Keep your aquarium's water clean and healthy with Top Fin RF-S Small Retreat Filter Cartridges. These cartridges are easily replaceable, and feature coconut shell activated carbon, which serves to absorb undesirable odors, pigments and chlorine. Only at PetSmart.


  • Coconut shell activated carbon to help absorb undesirable odors, pigments and chlorine
  • 6 month supply

    Includes: 6 Count
    Intended For: Aquariums

    Product Dimensions: 8.1 in L x 1.9 in W (20.5 x 4.8 cm)
    Advice for Use: To help maintain a healthy aquarium, change filter cartridge every 3-4 weeks, or if water flow becomes obstructed. Remove cartridge when medicating water as carbon will absorb medications. Change out 10% of the water weekly or 25% monthly. Use a water conditioner (sold separately) every time you add fresh tap water to your aquarium.

    Step 1: Remove used cartridge.
    Step 2: Rinse new cartridge under cool water to remove dust.
    Step 3: After rinsing, insert cartridge into filter chamber. Make sure cartridge fits completely into filter chamber.

    Caution: Never use soap, detergents, or cleaning agents while cleaning the aquarium or equipment as they can harm your fish. This is not a toy. Keep out of reach of children.
