Before anyone chimes in, NO, I have not lost my complete mind and no, it is not for my reef. Just a project I am playing with.
 
If your project is for a fresh water tank, I recommend using shot gun wadding. It's cheaper and readily availible. If it is not for the tank then I recommend I shut up.:lol2:
