Jim, I really love this all natural setup (my woods has bogs and creeks all over). Do you do water changes with fresh bog water or just top up the evaporation with R/O or let the level rose and fall with rain...?
Also, have you noticed any critters in the water? I assume there has to be some aquatic things helping feed the plants if the water and muck comes from the bog.
Any form of circulation like an air stone or mini pump?
Sorry I just had to ask it all at once! LOL
