So I did a bit of searching and I have not been able to answer this question yet. If I was going to try and get my own wood for a tank, are there types of wood I should not use? I would assume any type of pine or wood with a lot of sap would be bad. What else? Do I need to look for anything special? Also, once I find this wood how should I treat or prepare it? I have a hard time justifying buying wood if I can find it for free. How ever, if there is a reason to use specific or rare types of wood then I will definitely just purchase it. Thanks for your help, and education.
