Internal and external filters for the aquarium: which one is better to choose

When choosing between external and internal aquarium filters, there are several important factors to consider. UAportal has conducted a thorough comparison of filters.

Size

For large aquariums, an external filter may be more suitable due to the higher flow rate and larger water volume. Conversely, for smaller tanks, an internal filter may be more compact and easier to install due to its compact size.

Maintenance and cleaning

External filters are usually easier to maintain because they can be accessed from outside the aquarium, which reduces interference with the aquarium environment. Internal filters, while simpler in design, may require more frequent cleaning as they accumulate debris more quickly.

Noise

Internal filters are known for their quiet operation because they are submerged in the water, muffling the sound. On the other hand, external aqua filters can be noisier due to their location outside the aquarium.

Filtration capacity

External filters often provide better cleaning efficiency due to multiple compartments for different filter media, which ensures superior water quality. Internal systems, while usually sufficient for smaller aquariums, can provide the same level of filtration.

Cost

External filters tend to be more expensive initially, but they provide greater long-term cost-effectiveness due to their higher performance and lower maintenance needs. Internal filters are initially more affordable but may require higher ongoing costs due to possible frequent replacement.
