Remove tannins - Purigen?

Is there a more effective way to remove tannins than purigen? I'm using 2x portion of what is recommended for a 55 gallon and 1 week in, the tannins are clouding the water already again. I boiled the driftwood except one huge piece. Not sure what to do besides changing it every week.

Hi TheLordOfTheFish,

I do not treat Purigen as a 'one time' treatment. When I have new driftwood I run Purigen as one of the mediam in my filter 24/7 for several months until the amount of tannins the wood is putting out diminishes. I like Malaysian Driftwood and it can but out tannins for a year or more. At first I have to 'recharge' the Purigen every month (or less) but eventually I can go several months between recharges.
