This test allows for easy and accurate monitoring of calcium levels in increments of 20 mg/l (ppm) for approximately 7,500 mg (ppm) of calcium. If calcium levels are found to be too low, add sera marin COMPONENT 1 Ca. For levels that are too high, performing a partial water change will be beneficial.

Quick and Easy Monitoring Routine Monitoring or Safety Check: The sera Quick Test offers a convenient way to assess the essential water parameters (pH level, carbonate hardness, total hardness, nitrate, nitrite, and chlorine) in your aquarium using just one test strip. Simply dip a test strip into your tank for a second, wait for 1 minute, and then match the color intensity to the chart provided on the packaging. This straightforward method is perfect for beginners aiming to achieve the best water quality in their aquariums. If the results indicate any discrepancies from the ideal levels, the sera liquid tests can help you accurately identify the differences.

Marine salt for R/O and tap water Thanks to its exceptional consistency and uniform grain size, sera marin salt dissolves swiftly and leaves no residues, resulting in crystal clear marine water. It helps to establish natural GH and KH levels, while being rich in calcium and magnesium in biologically suitable proportions. The pH value is kept stable and accurate, thanks to the natural buffering system found in sera marin salt. Through a unique process, sera marin salt retains trace elements in a manner that keeps them consistently dissolved and available for extended periods. This salt does not include any substances that could artificially boost protein skimmer performance. Moreover, it is free from nitrates, silicates, and phosphates. Sera (sea salt without nitrates, phosphates, and silicates) is rich in calcium and all essential trace elements required for successfully cultivating ornamental algae and lower resins in seawater. It contains a blend of special substances that aid in the removal of harmful elements such as heavy metals and copper. The salt dissolves rapidly and without leaving deposits. With its natural buffering capability, it ensures an optimal and stable pH level. Instructions for use: Dissolve Sera marin salt (approximately 33 g per liter of water) to achieve a water density of 1.022 to 1.024 g/ml in a container using treated water (osmosis) or chlorine-free tap water. Aerate for 24 hours or thoroughly mix with a submersible pump to introduce oxygen and carbon dioxide. Warning: Avoid dissolving sea salt directly in an active aquarium! We suggest replacing 5-10% of the aquarium water monthly and treating it with sera aquatan and sera bio reef clear to enhance water quality. When setting up a new aquarium, treat the water with Sera aquatan and Sera bio reef clear, and allow the aquarium, along with the connected equipment (pumps, heaters, filter...), to run for at least 14 days to ensure biological stabilization before adding any fish.

Top-notch premium marine salt, nature-inspired The latest sera marin reef salt is a top-quality premium marine salt that mimics natural conditions, perfect for thriving reefs. It is formulated from individual components, ensuring that pollutants are effectively eliminated. This consistently high quality minimizes stress during water changes. Even the needs of the most discerning invertebrates, including stony corals, are met with ease. Deficiencies are successfully prevented. Sera marin reef salt includes all essential macro and trace elements, which play crucial roles in the skeletal development of invertebrates as well as the production of enzymes and color pigments. Its fine grain size allows for quick and easy solubility, thanks to the use of pure single components.

Sera Plant Color T8 Fluorescent Aquarium Lamp 30 Watt This red-blue light is designed to promote optimal plant growth in both aquariums and terrariums, with a temperature of 4900 Kelvin. It not only intensifies the natural hues of your fish and plants but also enhances the exotic atmosphere of your aquarium. Additionally, it boosts photosynthesis, leading to robust plant development. Length: 90 cm

12,000 Kelvin - A vibrant and intense blue light - Mimics the illumination found in tropical rivers and lakes. Thanks to its well-balanced spectrum, sera Blue sky can be utilized on its own or paired with sera Deep sea as a lighting solution for marine aquariums. When combined with SERA Tropic Sun, it creates the ideal lighting for freshwater aquariums. Effective aquarium lighting is essential not only for fish but also for any live plants thriving in your aquarium. Plants require light for photosynthesis, which allows them to create food from carbon dioxide and water. For instance, tropical plants necessitate 12 hours of light each day, while plants from cooler waters need lighting that changes with the seasons. IMPORTANT: The lifespan of aquarium lamps is 12 months. The lamp's spectrum gradually shifts, and after this period, it will no longer serve effectively as an aquarium light for its intended purpose. To achieve optimal results, it is recommended to replace aquarium lights every 12 months. In essence, watts indicate the energy consumption of a light, lumens measure its brightness, and Kelvins define the color of the light.

Full spectrum warm sunlight designed specifically for freshwater aquariums. This spectrum closely mimics tropical daylight, enhancing natural colors. Sera Tropic Sun Royal delivers optimal lighting, providing a sunny, warm daylight effect in tropical aquariums that mirror rainforests. This lamp features a broad spectrum that ensures accurate color reproduction. With a color temperature of 4700K, it captures the soft glow of tropical morning sunlight. The color rendering index, according to German standards (DIN), is lA (the highest rating), reflecting natural sunlight at 92%. The emission of ultraviolet rays is minimized to just 2%, focusing on UV A and UV B wavelengths necessary for terrariums that emulate swamps and tropical rainforests, where inhabitants such as spiders, scorpions, and insects require low UV intensity. The smooth poisonous frog relies on this level of ultraviolet light to avoid vitamin deficiency issues. Additionally, many terrarium animals depend on UV A and UV B light to synthesize vitamin D in their skin. For these reasons, Sera Tropic Sun Royal also serves as an excellent light source for bird cages. Please be aware: the lifespan of aquarium lamps is 12 months. The spectrum of the lamp gradually shifts, and after this time, it can no longer effectively serve its purpose as an aquarium lamp. For optimal performance, it is recommended to replace aquarium lamps every 12 months. Length: 90 cm.

Specialized nutrition designed for vibrant colors and healthy growth, these floating granules feature a unique ring and core structure enriched with high levels of pigment-dense spirulina and astaxanthin-rich Haematococcus algae. This formulation ensures remarkable color intensity and clear definition within color zones, preventing any yellowing of white patterns while delivering a lustrous sheen and an optimal amino acid balance for superior growth. Proper nutrition is essential for highlighting the stunning colors of Koi. The significant inclusion of spirulina microalgae in this feed promotes color saturation and enhancement, alongside clear demarcation of color zones. White areas remain bright without an unsightly yellow tint. Spirulina boasts over 50% protein content, providing all essential amino acids along with numerous unsaturated fatty acids. Furthermore, the algae are rich in various vitamins and minerals. Astaxanthin, in particular, enhances coloration, especially in red regions. This pigment, akin to vitamins, bolsters the immune system, acts as an antioxidant, and supports reproductive health. Only the natural, highly bioavailable form of astaxanthin is utilized in sera feed, with Haematococcus algae being the primary source (60.5 mg of astaxanthin per kg of feed). Additionally, ingredients such as krill and spirulina contribute to the supply of astaxanthin and other vital pigments. Koi Professional Color is composed of two essential parts: a feeding ring and a feeding core. This innovative design is achieved through a specialized co-extrusion manufacturing process that allows for the combination of differently processed components. The ring is made from high-quality natural ingredients, including spirulina and Haematococcus, ensuring both outstanding colors and adequate nutrition. The core includes essential vitamins, minerals, and trace elements to promote healthy growth and a robust immune system.
