ok so i recently set up a 210 and was soaking a big piece of driftwood in the bath tub for a week or 2 changing the water every other day. then my mom said it looks clear so i droped the piece and a few others that i was soaking with it in the tub. and first few days clear but now it started leaching tamins or watever u call it. my question is how do i clear it up with out doing a major waterchange?

He's a keeper.........a good boy!!!
