The manual recommends Charcoal or Zeolite. I've been using Zeolite rocks in quart size mesh bags which you can find on Amazon. You can "recharge" the Zeolite by soaking in salt water and leaving in the sun. Both help absorb impurities such as ammonia, not sure how effective they are but can't hurt.
