OK I have been told that this fish should have some drift wood. I have a piece of drift wood that is probably over 4 years old maybe more. It has been out of the tank for a long time. Its the kind that stands straight up and down with a piece of slate as its base. The problem is I used to have it in a 20g and it was lowering my PH. I took it out never had the problem again. Would it be ok to put in my 55 for my pleco? Is it too old? Will it give me a PH problem again? Is there something I should treat it with? Right now it just sits on a shelf all dried out.
