All plecs rasp on wood, as it aids in their digestion. I have three ancistrus in my 55 and though they spend a lot of time on the driftwood I am in no danger of it going away, LOL!
i dont think plecos have teeth so the driftwood wont go away anytime soon, compared to us chewing on a piece of wood :/. and the poop is probally mainly from eating algae. since thats their main sorce of food
