thanks its actually 6 pieces of wood , was the only way i could get the affect i wanted
the plants on the wood are , java fern , narrow leaf java fern , congo fern ,java moss and a small bit of anubias.
yup i use flourish now
so every Thursday i do a 35-40% water change and then add two and a half caps of flourish
so 12.5mls , approx. seems to be going well
still no co2 low tech it will stay
