Hi all,
cheers Darrel
It doesn't have to be Duckweed (Lemna minor), any floating plant will do, it just has to have access to atmospheric CO2. My "Duckweed" of choice is now <"Amazon Frogbit"> (Limnobium laevigatum), which has a <"number of advantages"> over other floating plants.plus with your suggestion on the duckweed what would it benefit as I understand it will as shade add shade from the light and take harmful nurturance out of the tank to replace with good nurturance.
cheers Darrel
