Overview
The Fluval AquaClear 70 Power Filter delivers high-performance, customizable filtration for 40- to 70-gallon aquariums. Engineered with a unique multi-stage filtration system, it provides mechanical, chemical, and biological filtration to remove debris, odors, toxins, and discoloration—creating a clean, healthy environment for freshwater fish and plants. Featuring up to seven times more filtration volume than comparable hang-on-back filters, the AquaClear 70 maximizes water contact with its premium media: AquaClear Foam, Activated Carbon, and BioMax. This ensures superior debris removal, effective toxin adsorption, and long-lasting biological stability. The filter's energy-efficient, whisper-quiet pump keeps operating costs low, while its waterfall return gently breaks surface tension to improve oxygenation without disturbing fish. With a patented flow control feature, you can easily adjust water output to suit tank inhabitants, making it ideal for a wide variety of freshwater setups. A built-in media basket prevents bypass, ensuring water flows through every layer of filtration for maximum efficiency. Installation and maintenance are fast and simple, making the AquaClear 70 an excellent choice for aquarists seeking reliable, long-lasting filtration performance. (Packaging may vary.)
AquaClear gear is commonly used for freshwater planted tanks, nano aquascapes, and routine maintenance — always match capacity to your tank volume and livestock.
