I just bought some driftwood and was wondering how long it would take for it to not taint my aquarium with its coloration ( i understand that the color is actually good for the ph quality of the water ). I have boiled the wood about 10x over a period of 2 days and have noticed that its taking longer for the color to seep out of the wood and in less color intensity each time. Do i have to wait for the water to be absolutely clear in the pot in order to be secure even after an immense boiling session ? I let the wood sit in the pot overnight submerged in water and the next morning all was clear, is this a sign that it is ready ?
