Hello. Good ideas. But some body know what exact remove from water willow ?
If this method real work, i will try make live water conditioner(no cash for RO unit) in 2ft aquarium at my window and then regulary add water from 2ft to my 100gal tank.
What do You think Guys ?

If some body can, please post Yours results after willow in clean water for some time(not in aquarium with stock) - what's water chemistry, how they change, ph, kh, gh, tds, e.g. ?
