FOR FREE or trade for frag - 6" cast acrylic tube 1/4" thick
 

I have a 4.5" long cast acrylic tube that has 1/4" thick walls. Very strong and was very expensive when I bought it. But my DIY aquarium equipment days are over and I rather give this to someone who can use it than to throw it away.
if you gotta a frag to trade, i would also be happy to exchange.
