    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.

    Advice for Use: To help maintain a healthy aquarium, change filter cartridge every 3-4 weeks, or if water flow becomes obstructed. Remove filter cartridge when medicating water as carbon will absorb medications. Change out 10% of the waterweekly 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 before placing into filter
