Conclusion

Aquarium filter systems are designed to remove unwanted materials from the water in your aquarium. There are a variety of different types of filters available on the market, but the most common type of filter used in saltwater aquariums is the canister filter.

Canister filters are designed to remove a variety of different types of materials from the water, including dissolved organic compounds, ammonia, nitrites, nitrates, and phosphate.

Canister filters are typically placed underneath the aquarium, and they use a series of pumps and tubes to draw water from the aquarium and send it through the filter media. The filter media is typically made of a variety of different materials, including activated carbon, zeolite, and biomedia.

The different types of filter media are designed to remove different types of materials from the water.

Activated carbon is typically used to remove dissolved organic compounds, ammonia, and nitrites from the water. Zeolite is typically used to remove nitrates from the water. Biomedia is typically used to remove phosphate from the water.
