Tetra Whisper Filter - IQ 20

The latest Whisper IQ20 filter offers premium technology for aquarium cleaniness, health, and maximum quiet. A flow control switch adjusts the IQ20 down to as low as 10GPH to not disturb the surface for fish like bettas, as well as to keep the water disturbance to a minimum while feeding or trying to keep your room quiet. A separate motor and upgraded impeller system is designed to keep the moving parts away and further eliminate noise. Forget about annoying priming - the IQ10's motor system sits right in the water for plug and play readiness. Each Whisper IQ Filter also includes a Bio-Grid system for supporting optimal beneficial bacteria growth to support biological filtration. Other features include a telescoping intake tube to adjust to the depth of your tank, as well as a SmartSpill water agitator on the outflow to add oxygen and break up the flow for a quieter drop-off. Just add a Stay Clean Bio-Bag and you're ready to roll. Includes everything you'll need to get started, including 1 Large-size Stay Clean Bio-Bag. 130 gph Max Flow and good for aquariums up to 20 Gallons.

For best results, it's recommended to change your Whisper Stay Clean Cartridge monthly.
