Re: [APD] Re:CO2 Reactor Questions -- or - Scratching the

The canister method works really good as a co2
reactor.  I'm running 2 DIY bottles on my Magnum
350(no biowheels).  The rate is low enough that the
co2 disolves before it develops any space or water
noise.  The advantage of the 350 is the impeller being
on the bottom.  No worries about cativation or filter
stopping.  I'm running 2 layers of generic floss and
the co2 is forced to disolve before it can be sent out
the system.  If any bubbles were to catch on anything
they would stay until disolved.  It's disolved about
an 1" of regular air in less than 8 hours.
