I have a med. to large piece of driftwood on slate with 3 holes in it about 2 1/2" in dia. $15.00, half doz. sheels ping pong ball to baseball size $9.00 for all, 350 magnum filter complete working $35.00, and lots of what I look at as junk as I have bare bottom tanks( Discus and rams )and don't have a use for them at this time. I live in St. Paul, Mn. and am always willing to deal.
