The Vortex Innerspace Diatom Filters are still basically the same. Plastic jar now instead of the glass one mine has. I sure do miss the old Dynaflow filters. Had a model that was self priming too boot. But they were power hogs compared to today's stuff.
Thinking back, the old DynaFlows had no means for biological filtration IIRC. I only recall the floss cartridge that slid-in at an angle before the outlet.
Back in those days, I ran an UGF and the dynaflow on my 20L. Knew nothing about a proper nitrogen cycle or water changes either. Ugh..

The cartridges were a later addition. I believe you were supposed to pack the filter with floss and carbon, when it first came out. That would allow you to pack some biological media in the mix and reuse it.

Cool pic! That looks like an early one for sure. Mine had the fake woodgrain top if I remember, and the filter cartridge slid-in diagonally, just before the outflow, leaving a ton of open space towards the impeller side. Well, wasted space for me, because I didn't know any better at the time.
This was my first filter (or one just like it) in a 10 gallon metaframe with a slate bottom. The whole filter was clear plastic back then (1968) and I put floss and charcoal in it.
