4 Customer Questions
Does this filter come already assembled and ready to insert in filter?
Answer by • Aug 01, 2019
These filters come unassembled.
What are the dimensions
Answer by • Apr 26, 2019
The small BIO-bag measures 3.8 inches long x 2.1 inches wide, the medium BIO-bag measures 5.2 inches long by 3 inches wide, and the large BIO-bag measures 6.4 inches long by 4.6 inches wide.
Can you use more than one in a 50 gal tank?
Answer by • Jun 30, 2022
More than one filter can be used in a 50 gallon tank. Tetra recommends using a filter system at each end of larger tanks. As long as the water does not backflow around the intake tube, the customer can also add a second bag or other media to the filter.
Does this come with the green plastic cartridge? We have the other style without the spot for the tablet, which cannot be used for this.
