Hallo,
I gave up on the willow method this week. I had two kinds of willow in my tank, about 6 sticks each. After 5-10 days, roots appeared but it did not clear a bit. Then I tried a 5 day blackout (left the sticks in) and checked this morning: The water was still green! The roots on the sticks were quite impressive.
Ok, did 3 90% water changes in a row and cleaned out most of the muck. Appearently most beard algae died. Some plants started growing again during the blackout (Sagittaria, Crypts, Annubias, Echis, Hygrophilia). Limmnophilia stayed inert and my Lotus lost most of the leaves.
I dosed now NO3 to 8mg plus FE and PO. Wait and see ...
Greets,
Peter |
