[APD] RE: Rift lake refugium

[James H <spreerider at gmail_com>]

to avoid root rot you can add a bubble stone and small pump under the
plant so air bubbles up around the roots, this will take away some of
your co2 if your dosing but will prevent the roots from rotting, in
hydroponic growing you put a bubbler in the main tank to keep the
water oxygenated, and recently people have been dosing o2 in the water
just as we dose c02.
