How To Replace Fluval U Series Cartridges
Do not replace all filtration cartridges at the same time. Alternate filter cartridge changes so that some older cartridges remain in use. This ensures the re-seeding of beneficial bacteria, so that colonies discarded with older cartridges will be replaced by vigorous new ones. To enhance bacterial action, pour a dose of Nutrafin Cycle Biological Aquarium Supplement onto your filter cartridges each time you change the media.
