Useful Information

Changing the Bio-Bag®: When water flows excessively from the Wonder Tube Chamber into the aquarium, it is time to change the Bio-Bag®. The Bio-Bag® should be changed once per month to prevent backflow and avoid filtration problems resulting from a clogged Bio-Bag®.

  • Remove Bio-Bag® from filter, allowing excess water to drain into filter box.
  • Remove clip from frame, fold up frame flap, and remove floss bag from frame. Place new floss bag over frame.
  • Add one packet of Ultra-activated® carbon.
  • Fold flaps of Aerobic Frame® over filter bag and replace clip.
  • Rinse Bio-Bag®, insert into filter, replace filter cover.
