I ended up buying a filter bag and some loose carbon media to help remove/absorb any excess tannins that may leach out over time. I will be using it with the regular filtration I have going. As a suggestion, you could go that route before you get your tank cycled so you can put your driftwood in. I've read that the carbon does absorb the tannins (which only lowers the pH of your water), but it will stop absorbing tannins eventually, so change it out once in a while for good measure. You could also play the "I win" game this way and succeed
I'm still waiting to throw mine in the tank possibly tomorrow. I have a 10g in mid-cycle. I figured it would be good to get it in there asap just in case it affects the cycling. Also, I hope this method gets rid of the small oil-like sheen spots on the top of the water as well. I'm not too sure if those are hazardous although I've read that they aren't in a different forum.
