Frequently Asked Questions about Aquarium & Fish Tank Filter Cartridges

What are the components of an aquarium filter?

Common components of an aquarium filter include a filter media, circulating pump, and the filter housing. The filter media can range in material from sponge to mesh to floss to bio-balls.

How often do you replace the cartridge of a fish tank filter?

Generally speaking, you should replace a fish tank filter about once a month or every 6 weeks. However, this can vary from filter to filter. Usually, when you start to notice decreased water flow, you know it's either time to clean or replace your fish tank filter cartridge.

Do I need a specific cartridge for my aquarium filter?

Yes, every aquarium filter has its own filtration needs, so specific aquarium cartridges are needed. Some cartridges are designed to remove specific elements like chlorine and sediment. Additionally, some fish tank filter cartridges are only compatible with certain filter models. Before replacing fish tank filter cartridges, check the aquarium's filter model to ensure compatibility.
