just a note, i did try to use arcylic to partion my 40, but what i ended up was a big junk, cut it w table saw, but realized that it was cut uneven, so i had to use the clue to try to fill it in, but no matter wat can't keep it from leaking, spent more money on clue then on the glass piece that i got to replace it. i went to bunsingwer glass and had them cut a piece of glass w the thickness of 3/8.
