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.

Fish Breeding Container The sera breeding container has a capacity of 2.5 liters (0.6 gal.), offering ample swimming area for fry, which is crucial for their swift and healthy development. Additionally, with a small amount of sera biofibres, it serves as an excellent spawning container.

This snail trap is perfect for those who prefer a chemical-free method of removal in a freshwater aquarium. The Sera Snail Collect effectively helps to manage an overpopulation of snails. By utilizing bait such as Sera O-Nip tablets, the snails are lured into the trap. The entrance is secured with sticks to prevent any fish from accidentally getting caught inside. Additionally, the Sera Snail Collect can also be employed to capture bristle worms in a marine aquarium. Instructions: Assemble the trap according to the provided images. Use Sera O-Nip as bait. Submerge the trap in the aquarium and ensure it is weighed down.

Robust pond filter designed for ponds of up to 40,000 liters (10,568 US gal.) or Koi ponds with a maximum capacity of 24,000 liters (6,340 US gal.). The sera Koi Professional 24000 Pond Filter combines contemporary functionality with elegant design: it is compact yet highly efficient, catering to ponds of 40,000 liters (10,568 US gal.) and Koi ponds of 24,000 liters (6,340 US gal.). This filter is engineered based on the latest advancements in flow technology, while also boasting a visually appealing exterior. The water undergoes a four-step purification process: initially, it is treated with UV-C radiation that reduces both pathogens and algae in the physical stage. Next, it passes through a detention chamber into the mechanical purification stage, which features a curved stainless steel split sieve with a mesh size of 200 µm. This mechanism captures not only larger particles but also the algae cells that have been treated and clogged by the UV-C radiation. When an algae bloom is imminent (“green water”), two fine mesh filter sponges can be effortlessly integrated beneath the split sieve to eliminate even single-celled algae from the pond water. If the sponges are not cleaned promptly, the water will flow directly into the biological stage via a safety overflow. Here, the water is initially distributed using a Matala mat, enriched with oxygen, and trickles over the high-performance filter medium, sera siporax pond, that is populated by filter bacteria. The cleansed water is then returned to the pond through a detention step. Equipment: Basic version (item no. 08651)1 pc. filter body30 l/3 x 2 kg (3 x 4.4 lb.) sera siporax pond1 pc.

For easy monitoring of marine water density, you can determine the salinity (salt content) from the measured density. It's essential to maintain a consistent salinity level in your aquarium, so it's important to check the water regularly. To perform the test, fill a tall glass with the water you want to assess, then read the scale of the submerged hydrometer based on how deep it is immersed.

Pond pumps for pond filters, brooks, and fountains The sera pond pumps PP integrate essential features for contemporary pond enthusiasts: these pumps are conveniently housed within an elegantly designed basket with a handle, ensuring a stable position in the pond while safeguarding against larger debris. Each pump is fitted with an optimized impeller that significantly reduces the likelihood of clogging, thus extending maintenance intervals. The energy-efficient asynchronous motor is robust yet economical, offering increased pressure along with larger flow rates while consuming less energy. These pumps are primarily intended for submersion in the pond, but they can also be utilized in a dry installation without the basket.
