Compared to traditional charcoal, our processed nutshell activated carbon has a superior adsorption and cleaning ability. It boasts a more developed pore structure, a more uniform pore distribution, and a longer lifespan. This translates to better and faster absorption of filth and sundries, offering clean and healthy water for your fish.

In contrast to crushed granule zeolite, our spherical zeolite is cleaner and more advanced. It can effectively adsorb ammonia, heavy metals, and other harmful components, helping to balance the pH value and achieve a stable water state. This improvement in water quality enhances the fertilization efficiency of aquatic plants, allowing them to grow faster and healthier.

Introducing the PF-S Filter Cartridges Refill for Top Fin Filter, a 16-pack of replacement aquarium filter cartridges compatible with Top Fin PF10 Power Filters. Each unit measures 5.5 * 3.1 inches (including the handle) or 5.1*3 inches without the handle, providing an ideal refill solution to keep your aquarium environment clean and healthy.

The filter is crafted with a dense dual-sided mesh, offering enhanced filtration capabilities. The use of Ultra-Activated carbon, instead of ordinary carbon, combined with processed zeolite, effectively filters and absorbs impurities in the water, ensuring a clean water source and a healthy growth environment for your fish.

The Nutshell Activated Carbon in our filter cartridges boasts a developed pore structure and uniform pore distribution, enabling it to adsorb dissolved pollutants from the water, improving water clarity and color, while also removing odors. Compared to other options, this provides a superior solution for maintaining a healthy aquatic environment for both fish and plants.

Complementing the Nutshell Activated Carbon, our filter cartridges also feature the Newest Filter Media – Processed Zeolite. Unlike crushed granule zeolite, our spherical zeolite is cleaner and more advanced, with the ability to adsorb ammonia, heavy metals, and other harmful components. This helps to balance the pH value and achieve a stable water state, ultimately improving the fertilization efficiency of aquatic plants and promoting their faster and healthier growth.

To ensure optimal performance, simply rinse the filter cartridges under clean, cool water to remove any surface dust. After rinsing, insert the cartridge into the flushing chamber, making sure it fits completely. For best results, replace the cartridges every 2 to 4 weeks, depending on the aquarium environment, to maintain a healthy water ecosystem.
