I have lots of old fish related equipment. Some of the stuff is over 30 years old. Fish tanks (with slate bottoms), heaters, lights (Metaframe), filters (like old Dynaflos, Supreme AquaKing), Lustar plastic breeding traps. etc. . Some of the stuff I still use. Other stuff just sits in boxes. Longest running filter is an old AquaClear 200 (amber in color), been running continuously for over 25 years and still going. Metaframe light with incandescent sockets from the 60's still working. A lot of the stuff they make nowadays is junk. They don't make em like that anymore.
