Slim Filter Bio-Carb replacement cartridge fits all 3 Slim Filter Models. Ideal for tropical fish, it combines activated carbon and Ceramitek in 1 cartridge for a healthy aquarium. The activated carbon effectively removes pollutants and odours, while the Ceramitek, a highly porous ceramic biological filter medium optimizes biological filtration. The easy to use disposable cartridge should be replaced every two weeks. (Never replace all filter cartridges at the same time in order to ensure constant presence of beneficial bacteria.)
I received the tank and accessories for Christmas and have been unable to find the filters at any of the local pet stores. Trying to get by with filters that really did not work until I found your website. Thanks.
Even with Freight from USA to Canada, it cost my less than my local pet store

These are great little cartridges. They're easy to replace, and work as advertised.
Easy filters by Patrick from Eldridge IA01/31/2013
these filters to a good job of keep the toxins out and letting bio filters grow on them. if you change one filter a week the biofilter will always be there too. They say change every 2 -4 weeks, I always do 4 weeks, but I've fogotten and gone 6 and they're fine, fish don't get sick or anything.
