Disgusting brown goo
			 
			 
			
		
		
		
		Hi, 
 
Its hard to say if it is dino or diatoms.  Both are slimy and both form jelly mats, but I through dinos where brown or red and diatoms were brown or gold.  Really doesn't matter.... 
 
Christy, is there anything unusual that we should know about your tank ?  Are your snails all dead ?  Did something recently die in your tank ? 
 
BTW...is that bubble algae or calerpa in the picture ?
