I was wondering how long anyone has had their tank water tinted yellow because of driftwood? I have 3 medium- Large pieces that have been in there since the start of the tank. I added 2 small pieces as well. Did the best I could on soaking and boiling the driftwood but the water remains yellowish after almost 3 months. I am consistently doing 40-50 percent water changes and even did around 65 percent. The tank is a 240 gallon so the tank slowly turns yellow 3 days after the water change. Any thoughts of knowledge are always appreciated. Thanks
