin and take over my brain.....
