i found pieces of wood out side and want to put them in my tank for my corn to climb on. i removed the bark and sanded them smooth, put them in a bucket of 1:10 ratio of bleech and water for an hour, then in a bucket of pure water for about 8 hours, then them let them dry, then put them in the oven at 350 degrees for about 10 minutes. i just want to make sure i'm not harming my corn.
