[APD] carbo-plus co2 injection

[Eli Moss <mossy173 at gmail_com>]

As I understand it, this method of co2 injection is based on reacting a
block of carbon with oxygen in the water to form co2.  Wouldn't this
significantly deplete o2 levels in the water?  Also, how long would one
block be expected to last?

Incidentally, does anybody have an old regulator with solenoid that they'd
be willing to sell off?
