KoiPro Bacteria House 24 pieces – filter mediumKoiPro Bacteria House is a highly porous ceramic filter medium for koi ponds, trickle filters and Bakki Shower. The 24 filter elements provide ample surface area for beneficial filter bacteria to colonise and help maintain stable water quality.KoiPro Bacteria House filter medium is a highly porous, ceramic filter material for koi ponds and garden ponds. The fine pore structure provides a large surface area for beneficial filter bacteria to colonise, which play an important role in breaking down pollutants such as ammonium/ammonia and nitrite. As a result, the filter medium supports stable biological filtration performance in the pond. Bacteria House has a water absorption rate of 80 %. Thanks to the microscopically small pores, bacteria can colonise the material quickly and break down organic pollutants in the pond water. At the same time, the porous structure also acts mechanically, as coarser organic debris is retained and can be further broken down during the filtration process. The filter medium is particularly well suited to Bakki Shower / trickle filters, but can also be used in other pond filters. One pack contains 24 ceramic filter elements, each approximately 38 × 38 mm thick and 160 mm long.Your benefits at a glanceHighly porous ceramic filter mediumSuitable for koi ponds and garden pondsSupports biological filtrationLarge surface area for beneficial filter bacteriaHelps break down ammonium/ammonia and nitriteWater absorption rate of approx. 80 %Can also be used as a mechanical filter mediumSuitable for Bakki Shower and trickle filtersAlso suitable for other pond filtersPromotes stable water qualityDoes not become clogged quickly, unlike conventional mediaContents: 24 piecesDimensions per element: approx. 38 × 38 × 160 mmInstructions for useBefore first use, briefly rinse the filter medium with pond water or clear water to remove any loose debris. Then place the Bacteria House elements in the filter so that they are well flushed or sprayed by the water. They are particularly effective when used in trickle filters or Bakki Shower systems, as there is plenty of oxygen available for the filter bacteria there.Zoo Roco TipBiological filter media work best when they are well supplied with oxygen and the pond filter is running continuously. After initial installation, the medium takes some time for sufficient filter bacteria to colonise it. During this running-in phase, water parameters should be checked regularly.

JBL CRISTALPROFI SYMECPAD Filter fleece for crystal clear water The JBL CRISTALPROFI SYMECPAD is the ideal filter fleece for the JBL CristalProfi filter and ensures crystal-clear water in your freshwater and saltwater aquarium. With its practical application, it replaces filter sponges in the filter baskets and ensures particularly fine mechanical filtration. It is the perfect solution for reliably removing even the smallest dirt particles from the water and optimizing the water quality. Product features: Easy to use: The JBL CRISTALPROFI SYMECPAD can be easily inserted into the filter baskets of the JBL CristalProfi filter, where it replaces filter sponges. It ensures effective fine filtration and thus contributes to a clear and healthy water environment. Suitable for fresh and salt water: Whether freshwater or saltwater aquarium, the SYMECPAD is ideally suited for both types of aquarium and guarantees thorough mechanical cleaning of the water. High filtration performance: The filter fleece removes even the finest dirt particles from the water and ensures a visually clear water surface. It therefore improves visibility and contributes to a better quality of life for your aquarium inhabitants. One-off cleaning: The SYMECPAD can be washed out once if it is very dirty. However, it should be completely replaced after the first cleaning, as the fine structure of the fleece does not allow multiple cleaning cycles. Durable and efficient: Compared to filter sponges, filter ceramics or sintered glass material, the SYMECPAD is specially designed for finer filtration and enables the targeted removal of dirt particles that other filter materials may not be able to remove. Zoo Roco tips for use: Use the JBL CRISTALPROFI SYMECPAD as a fine filter material in your JBL CristalProfi filter to effectively remove even the smallest dirt particles. If the fleece is heavily soiled, you can wash it out once, but be sure to replace it after cleaning as it cannot be washed several times. To ensure constant filtration performance, we recommend replacing the filter fleece regularly and not using it for too long.

Sera Siporax - the power pack for your aquarium filter achieves the best water quality through biological filtration suitable for freshwater and saltwater aquariums Sera siporax was developed on the basis of an aquatic biological study. The pore structure of the nitrifying (nitrite-degrading) layers at the bottom of the water was reproduced with great technological effort. The result: thanks to the special manufacturing process, each individual roll of Sera siporax offers around 1 m2 "rolled up" surface area that can be colonised by bacteria. Compared to other ceramic filter media, this is precisely the advantage of Sera siporax. It is not just the nominal surface area that characterises an excellent filter material, but only the surface area of the pore structure, which is large enough for bacteria to colonise. A small - but significant - difference. Furthermore, there is always an optimum flow rate inside Sera siporax. The special, three-dimensionally cross-linked pore structure leads to this effect. In this way, the colonised bacteria are always supplied with sufficient oxygen and are not flushed from the filter medium due to excessively fast flow. The colonisation conditions for the cleaning bacteria, as provided by Sera siporax, are the essential basis for a stable and particularly active bio-film that ensures reliable pollutant degradation. sera siporax is the optimal high-performance bio filter material for all internal and external filters and offers an effective colonisation area of 270 m2 per litre of sera siporax.
