Top-notch filter medium specifically designed for smaller aquariums sera siporax mini Professional has been specifically crafted for aquariums with a capacity of up to about 100 liters. It maximizes the surface area for beneficial bacteria while maintaining a compact design. This enables effective biological filtration even with smaller filter systems. As a result, water parameters are stabilized over time, and maintenance efforts are minimized. The processes of filtering and breaking down materials at the bottom of natural water bodies play a crucial role. Micro-organisms break down organic waste, making it a nutrient source for aquatic plants while removing harmful substances like ammonium, nitrite, and nitrate. In nature, minimal waste is produced relative to the water volume, so the existing bottom surface is adequate to support a healthy population of micro-organisms. However, an aquarium represents a small ecosystem within a confined space. Therefore, it is essential to maximize the surface area to ensure the thorough and safe breakdown of organic residues. sera has successfully achieved this with the innovative high-performance filter medium, sera siporax. In contrast to other filter rings on the market, sera siporax is made from sintered glass. This unique material features a distinctive three-dimensional pore structure, allowing for significant surface area enhancement. Additionally, the fine pores create ideal conditions for bacteria that decompose pollutants. Being part of an interconnected system, the bacteria are continuously washed by water, enabling them to break down pollutants with optimal efficiency. Moreover, the unique pore arrangement facilitates self-cleaning of the substrate, resulting in prolonged filter longevity.

sera siporax pond is an effective biological filter medium suitable for nearly all garden pond filtration systems With just 1 liter (1 US quart) of sera siporax pond, you can achieve the same settling area for beneficial bacteria as approximately 34 liters (9 US gal.) of traditional clay filter material. It's advisable to use sera biofibres coarse as a prefilter to keep larger particles from clogging the biofilter. sera siporax pond features an extensive network of open-pored tunnel structures, providing bacteria with an optimal supply of nutrients and minimal fresh water. The oxygen-poor environment within these tunnels encourages bacteria to break down nitrate to access sufficient oxygen. As a result, they consistently reduce nitrate levels, keeping your pond water clean and low in nitrate. One liter (one US quart) of sera siporax Professional boasts nearly the same biological filtration efficiency as 34 liters (9 US gal.) of clay filter media. Calculation formula for sera siporax pond: One liter (one US quart) of sera siporax pond can effectively purify 1,000 liters (264 US gal.) of pond water, accommodating 20 pond fish each measuring 10 cm (4 in.) or a similar biomass, which is approximately 1.5 kg (3.3 lb.) of fish consuming up to 40 g (1.4 oz.) of premium food daily, while effectively reducing organic pollutants over time.

Optimal Enhancement of Biological Filtration The original sera siporax Professional is designed for both freshwater and saltwater aquariums, as well as ponds. Regardless of the type of filter (internal, external, or trickle), it maximizes the surface area needed for biological purification and offers the ideal substrate for beneficial filter bacteria to thrive. The filtering and decomposition processes occurring at the bottom of natural water bodies play a crucial role. Organic waste is decomposed by microorganisms, making it available as nutrients for aquatic plants—effectively removing pollutants like ammonium, nitrite, and nitrate. In nature, the minimal waste generated per water volume means that the existing bottom surface is usually adequate to support a healthy population of microorganisms. However, an aquarium represents a compact biotope in limited space. Therefore, it is essential to maximize the settling area to ensure the thorough and safe breakdown of organic debris. sera has skillfully implemented this concept with the innovative high-performance filter medium, sera siporax. Unlike other filter media available 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. Simultaneously, the fine pores create optimal conditions for the bacteria that decompose pollutants. Because it forms an interconnected system, the bacteria are continuously flushed by water, allowing them to break down pollutants with maximum efficiency. Additionally, the unique pore arrangement enables self-cleaning of the substrate, resulting in extended filter longevity.

Optimal Enhancement of Biological Filtration The original sera siporax Professional is ideal for use in both freshwater and saltwater aquariums, as well as in ponds. Regardless of the filter type (internal/external/trickle filter), it optimizes the surface area needed for biological purification and provides the perfect substrate for the establishment of essential filter bacteria. The processes of filtering and breaking down materials in the substrate of natural waters play a crucial role. Organic waste is decomposed by microorganisms, making it available as nutrients for aquatic plants, while harmful substances like ammonium, nitrite, and nitrate are eliminated. In nature, minimal waste is produced per unit of water, so the existing substrate surface is adequate to support a healthy population of microorganisms. On the other hand, an aquarium represents a compact ecosystem in a limited space. Therefore, it's essential to maximize the available settling area to ensure the thorough and safe decomposition of organic remnants. sera has successfully achieved this with the innovative high-performance filter medium, sera siporax.

EHEIM phosphateoutA chemical phosphate remover that helps prevent algae growthEHEIM phosphateout is a unique iron-based compound designed for chemical filtration. This iron effectively captures phosphate, removing it from the water system and gradually lowering the phosphate levels in your aquarium. This process helps to curb algae proliferation within the tank.If you notice an increase in phosphate levels and consequently in algae growth, it's an indication that the filter medium is exhausted and needs to be replaced.EHEIM phosphateout is available for external filters in granulated form and for internal filters as a foam filter cartridge. It contains no harmful substances and is suitable for both freshwater and marine environments.Phosphate remover effectively prevents algae growthIron-based compound, free from harmful substancesCompatible with both freshwater and marine environmentsUse once (replace when phosphate levels begin to rise)Available in granulated form for external filters, and as a foam filter cartridge for internal filtersEHEIM phosphateout for internal filters aquaball and biopowerDepending on the type, chemical filter media can regulate the pH value and water hardness (such as peat) or lower phosphate levels and inhibit algae growth (like phosphateout).The pH level of tap water typically ranges from 7.3 to 7.8, making it slightly alkaline. However, many ornamental fish thrive in more acidic conditions, requiring a pH below 7.0. EHEIM TORFpellets can help lower pH levels and decrease water hardness.Phosphates primarily arise from organic waste in the aquarium water (such as fish remains and excrement) and contribute to algae blooms. EHEIM phosphateout binds these phosphates, effectively removing them from the water circulation.For the internal filters aquaball and biopower, there are specialized foam cartridges available instead of granules. These cartridges are infused with the iron compound that captures phosphates. If you observe an increase in phosphate levels, it's a sign that the cartridge has reached its limit and must be replaced.
