I recently tried to do a Diana Walstad method tank, so far seems to be doing fine but the water is dark brown, like strong coffee, I used a cheap topsoil from Home Depot called EarthGro, I believe other people have used it (http://thegab.org/Plants/step-by-step-setting-up-a-walstad-type-natural-planted-tank.html) and capped it off with sea carib eco-complete substrate. so far ammonia 0, nitrites 0 and traces of nitrates

Hi I'm new here but I have a few things to say about purigen. It will clear your water quickly of tannins(if you are running a filter) but I found that the tannins from my mopani wood stained the purigen so I couldn't tell when it was exhausted. Water changes, an extra sponge and carbon from time to time is working for me. Seven months in and I still get tea water every so often.
