The WhisperEX Filter easily hangs on the back of your tank. The Bio-Scrubber helps ensure crystal clear water. THE ESSENCE OF EASE It is ready to go right out of the box, you only have to adjust the intake tube to the proper depth and plug it in. No priming of the filter is necessary. There is an easy access door located on top of the filter that stays in place while changing out the filter cartridges and the Filter Cartridge Carrier helps keep your hands away from used cartridges, helping eliminate any unwanted drips. The Whisper EX Filters also have a submerged motor requiring less maintenance than other external models while creating one of the most silent filters on the market. THE CONTOUR OF CLEAN Whisper EX Filtration Systems have scientifically engineered water flow. The rounded shape creates a circular water flow that prevents sediment from forming in the bottom of the system chamber. Water is forced through multi-density carbon filters that suspend the carbon for greater contact and improved filtration. The filters are designed with a multi-density floss structure that captures a range of unwanted particles. The Activated Carbon in the Filter Cartridges allow for the elimination of odors, water discolorations, and detrimental toxins. Whisper EX models also have Tetra's patented Bio-Scrubber technology. The bristles of the Bio- Scrubber provide more surface area for biological conversion of toxic ammonia and nitrites to harmless compounds and the design of the Bio-Scrubber Cartridge allows for it to be virtually clog-free. The Whisper EX Filtration Systems have the innovative technology that gives the most water contact-to-filter ratio. This will give you the ultimate in water quality, and fish and plant health.
