The Aqueon QuietFlow LED Pro Aquarium Power Filter features a patented 5-stage advanced filtration system that includes mechanical, chemical, biological, wet/dry components and a filter pad. The LED cartridge change indicator is set off by rising water in your filter. Letting you know that your filter is clogged and it is time for a replacement. Great for use in both freshwater and saltwater aquariums, it is designed to ensure crystal clear water, increased oxygen levels, and healthier and more active fish.
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 2 - Chemical- Water is forced through the QuietFlow LED Pro's filter cartridge where the premium activated carbon effectively removes toxins, odors, and discoloration. Cartridges contain 25% more carbon than competing brands to help you maintain a flawless aquatic display.
Stage 3 - Biological- The QuietFlow LED Pro features a patented biological grid that provides a large surface area for the propagation of bacterial colonies. As water passes through the bio-holster, toxic ammonia and nitrates are actively removed by these beneficial bacteria.
Stage 4 - Wet/Dry- Water flows into the diffuser grid which removes additional toxins. It also increases dissolved oxygen levels, promoting increased fish activity and vitality.
Stage 5 - Filter Pad- The replaceable specialty filter pad adds extra filtration to water prior to returning it back in the aquarium.
