Purigen/activated carbon bag box for aquarium sump

This is an improvement part for Purigen or Activated Carbon bags. A common problem for fish keepers with the Purigen or Activated Carbon bags is to make sure the water flows through the bag to maximize its use. This box solves this problem. The water must come in through the bag and exits through the 1 inch (2.7cm) hole, where the water pump (intake) should be installed. For pumps with wider intakes I can customize if requested. Hope you like it.
BUT BE WARY! Careful with the filament you use u
