Using these Fluval filter media bags is a breeze. First, grab a bag and fill it with enough filter media. You can find many types of filter media at your local pet store. After filling, use the enclosed fastener to close the bag tightly. Then, pick the compartment in your Fluval canister filter system where you want to place the bag. That's it, you're ready to use your filter! As for maintenance, check the bags regularly. If they look dirty or clogged, you can gently rinse them under lukewarm water. Don't use any harsh chemicals as they might damage the bags. Replace the bags when they start to show signs of wear and tear, usually after a few months of use depending on how often you use your filter.
