Just made a really nice crack in my refugium

I shoulda known, it was 8:30pm and I was all like, oh I'll just change out this leaky fitting and then go read my book for awhile. Well its now 10:30 and I just finally finished. Thank god people are constantly dropping tanks off here and I had a spare.
So do cracked tanks go to the recycle depot or the dump or what?
