So I gave up boiling my driftwood multiple times to get rid of the tannis, so I am going to just have the tannis leech into the water. After awhile it's actually pretty cool to have. Anyways, how long before the tannis fully leeches out and the water comes clear on its own? The driftwood is not big, its probably like 6in by 6inch and 5 inch high in my 10g. Boiled it 6 times for a good 30 mins each, and soaked it 5 times over night. Still the tannis is pretty dark.
