Stage 1 - Biological - The QuietFlow LED Pro's patented filter cartridge features dense floss that effectively traps dirt, debris, and particulates from your aquarium water.

Stage 5 - Filter Pad - The replaceable specialty filter pad adds extra filtration to water prior to returning it back in the aquarium.
