72 bow floating in there... it won't sink... it's not leaking tannins but I did soak it in a 5 gallon bucket for a few hours at least... it's floating in my 72 and has been for more then a day now... will it eventually sink? do I HAVE to weigh it down? I already attached java fern it to so I would rather not boil it if there is another way possible I will wait longer if it takes that because the java fern will get some really good light floating with the drift wood at the top of the tank. quicker growth with dry fertz and c02 injection. + flourish for trace and occasional flourish iron w/ flourite.
