Slim Filter Bio-Clear replacement cartridge fits all 3 Slim Filter Models. Ideal for goldfish, it combines zeolite and Ceramitek in 1 cartridge for a healthy aquarium. The zeolite effectively adsorbs toxic ammonia and reduces stress on fish, 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.)

Great service, took next to no time at all, when I couldn't get anything at all locally. The only local place that did order it for me....it arrived the same day as my package from you. :-) I had ordered it weeks before. SO THANKS!

I can't find these filters in my town so I ordered them. The order arrived fast, good service. I will order them again.
