The Clear-Free Premium Under Gravel Filter by Penn-Plax is a remarkable addition to any aquarium enthusiast's toolkit. Designed to keep your fish tank water crystal clear, this air-driven filter utilizes an air pump to circulate water effectively while maintaining a pristine interior look. Unlike traditional filters with multiple moving parts, this filter offers a simplistic and user-friendly maintenance experience.

Featuring biological, chemical, and physical filtration, it ensures your aquatic environment remains healthy and vibrant. As air is pushed through the air stones and rises through the lift tubes, water is gently suctioned through the gravel bed, allowing beneficial anaerobic bacteria to flourish. This is crucial for breaking down harmful waste and promoting a balanced ecosystem.

One of the standout features of this filter is its ability to aerate your tank simultaneously, providing a dual function of filtration and aeration. This means not only is your water being filtered, but oxygen levels are also optimized for the wellbeing of your fish.

Included in the package are two filter plates, two adjustable lift tubes, and replaceable Filt-a-Carb activated carbon cartridges, allowing for a comprehensive filtration setup. The dimensions fit snugly in most 15 to 20-gallon aquariums, creating a seamless look under your gravel substrate.

With colors that may vary between blue or black for the filter plates, you can choose what best matches your aquarium setup. The installation process is straightforward and can be done in a clean dry tank, ensuring that adding gravel is mess-free. Embrace the simplicity and efficiency of the Clear-Free Premium Under Gravel Filter and give your aquatic life the clean environment it deserves!
