i havent done what i wanted. disater. bucket slipped and water hit the sand causing it to move and release bit of soil and water was crystal clear before the accident. i tested the water for ammonia, nothing. water quality is unscathed
as in a walstad method tank, but just with a filter also not being fed up with adding different ferts and the soil will last up to a decade, basically lasting ages. for my sword, vallis and future crypts.
