Our Premium TRUE dual density filter pads are the professions choice, constructed of durable polyester fibers bonded by our special resin to give it exceptional strength. The top layer's open fiber construction traps larger particles while the bottom layer's dense fiber network traps fine particles - working together to produce crystal clear water in your fish tank.
The lower section of our pads is made by taking layers of resilient fibers through a process called needling to tighten and entangle the fibers into a dense network producing a thin firm layer, perfect for removing fine debris.
The fibers in our dual density filter pads effectively trap uneaten foods, waste excreted by livestock, decaying plants, detritus, dust, and other floating particulates from aquarium water. Changing this filter pad often will increase water quality by removing collected solids BEFORE they continue to break down and add additional unwanted algae feeding nutrients to your aquarium water.
The Premium filter pads are typically used as a pre-filter for wet/dry filters, sumps, and canister filters to clean water in freshwater, saltwater, reef aquariums and other types of fish tanks. They also provide mechanical filtration in aquaponics systems, turtle tanks, terrariums, and much more.
