Actually that's about par, it was just an inconvenience to take time off work to go to a place that could refill it (because any such place will only be open when I'm supposed to be at work myself, with the only exception that they open later than when I start, and close earlier than when I finish .... what is UP with that anyhow!!!) and then to have to do it twice (once to drop off, once to pickup).

A tank exchange program would be better.

Ok in the end it wasn't the only reason, I always had issues with the designs of the ones I was using, I also had issues maintaining steady slow flow through those things (would be easier nowadays with peristaltic pumps and controllers so a bit of a moot point perhaps) and plus there was the whole "I want to reduce my CO2 footprint because I *care* blah blah blah".

Like I said I am sort of considering going to back to a reactor. As soon as a few other projects are off the to-do list I was thinking of building myself a new one. Been far too long since I did any acrylic fabrication for this hobby. Might be time to revisit that.

Oh I totally forgot that the other reason was I wanted to devote my CO2 resources towards my planted FW tank. Although I kind of haven't refilled the tank yet from when it last went empty about 12 months ago.
