I am using Duetto Internal Filter (DJ50) as my CO2 diffuser. Have a look at
it at

Ok Ive started a new thread

Leigh Stated earlier
"I am considering switching to some kind of reactor, or injecting directly
into the filter intake, in hopes of lowering the maintenance required.
You
do have to rinse the Eheim diffusor's ceramic disk every week or two, to
keep the CO2 bubble size small."

Is the eheim made for this, or are you just putting the air tube into the
intake line in the tank?

I have a Magnum 350, would the gas just create a large air pocket in the
canister, or would it be disolved? Anyone tried this?

Thanks!
