That's just my point, the 301 didn't provide enough turbulence. I have an
empty gravel vac, suction cup holding the hose in teh middle of the vac
tube, a 2" sponge piece in the bottom and the Magnum providing water flow.
The turbulence is so good I don't need anything in the tube to create more.



Since I'm getting ALMOST enough CO2 diffused with just the cup method, I'm
hoping I can get by with the 201. I got it cheap because the package was
opened, and it came with 301 instructions. I will give it a try. I'm going
to try using biomax rings in a tube. Might as well get some filtering action
while we're at it right? It would be good to have a backup should my whisper
power filter fail. Sometimes I'm not home for a weekend or something.
