empowered us with this mighty blow against the
Patriarchy:

Has anyone out there used one of the Carbo Plus block systems for CO2
generation?
I would like to know how well it works, and how often the carbo block
unit needs to be replaced.
I would use it on 26 show with a timer to turn off at night...
It seems much simpler than the regulator, bubble counter, etc.
Thanks

If you do get one of these units, make sure you run it for a couple of days
in a tank without fish before putting it in your aquarium. This wasn't
mentioned in the manual that came with the unit, but I did find it
somewhere else, I think at the manufacturer's website. Unfortunately I
didn't do this, and lost three fish as a result.
