To prefilter larger dirt particles, sera biofibres efficiently capture coarse debris. This helps shield the subsequent filter media from heavy pollution and enhances the biological performance of the filtration system. They are appropriate for filtering fresh water, saltwater, and pond water. Additionally, sera biofibres act as a fantastic spawning substrate and a safe haven for fry. Moreover, they are perfectly suited for transporting shrimp, as they offer a stable surface for the creatures in transport bags, minimizing stress during transit.

Maximize Biological Filtration Efficiency The original sera siporax Professional is designed for both freshwater and saltwater aquariums, as well as ponds. Regardless of the filter type (internal, external, or trickle), it optimizes the surface area necessary for biological filtration and provides an ideal substrate for the establishment of essential filter bacteria. The filtration and decomposition processes that occur at the bottom of natural bodies of water are crucial. Micro-organisms process organic waste, making it accessible as nutrients for aquatic plants, while effectively removing pollutants like ammonium, nitrite, and nitrate. In nature, minimal waste is generated per volume of water, allowing for sufficient micro-organism populations on the existing substrate. However, an aquarium is a compact ecosystem, making it essential to maximize the settling area to ensure complete and safe breakdown of organic residues. sera has achieved this with their innovative high-performance filter medium, sera siporax. Unlike other filter rings on the market, sera siporax is made from sintered glass. This unique material features a distinctive three-dimensional pore structure that significantly increases the surface area. Additionally, the fine pores create the perfect conditions for bacteria to thrive and decompose pollutants. Since it operates as an interconnected system, the bacteria are continuously flushed by water, enabling them to break down contaminants with optimal efficiency. Moreover, the exceptional pore configuration facilitates self-cleaning of the substrate, resulting in extended filter lifespan.

Bio Filtration Bioball 37mm EXCEPTIONAL FILTRATION! Each bio ball features spines that significantly enhance the surface area to nearly 2 square feet, allowing a substantial number of beneficial bacteria to thrive. These helpful bacteria work to decompose harmful organic waste. You will receive around 300 bio balls, each measuring 1-1/2 inches, conveniently packaged in a mesh bag. Simply rinse and they are ready for use. STURDY AND DISTINCTIVE! The spherical design and carefully arranged spines of our bio balls enable them to fit snugly into any filter shape or type without sacrificing surface area. Crafted from high-density plastic, these balls are lightweight yet durable enough to maintain their shape and will never degrade or wear out. Bio balls can be utilized loose or within the mesh bag featuring a plastic zipper. RELIABLE! Our bio balls are constructed from 100% polypropylene, making them a dependable choice for biological filtration in both fresh and saltwater environments. They are designed for use in koi ponds, water gardens, freshwater aquariums, saltwater tanks, aquaponics systems, fish hatcheries, and much more. SUPERIOR TO LAVA ROCK: Over time, porous lava rock can become blocked with debris, reducing its surface area and diminishing its capacity to support beneficial bacteria. In contrast, the uniquely arranged spines of our bio balls allow most debris to flow through easily. Lava rock features tiny pores that make cleaning a challenge, whereas bio balls typically do not require cleaning in most applications. Additionally, a bag of wet lava rock is significantly heavier than our bio balls. EASY TO CLEAN - When organic waste accumulates in the bio balls, they can be gently rinsed in dechlorinated water to eliminate debris and rejuvenate them. To prevent large particles from getting trapped in the bio balls, consider using our FilterFIrst dual-density bonded filter pad or a water polishing pad.
