removing tannins from tank
the new piece of driftwood is making the water in my tank a little too dark for my liking.yesterday i did a 50 percent water change and today its just as dark as itwas before the change..whats my options here to remove the tannins without removing the piece of driftwood? should i be doing big water changes every 1 day or 2 days? idont know how often is safe for my fish?? and how much water should i do in each change?
