Advice for 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 your aquarium. Be sure your bucket is only used for aquarium water. Never use soap, detergents or cleaning agents while cleaning the aquarium or equipment as they can harm your fish.
