How to kill anything
No, this will not tell you how to kill anythings, though if done wrong I might kill something I did not want to, or add something which kills everything else in my tank, so I will ask.
I found some wood near a stream when I was hiking two weeks agao. I love the style and thought it would look great in the tank. Took it home and put in a bucket of water and ofcourse iit floated as it was sunbaked dry. Now after about 2 weeks of soaking and changing the water a few times it has sunk, though does have a little sliminess to the wood now.
What I was wondering is how can I make sure there is nothing in it that will harm my tank (live organizisms etc). Can't boil it due to the shape and size, so what is the other option. Just soaking in water can't work, right? Do I add salt? What is the process, please help,..
