Classic Aquarium Equipment

I just found another article about the Aquaclear 610. The 610 had a sort of impeller housing where there was a "peanut" that extended down of the bottom of the filter and into a motor. An impeller was dropped into that plastic extension and spun. The only problem with this design was that, if the motor overheated, the plastic would melt and destroy the motor AND cause a leak.
 
The brown ones were Aquaclear 610's and the motors are pretty close in design to how they are now. In fact, the item number for the Aquaclear 50 is still A610.

The Green filter in the thread is a Dynaflow.

Original Marineland Magnum 200/330 models, original Penguins, and Dynaflows have two rotating parts. An outer magnet and fan rotor that spins and pulls along a second rotor inside the filter housing. Which you are correct is pretty inefficient.
 
You are correct. When Aquaclear changed to the first revision they eliminated that extension and sealed the motor to the housing (a la Whisper).
 
They were the first to manufacture the modern style HOB filter. You can look up the old Willinger bro's patents to find more.

US Patent #4,512,885, 4,861,468, etc...
 
Memories, memories! How about the good old Tetra or Penplax under gravel filters! I did a search and they are still around. I remember when they were state of the art and the bee's knees in the hobby. Hell, I still have a couple of panels running in my old school 40 long just because I've been too lazy to tear it all down and go with a sand substrate. Still plugging along, in a tank I've had going in one incarnation or another for over 30 years.
 
I used to have a dynaflow 150. I don't think it was that inefficient and the best thing since the motor was outside the box, almost no chance of a leak since there were no O-rings. I was a teenager when my Dad bought it for me. And at that time there was a plastic frame you could buy and make your own cartridges by cutting to fit your choice of media.

There was a small pet store on 5th Street in Norht Philadelphia that had a LOT of old equipment new in box. I remember the gentleman had a kit made by Metaframe to allow you to use your Dynaflow 150 as a diatom filter. I used to work at the biology department at Temple Universiy and we had a LOT of Dynaflow 150/ lying around all over the place. I always wanted to ask my boss if I could have one (this was the 90s. The 150 was long discontinued) and go buy that kit.

Instead I went out and bought a Second Nature Diatomagic.
