Filter-Max III Pre-Filter
The Filter-Max Pre-Filter filters the water before it reaches the main filter. It provides both mechanical and biological filtration. Aerobic bacteria colonize the sponge, providing a bacterial substrate to facilitate the nitrogen cycle.
Advantages: Maintains the biological filtration when the main filter is cleaned, or changed. Prevents debris from clogging the intake, by distributing the suction evenly down the length of the sponge. prevents small fish, or babies from being suctioned into the main filter. Can be used with most power filters, canister filters, and power heads. Includes three adapters for use with various main filter intake tubes. Can be used in the vertical or horizontal position. Easy to clean, just rinse and squeeze!
