Tetra's Whisper EX is ready to go right out of the box. Simply adjust the in-take tube, place the filtration system on your aquarium and plug it in. The submerged motor begins filtering water immediately, no priming required - and operation is Whisper quiet.
Accurately determine when your carbon filter has expired with Tetra's Timestrip. Our patented technology allows you to see at a glance when it's time to replace your filter. The health of your fish depends on regular filter changes to remove toxins and other harmful impurities. Hang on back HOB power filter for easy installation.
Our newly re-designed filter carrier holds the filter – and the drips – so you don't have to. After discarding the old filter and inserting a new one, the carrier easily drops back into place within the filtration system. It's that simple!
Unlike other filters, the WhisperEX contains multiple layers of progressively denser floss to remove even the smallest particles from the water. The carbon inside eliminates odors, discoloration and, most importantly, harmful toxins. Finally, the BioScrubber® removes ammonia and nitrites that are deadly to your fish.
