Biological filter media designed for phosphate elimination Sera siporax algovec Professional serves as a biological filter medium that effectively eliminates phosphate through the action of beneficial bacteria. An excess of phosphate can promote unwanted algae growth. The bacteria utilize nutrients in a stable and enduring form, beginning their activity shortly after they come into contact with water. They reproduce and remain functional for an extended period. The carrier material of sera siporax enhances bacterial performance by providing optimal conditions for settlement, thanks to its nature-inspired surface structure. Using sera siporax algovec Professional as a preventive measure will help to avoid phosphate accumulation.

Emergency Care for Aquariums Quickly eliminates harmful ammonia and nitrite Neutralizes heavy metals including lead and copper Effective in removing chlorine and chloramines Reduces nitrate levels, consequently decreasing algae growth Due to various destabilizing factors such as overfeeding, high fish populations, new aquarium setups, extensive maintenance efforts, or the use of treatments, spikes in harmful pollutants like ammonia and nitrite can unexpectedly arise in aquarium water. In these urgent scenarios, sera toxivec promptly eradicates these toxic elements along with other hazardous substances like chlorine and heavy metals. The natural balance swiftly restores itself after the pollutants are eliminated, eliminating the need for frequent, stressful water changes.

Natural Tropical Black Water Maintains a slightly acidic pH level over an extended period Gently lowers water hardness Provides a steady release of humic and fulvic acids Natural chelation helps to bind harmful heavy metals Offers protection against mold and pathogens affecting roe Supports the protective layer of skin mucus Naturally inhibits algae growth with a light filter The subtle amber hue promotes stress reduction Black water creates a species-friendly environment for tropical aquariums The natural habitat for fish like discus, angelfish, or neons is typically defined by very soft, slightly acidic, and often dark water. These tropical black water conditions can be easily and sustainably achieved using sera super peat. This functional granulate, derived from natural black peat and placed in the filter, effectively lowers KH over time and stabilizes the pH in the slightly acidic range. Moreover, it continuously releases beneficial humic and fulvic acids.

Gentle water - but with safety in mind Reduces pH and KH Modifies carbonate hardness Controls the pH level Creates suitable soft and mildly acidic water Certain fish species, such as discus and angelfish, thrive in very soft water and specifically need these conditions for successful breeding. However, the water might have excessively high carbonate hardness (KH), or the pH could have increased significantly due to natural metabolic activities, even when keeping other types of fish. In such situations, sera pH/KH-minus offers dependable and swift assistance. It instantly and accurately lowers and regulates both the pH and KH levels. This establishes optimal keeping conditions that greatly enhance the health and well-being of your fish. Tip: Set the KH to 4°dKH using sera pH/KH-minus and then add sera super peat in the filter to consistently maintain tropical softwater conditions.

Sera Plant Color T8 Fluorescent Aquarium Lamp 30 Watt This red-blue light is designed to promote the best growth of plants in both aquariums and terrariums. 4900 Kelvin Amplifies the vibrant colors of your fish and plants Brings an exotic ambiance to your aquarium Boosts photosynthesis for robust plant development 90 cm

Safe Soft Water Solutions The pH and KH will decrease Modifies the carbonate hardness Controls the pH level Creates ideal soft and slightly acidic water for aquatic species Certain fish species, such as discus and angelfish, thrive in very soft water and require these conditions particularly during breeding. Additionally, when breeding other fish varieties, the water may exhibit high carbonate hardness (KH) or the pH level might elevate excessively due to natural metabolic processes. In such situations, sera pH/KH-minus provides a reliable and swift solution. The pH level and KH decrease instantly and are effectively controlled. This establishes the right environment for breeding, enhancing the vitality and overall health of the fish. Tip: Adjust the KH to 4°dkH using sera pH/KH-minus, and then add sera super peat to the filter to sustain the ideal tropical soft water conditions over an extended period.  

An excellent foundation for thriving plant growth sera floredepot is designed to be placed beneath the substrate (sand, gravel) when establishing your aquarium.

Emergency Care for Aquariums Quickly eliminates harmful ammonia and nitrite Neutralizes heavy metals like lead and copper Eradicates chlorine and chloramines Reduces nitrate levels and, in turn, minimizes algae proliferation Factors such as overfeeding, high fish populations, new aquarium setups, increased maintenance demands, or the application of treatments can lead to sudden spikes in harmful pollutants like ammonia and nitrite in your aquarium water. In these urgent situations, sera toxivec swiftly eliminates these toxic elements along with other hazardous substances such as chlorine and heavy metals. The natural balance of your aquarium is quickly restored after the pollutants are removed, eliminating the need for stressful, frequent water changes.

Stability and Assurance It establishes a buffer and maintains the pH level It helps combat biogenic scaling Creates optimal conditions for specific species (e.g. African Cichlids) Carbonate hardness (KH) is among the less critical factors of aquarium water quality. The majority of fish in freshwater aquariums prefer somewhat harder water. Furthermore, KH serves as a buffer that shields against harmful pH fluctuations (including sudden increases in acidity). For all community aquariums, it's essential to maintain a minimum KH of 6°dkH (even higher for particular species like African Cichlids). This helps ensure the health of the fish and keeps the aquarium water stable and manageable. Sera KH/pH-plus effectively raises KH to the desired level over the long term. The pH will gradually increase and, most importantly, remain securely stabilized.

Enjoy clear breathing with our purifying solution Provides emergency assistance during sudden oxygen shortages Helps reduce stress through enhanced oxygen levels Simple and safe to use Aids in the decomposition of sludge The respiration of aquarium residents, along with various natural decomposition processes, continuously utilizes oxygen. Certain situations may lead to sudden shortages. This can occur due to elevated water temperatures, significant organic contamination, and oxygen-depleting treatment for illnesses. Even minor oxygen shortages can induce stress, while severe deficiencies can result in fish fatalities. With sera O2 plus, which is easily sprinkled into the water, you can instantly enrich the oxygen levels, thereby enhancing the habitat for all aquatic life. Moreover, optimal oxygen levels accelerate decomposition processes, keeping your aquarium clear and free from unpleasant odors.

An excellent foundation for thriving plant care sera floredepot is positioned beneath the primary substrate (sand, gravel) when establishing your aquarium. This carefully formulated mix of sand, peat, vital nutrients, and trace elements promotes rapid plant growth. Additionally, plants receive essential nutrients during their initial growth phase (4 - 6 weeks). The unique composition of the substrate encourages the development of robust roots.
