One downside is the noise level, which can be quite noticeable, especially in a home setting. Its considerable size and weight might also be cumbersome for some users, demanding significant space and effort to handle. Although it is built to last, any required maintenance due to its large size can be more challenging than smaller models. The filter comes with Bio-Floss Pads and a coarse Bio-Sponge, but users will need to purchase additional media for optimal performance. This filter is ideal for large tank owners who need powerful, customizable filtration and are willing to accommodate its size and noise levels.

The three large capacity media baskets enable customization of filtration, which is beneficial for maintaining optimal water conditions. The included filter media, such as the coarse bio-sponge and activated carbon, is effective at capturing debris and removing odors, enhancing water clarity.

There are some drawbacks to consider. While the noise level is generally low, it can still be somewhat noticeable in quiet environments. Maintenance is relatively easy, but the size of the unit might require more space than some users have available, especially in smaller setups.
