Rena Nexx foam filters are 30ppi foam filters that have the ideal thickness and pore size to trap small particles before they pass through the filter system. These filter pads can be used to replace the standard 4-sided API cartridges used in the Nexx filter. These filters will last for up to a year with just simple rinsing during maintenance. With these foams in place almost any filter material can be used in the filter canisters of the Nexx Filter so you can customize the filter in hundreds of configurations.?
Exclusively designed for each of the Fluval C Series Power Filters, the Fluval C2, C3, & C4 Foam Pads are highly porous, with a large surface area that mechanically filters large particles and debris from the aquarium, for a healthy and clean environment.
AquaClear Filter Insert Foam performs mechanical filtration by trapping particles and debris as they pass through the insert. This unique foam, designed for use with AquaClear Power Filters, features optimal pore size for efficient mechanical and biological filtration.
