Advice of Use:
To help maintain a healthy aquarium, change the filter cartridge every 3 – 4 weeks. Remove the cartridge when medicating the water as carbon will absorb medications. Change out 10%of the water weekly or 25% monthly. Use a water conditioner every time you add fresh tap water to aquarium water. Never use soap, detergents or cleaning agents while cleaning aquarium or equipment as they can harm your fish.
Directions for Use:
1. Rinse the filter cartridge under cool tap water to remove dust.
2. Insert the cartridge, opening side up, into the frame (included with the Top Fin Multi-Stage Internal Filter).
