I'm sorry i didnt know it was a acrylic, it think that eitherway you go will work just as well, and since its acrylic you can get the clear tubeing and fues it either wat you go. if you drill the side you can put on a elbow and it would work the same as having a bottom drilled tank interms or adjusability.
For now, let's just call it 'the pipe on the rag'.
