			 I bought 2 big chunks of reef bones yesterday and have decided I want to make come caves and holes in them for my fish before I cycle them. 
		
	
		
		
		
		
		
	
		
		
	
	
	I will use a masonary bit for the smaller holes, but I also have a 3 inch metal hole saw. Would that be able to punch through the reef bones? They're fairly porus, so I think it should work. Any advice?  |
