The nice thing with those old Dynaflo filters is you can pack them with anything you want. No such thing as a filter cartridge back then. But today's filters are so much more energy efficient than those things are.

The Dyanflo 150 (The all green ones) originally used just packed media of your choice. When a bunch of other filters started to come out with cartridges, Metaframe make a cartridge that slid in at a 45 degree angle.True. When I first got into fish keeping, the Dyna Flo's used a cartridge by then, but I suppose you could have loaded them with floss, sponge, etc.. This would have been around 1980. I do recall seeing the older style ones in use at LFS though.
