I have never had a acrylic tank but I found a 240 for a very cheap price. Needs polished up and stuff. My question is the openings in the top are very small. I want to put some large driftwood in it. I figure I can cut the top of the tank off , get it all cleaned up , put my stuff in it, then reattach the top. So is it better to cut the top off at the top leaving a rim around the top or to cut around the sides of the tank? Also can I just reattach the piece I cut off or do I need a new sheet. Sorry if its a dumb question and thanks for any help. Here are pics of the tank.
